What is a Nitrogen Generator and Why Should You Buy One?

For many businesses, nitrogen gas is deeply integrated into the workday. Industries ranging from food processing to mining use this resource regularly, and the supply of it is essential to the core of operations. Unfortunately, traditional nitrogen gas acquisition requires the rental, delivery, installation, and removal of high-pressure cylinders. Canisters are inefficient, causing a lapse in production if delivery is late or supply is low. This process is not only more expensive than it needs to be, but it also creates more opportunities for workplace injuries.

Nitrogen generators, on the other hand, offer a better option. If your company is a regular user of nitrogen gas, consider installing your own nitrogen generator to enjoy the extensive benefits they provide.

What is a Nitrogen Generator?

Before exploring the many advantages of on-site nitrogen generation, it’s imperative to know what a nitrogen generator is and how it works. These machines perform processes called Pressure Swing Adsorption (PSA) and Membrane Technology, which extract nitrogen from the air and compress it.

Nitrogen generators offer a continuous flow of pure nitrogen right to your production floor and eliminate any need to wait for canister deliveries or remain at the mercy of supplier prices. While the resource provided is essentially the same, the generator produces the nitrogen rather than having it transported in cylinders.

Uses of a Nitrogen Generator

There are many applications for nitrogen gas across a variety of industries. Any industry that currently uses nitrogen canister, cylinder, dewar, or liquid deliveries can benefit from an in-house nitrogen generation system. Depending on what line of business you’re in, a nitrogen gas generator can work seamlessly into your manufacturing process in different ways.

One of the most common industries for nitrogen gas is food and beverage production. Nitrogen helps to preserve food inside its packaging and extend its shelf life. This is doubly important for bulk food products that might be stored for longer periods, as well as foods that don’t include preservatives in their ingredient lists.

The wine industry also benefits from nitrogen, as it helps keep the wine from going bad. In a non-consumable sense, nitrogen also extends the shelf life of things like paint and household solvents and prevents moisture and condensation in electronic part production. Additionally, nitrogen plays an integral role in quality assurance and consistency. On-site generators allow you to perform all of these tasks and more without a third-party supplier.

Why Make the Switch?

While disrupting and changing your current process can seem daunting, owning a nitrogen generator has numerous benefits that far outweigh any reservations you may have. The advantages of a nitrogen generator are widespread and touch on nearly every aspect of your business.

nitrogen-applications

Below are the primary benefits of switching to an in-house nitrogen generator:

1. Improved Safety

Replacing and transporting nitrogen cylinders presents a safety hazard to your team. Nitrogen generators stabilize the gas, so you don’t have to worry about explosions or injuries. In fact, they’re so safe that they can be installed right on the floor of your production room where they’re needed most. There is no risk to your employees’ wellbeing.

2. Unparalleled Reliability

Unlike canisters, cylinders, dewars, and liquid methods, nitrogen generators produce an infinite supply of gas, so you never have to worry about pausing production to wait for a delivery. While local nitrogen deliveries can run out or run late, a generator system keeps up with your demand and works on your schedule.

3. Fewer Wasted Resources

Approximately 10 to 20 percent of a canister’s, cylinder’s, dewar’s or liquid method’s nitrogen gas is left unused. This can lead to higher costs and waste production levels. Generators do not have this issue, so you can rest assured that all of your reserves are being used efficiently.

4. Increased Savings

While canisters, cylinders, dewars, and liquid methods come with expensive rental and delivery fees and restrictive contracts, generators require very little beyond their initial cost. In fact, most companies see a return on investment in under two years.

After the initial investment is recouped, generators cost about one-tenth of the price of canisters, cylinders, dewars, and liquid methods per year. That’s a 90 percent difference in operating costs, which creates a significant surplus for most companies.

5. Customization Options

Canister, cylinders, dewars, and liquid methods are one-size-fits-all, but generators can be tailored to meet your exact requirements. This means that your machine will work at maximum efficiency, producing the precise amount of gas you need to maintain operations.

Bottom Line

Nitrogen generators can revolutionize your company’s production process, lowering your utility costs and improving your efficiency. Without dealing with the hassles of nitrogen cylinder delivery, you can grow your business to new heights.

Ultrasonic Pretreatment in Anaerobic Digestion of Sewage Sludge

Anaerobic digestion process comprises of four major steps – hydrolysis, acidogenesis, acetogenesis and methanogenesis. The biological hydrolysis is the rate limiting step and pretreatment of sludge by chemical, mechanical or thermal disintegration can improve the anaerobic digestion process. Ultrasonic disintegration is a method for breakup of microbial cells to extract intracellular material.

Ultrasound activated sludge disintegration could positively affect anaerobic digestion of sewage sludge. Due to sludge disintegration, organic compounds are transferred from the sludge solids into the aqueous phase resulting in an enhanced biodegradability. Therefore disintegration of sewage sludge is a promising method to enhance anaerobic digestion rates and lead to reduce the volume of sludge digesters.

The addition of disintegrated surplus activated sludge and/or foam to the process of sludge anaerobic digestion can lead to markedly better effects of sludge handling at wastewater treatment plants. In the case of disintegrated activated sludge and/or foam addition to the process of anaerobic digestion it is possible to achieve an even twice a higher production of biogas. Here are few examples:

STP Bad Bramstedt, Germany (4.49 MGD)

  • First fundamental study on pilot scale by Technical University of Hamburg-Harburg, 3 years, 1997 – 1999
  • reduction in digestion time from 20 to 4 days without losses in degradation efficiency
  • increase in biogas production by a factor of 4
  • reduction of digested sludge mass of 25%

STP Ahrensburg, Germany (2.64 MGD)

  • Preliminary test on pilot-scale by Technical University of Hamburg-Harburg, 6 months, 1999
  • increase in VS destruction of 20%
  • increase in biogas production of 20%

STP Bamberg, Germany (12.15 MGD)

  • Preliminary full-scale test, 4 months, 2002 2) Full-scale installation since June 2004
  • increase in VS destruction of 30%
  • increase in biogas production of 30%
  • avoided the construction of a new anaerobic digester

STP Freising, Germany (6.87 MGD)

  • Fundamental full-scale study by University of Armed Forces, Munich, 4 months, 2003
  • increase in biogas production of 15%
  • improved sludge dewatering of 10%

STP Meldorf, Germany (1.06 MGD)

  • Preliminary full-scale test, 3 months, 2004 2) Full-scale installation since December 2004
  • increase in VS destruction of 25%
  • increase in biogas production of 25%
  • no foam or filamentous organisms present in the anaerobic sludge digester

STP Ergolz 2, Switzerland (3.43 MGD)

  • Full-scale test, 3 months, 2004
  • increase in VS destruction of 15%
  • increase in biogas production of 25%

STP Beverungen, Germany (2.64 MGD)

  • Full-scale test, 3 months, 2004/2005
  • increase in VS destruction of 25%
  • increase in biogas production of 25%

To sum up, ultrasonication has a positive effect on sludge solubilisation, sludge volume, biogas production, flock size reduction and cells lyses. Ultrasonic pretreatment enhances the subsequent anaerobic digestion resulting in a better degradation of volatile solids and an increased production of biogas.

The use of low power ultrasound in bioreactors may present a significant improvement in cost reduction. Therefore, ultrasonic pretreatment enhances the subsequent anaerobic digestion of sewage sludge resulting in a better sludge digestion and efficient recovery of valuables.

Methods for Hydrogen Sulphide Removal from Biogas

The major contaminant in biogas is H2S which is both poisonous and corrosive, and causes significant damage to piping, equipment and instrumentation. The concentration of various components of biogas has an impact on its ultimate end use. While boilers can withstand concentrations of H2S up to 1000 ppm, and relatively low pressures, internal combustion engines operate best when H2S is maintained below 100 ppm.

The common methods for hydrogen sulphide removal from biogas are internal to the anaerobic digestion process – air/oxygen dosing to digester biogas and iron chloride dosing to digester slurry.

Biological Desulphurization

Biological desulphurization of biogas can be performed by using micro-organisms. Most of the sulphide oxidising micro-organisms belong to the family of Thiobacillus. For the microbiological oxidation of sulphide it is essential to add stoichiometric amounts of oxygen to the biogas. Depending on the concentration of hydrogen sulphide this corresponds to 2 to 6 % air in biogas.

biogas-desulphurization

The simplest method of desulphurization is the addition of oxygen or air directly into the digester or in a storage tank serving at the same time as gas holder. Thiobacilli are ubiquitous and thus systems do not require inoculation. They grow on the surface of the digestate, which offers the necessary micro-aerophilic surface and at the same time the necessary nutrients. They form yellow clusters of sulphur. Depending on the temperature, the reaction time, the amount and place of the air added the hydrogen sulphide concentration can be reduced by 95 % to less than 50 ppm.

Measures of safety have to be taken to avoid overdosing of air in case of pump failures. Biogas in air is explosive in the range of 6 to 12 %, depending on the methane content). In steel digesters without rust protection there is a small risk of corrosion at the gas/liquid interface.

Iron Chloride Dosing

Iron chloride can be fed directly to the digester slurry or to the feed substrate in a pre-storage tank. Iron chloride then reacts with produced hydrogen sulphide and form iron sulphide salt (particles). This method is extremely effective in reducing high hydrogen sulphide levels but less effective in attaining a low and stable level of hydrogen sulphide in the range of vehicle fuel demands.

In this respect the method with iron chloride dosing to digester slurry can only be regarded as a partial removal process in order to avoid corrosion in the rest of the upgrading process equipment. The method need to be complemented with a final removal down to about 10 ppm.

The investment cost for such a H2S removal process is limited since the only investment needed is a storage tank for iron chloride solution and a dosing pump. On the other hand the operational cost will be high due to the prime cost for iron chloride.

The Function of Central Heating Radiators

Regular furnace tune-ups and maintenance just before the cold weather will help maintain your furnace and your HVAC system at top condition during the winter months. There are some common tips you can follow that will help ensure your furnace runs at peak efficiency through the long cold winter months:

heating-radiator

Help ensure your furnace runs

It is suggested that all of your HVAC equipment be cleaned and maintained before winter arrives. Beginning in early fall, have all of your cooling and heating equipment checked over thoroughly. Have a professional come out and check the furnace’s blower and ducts as well. In addition to ensuring that these are running smoothly, this will also help to prevent an increase in your home’s utility bills. If there is a problem in any of these components, you’ll need to replace them before winter fully sets in.

Finally, once your furnace has been turned back on, you’ll need to check your heat exchanger and duct for leaks. If the duct is leaking, then you may need to call a professional to take care of the leak or replace it with new ductwork. If your heater is not properly vented, then there’s a good chance that mold is growing behind the burner or behind the ductwork. You may actually be causing a foul smell from your furnace. Instead of calling a furnace service technician to come out and make you a furnace filter replacement, why not do it yourself?

First, get a flashlight and inspect your furnace’s ducts for blockages or clogs. A regular flashlight with disinfectant should work just fine. Take note of any spots that seem unusual where the air flows through. The spot could be a filter or the blower, depending on which system the furnace uses. If you see any areas with a thick black stain or smell, that’s a good indicator to clean or change the filter.

Getting furnace repairs

Once the furnace is checked and cleaned, you should conduct furnace service at least once a year. If you think you can’t do it yourself, call a reputable company in your area to get the job done. The costs for getting furnace repairs will vary depending on the make and model of your furnace and even the age of it. If you have an older model, you will probably spend more money than if you have a newer one. There are different ways to save on furnace service costs, so make sure to ask a professional about any suggestions you might have.

Remember that the experts say it is important to have regular maintenance on your furnace. However, this is not something you should take for granted. It is important to remember that the malfunctioning of your furnace could be due to the fact that there is a dirty duct where the oil or air gap gets filled up and causes the furnace to work hard to push out the air. In this case, hiring the services of a skilled and experienced furnace repairman in Calgary is essential so you don’t have to worry too much about the furnace’s condition.

If the problem with the burner is due to the presence of mold and mildew on the exterior portion of the heat exchanger, you can safely clean it yourself using a disinfectant spray made of chlorine and water. The spray must be used carefully so as not to damage the internal components of the heat exchanger and the burner. You should wear protective gloves so that you don’t spray the chemicals directly into the eyes. You can spray the area in a circular motion to avoid leaving streaks. This may also help in keeping the lining of the heat exchanger clear and free from dust, which is a common cause of friction.

Cleaning of heat exchangers by furnace service technicians is often recommended by manufacturers as an additional measure to prevent loss of refrigerant gas and to keep temperatures constant. A clean line allows for easier access when maintenance is necessary and prevents potential damage to the heating system itself. The cleaning process can take place during the summer, at night, or on days when there is little else that should be done.

Central heating radiators are available in a wide variety of styles to match any decor and to meet any budget. Whether a radiator is new or old, its function should be the first thing to be considered before buying. The more that the space heated by the radiator is heated by electricity, the more efficient the unit will be. Radiators will also heat the entire room, which could be a major plus depending on your budget.

4 Simple Furnace Repair Tips

Experienced HVAC repair technicians perform furnace repair and maintenance services. They have years of experience repairing high-end furnaces, including both wood-and hybrid models. Whether you’re having trouble with your boiler or other heating device, it’s best to contact an experienced technician. They will be able to diagnose the issue, offer the most effective solution, and fix your furnace in less time than it would take you to replace it. With trained furnace repair professionals by your side, you can feel confident that they will do their best to make your heating unit run as efficiently as possible.

furnace-repair-professionals

There are several things to look out for when trying to repair your heating system. Here are the simple tips for furnace repair:

1. Proper Certifications

One of the first steps is making sure the technician has the proper certifications. In order to qualify, he must fulfill HVAC National Board Certified Qualifying Board (HVAC NSB) qualifications. As part of being certified, he must also complete a comprehensive heat installation training program and pass the state exam. When checking out prospective technicians, make sure to ask what certifications they hold and how long they’ve been doing this type of work.

2. The Right Equipment

Next, it’s important to check out the technician’s equipment. Since many HVAC services perform work using heaters, it’s important to find out what kind of equipment they’re using. Ask to see their gas tank to see if the gas is topped off. If so, it’s a good idea to wait a few hours while the technician tops off the gas. Leaving the gas in for too long can cause serious problems like leaks and possibly explosions. If you notice signs of wear or damage on the heating equipment, contact the gas company immediately.

If the furnace repair is running but not producing enough heat, there are several steps you can take to troubleshoot the issue. First, turn the power to the furnace on and check to make sure it’s actually functioning. If it’s not, then the next step is to open the furnace door safety switch. This is located directly above the furnace itself. You’ll need to unscrew the two screws that are holding it in place and pull the safety switch straight down. It’s important to note that this step doesn’t require any tools and will allow you to safely open the door.

3. Check the Filters

Next, if you find that the furnace filters are clogged, these are the repairs you’ll need to do. Remove the filter from the furnace and wipe it clean with a damp cloth. If it appears to be damaged or dirty, you may need to purchase new filters. If not, simply replace the ones you’ve removed and wipe the rest of them clean with another cloth.

4. Cool off the Blower

For the last step in furnace blower repairs, you’ll need to remove the blower and place it in an open space to allow it to cool off completely. This step is particularly important if your heating system hasn’t been running for a while and you’re afraid of overheating it again. Once the blower has cooled down completely, it can be removed from the system. Again, you’ll need to perform all of these steps one at a time in order to ensure you don’t skip any of the necessary parts.

5. Tackling Gas Leaks

One more furnace repair tip involves cleaning and repairing gas leaks and defective heat exchangers. These are especially common in older heat and air-conditioning equipment, often resulting from poorly maintained duct work and outdated insulation. Blocked ducts allow cold air to freely enter the furnace room, which then warms up the interior of the room. Warm air can create a drafty environment inside the house, causing expensive energy bills to go through the roof.

Blocked ducts are also known to cause hot spots, especially in areas where there’s not enough duct work in the house. These hot spots will typically show up as small bluish-green stains in ceilings, walls, doors, and windows.

To fix hot spots and prevent drafty drafts, you can perform a filter change on your furnaces. It’s important to note that filters should only be changed with a qualified technician, as filters can be dangerous if changed by an untrained consumer. Filters should be replaced every three to six months, depending on the size of the filter, but they should always be replaced before they become blocked with dust or grime. Furnace repair professionals can perform the proper filter change for your furnaces and can guarantee that the process is done right.

Conveyor Systems for Waste Management

Conveyor systems are an integral component of waste management and recycling operations. It works for various types of materials and transports them to different locations.  They play a vital role in the process of sorting waste material and their movements.  Mixed wastes are arranged for inspection over a conveyor, which then moves it from one end to another. While on its way items are sorted and unwanted materials are removed.

Conveyors are also used for carrying recycling materials such as wood or paper wastes to their respective grinding and process centers. Waste conveyors are manufactured with materials that do not get damaged by constant exposure to abrasives. They are also not affected by sticky or greasy liquids and dirt. Belt conveyors and chain conveyors are the most commonly used conveyors in recycling plants.

material-recovery-facility

Mostly non-powered conveyors are used in the industry. However, powered belt and roller conveyors are sometimes used for handling small products. They are typically used for pallet handling.

Conveyors are also used for moving waste materials in long streams so that they can be separated. Vibrating belts are attached which separate materials that require inspection. Waste materials and recycling industry is mostly about dealing with contaminated products and trash. Thus additional cautions are considered for the safety and environmental standards of the workers.

Types of Conveyors

Conveyors vary in shapes and dimensions according to their utility. From being installed in biomass plants, waste sorting plants, material recovery facilities, waste-to-energy plants, to being a prime component at food processing facilities, paper industry, mining, and pharmaceutics, conveyors are used everywhere.

Even at tough job-sites where transfer of materials is required across steep inclinations or large distances conveyors can ease the process. Generally, they are classified as belt conveyors and screw conveyors.

Waste_Conveyor

Screw Conveyors

Screw conveyors were invented by Archimedes and its core design hasn’t changed from its original design over these years. They can be vertical or horizontal with an entirely contained, metered space. Screw conveyors are generally used for moving dust-free movement of grains or flakes, powders, sludge, etc. They are made of galvanized metal, carbon steel, stainless steel, tapered screws, discharge chute, or in-feed hoppers.

Belt Conveyors

Belt conveyors have a wide-open frame which enables them to contain and move high loads of material over long distances. This is why they are commonly used in the mining industry and other places where heavy materials are required to be transported.  Structurally they are rugged loops that run over two or more pulleys. Additional rolls are also added in between to provide support in long belts.

Materials ranging from garbage to fine grains and powders and be carried over belt conveyors. They are also used for the movement of commercial waste including paper, plastic, or aluminum cans.

Belt material, configuration, and dimension differ according to its application. Various designs of belts are used nowadays, for example, magnetic belts, flat belts, trough belts, rubber belts, etc. Moreover, conveyors are also designed in shapes such as to carry fluids including sludge and water. Key manufacturing materials for these belts are cotton, canvas, leather, nylon, polyester, silicone, and steel. Dimension, design and materials can be easily customized depending on its application and to meet customer requirements.

Dyne Testing and its Usefulness

Dyne Testing is a technology, a method to measure surface wettability. The low surface wettability of polymer-based substrates is the sign of poor adhesion of inks, glues and coatings. Thus, to obtain the optimum amount of adhesive it is necessary to increase the surface energy of the substrate which can be done by surface treatment with either Corona or Plasma. It will result in good wetting of the material over the surface of the substrate and hence, it improves adhesion.

For the optimum adhesion, while printing, gluing, or coating the various substrates, it is necessary to obtain high surface energy which can be obtained by Dyne Testing Markers. The fluid that is present in the Dyne Testing markers is based on ISO 8296 method for measuring the surface energy of polythene film.

When the Dyne Testing Pens are being applied to the surface, the liquid will form a continues film or will form a small trail of droplets. If it is being stretched as a film for at least 3 seconds, the substrate will have a minimum surface energy of that ink value which will be expressed in mN/m (Dynes).

The exact surface energy (Dyne level) can be determined by applying a range of increasing or decreasing values of Dyne test pens thereby taking the steps to improve its condition.

The Dyne Test Pen may lose its accuracy for which there are 3 reasons:

  1. It could get contaminated with the foreign substance
  2. It could evaporate quicker than it is expected to be
  3. And the third reason is ageing, during which chemical reactions take place among the constituents.

The experts have also faced the problem with the ageing of Dyne Testing Equipment. If their hue or color density are almost past their expiration date, it is advisable to replace them as stated by experts. The lower Dyne value states that the value stated on the bottle does not match true surface tension. You must be sure that retains the substrate used for the measurements are to be kept well sealed, free from contamination, and stored under laboratory conditions.

The ideal Dyne Testing Pen should be:

  • easy to handle,
  • perfect for the quick spot checks on the production floor,
  • very easy to read,
  • no subjectivity for this type of test,
  • no wiping off necessary,
  • lasting display of result, and
  • very striking coloring.

Conclusion

The Dyne Testing Kit is based on valve tip applicator and not the magic marker type. The quick test 38 pen is our most popular product amongst all and it is available in a bright red ink. This is the quick test pen which serves to check the surface treatment of all plastic substrates.

It has a shown an effect onto the material such that a stroke of the pens leaves a full line on the material if the material’s surface energy is below 38 Dynes/cm. Also, as mentioned above if the materials surface energy is below 38 Dynes/cm, the fluid will form small drops on the surface. The fluid applied to the surface will dry within seconds; it does not need to be wiped off anymore.

4 Reasons Why Inflatable Packer is a Must Have

Non-stop operating challenges in the field of the gas, oilfield, and underground mining has led the inflatable technology to become a mainstream go-to solution for those in jobs of high-pressure drilling, borehole measurement, and tunneling. And it is none other than the inflatable packers that have been extensively catering to the niche for over three decades now. The best thing about these tools is that they easily pass through restrictions and they are extremely sturdy to stand all the extremities and challenges of their projects.

With these tools rapidly gaining the ground in almost all parts of boring, sealing and mechanical jobs, it’s probably time to take a look at what makes these testing powerhouses really an unmatched solution in the field of special civil engineering and geotechnical studies. There are a plenty of informative and reliable sources, including http://www.aardvarkpackers.com/products-list/inflatable-packers/ and others that can tell you how these tools work and benefit their users. Another designer and manufacturer is IPI who supply oil, gas, mining and research companies with packers capable of up to 20,000 psi ratings.

What is an Inflatable Packer

As the name suggests, an inflatable packer is a plug equipment that can be extended and used in a wide array of decommissioning projects more specialized in terms of hole temperature and washouts etc. These plugs are both robust and versatile in nature and can be deployed where activities like hydraulic fracturing and high-pressure permeability require an in-depth planning and execution.

It’s the pipe that makes the main body of the packer and its the outside of the pipe that can inflate multiple times its original diameter to offer the space needed for all conventional jobs like coil tubing, pumping injections, tubes, and more.

Types of Inflatable Packers

When you have a clear idea about the job, it will be easy to choose your kind of pick from a wide selection of packers. They are many types, though…

  1. Fixed end packers
  2. Single or sliding end packers available in three styles, non reinforced, partially reinforced or fully reinforced
  3. Inward Inflating Packers ( applications include blow out preventers for mineral drilling rigs for a fraction of the cost of oilfield versions)
  4. Steel fortified
  5. Wire-line packers
  6. Custom packers (metal or other combinations)

Remember, every job needs an inflatable tool that can serve the bespoke purpose.

Uses of Inflatable Packers

As already mentioned earlier, inflatable packers are used in a wide range of energy-optimized fields, including groundwater projects, dewatering, high-pressure mining, contamination, block caving, core drilling, rock blasting and other kinds of stress testing

However, below mentioned is a list of broad range applications where these inflated tools are hugely deployed…

  1. Multi-depth ground consolidation
  2. Unconsolidated material consolidation
  3. Solid rock consolidation
  4. Improvement of mechanical properties
  5. Underground soil injections
  6. Lifting injections
  7. Sealing projects
  8. Injections in foundations
  9. Permeability testing as part of wireline coring
  10. Monitoring wells – isolation of gauges
  11. Hydraulic fracturing for rock stress testing, block caving or rock burst mitigation
  12. Swaging slim line patches to repair well casing

So, now that you know about most of the high-key projects where packers are used, there are certain unique features that make a packer ideal for a job.

  1. Extension capability of the packer’s hose,
  2. High-pressure rating
  3. The interior measurement of the pipe
  4. The exterior measurement of the pipe
  5. Length of the sealing section that complies with the uneven borehole

The real advantage of having an inflated tool with an increased number of features is that it will make sure you can use it in multifaceted projects.

Advantages of inflatable packers

There are four main reasons that make these tools a must-have. They are as follows:

  1. Inflatable packers are reusable

Yes, most of their parts can be used for a great number of times. All the parts from a mandrel, inflation point, rubber element to connectors are exchangeable and their models are available in different lengths.

  1. Material parts are built sturdy

A non-welded packer is made robust and its patented and reinforcing ribs offer a tighter grip in the target areas to withstand challenges and vulnerabilities during and post inflation. What’s more, the packer ensures a uniform inflation between its metal ribs to offer maximum efficiency at disposal operations.

  1. Good use in inconsistent contact pressure

The packer’s metal ribs offer reinforcing anchoring in the end subs. This allows the inflatable tool to optimize its pressure differential holding capacity in varying depths.

  1. Flawless and safe sealing

While the ribs and the high-quality threads of an inflatable packer offer a greater surface preparation, eliminating any need for using crossover sub, welding or epoxy, the larger expansion range of a packer’s valve system provides an extra room for the fluid and the sealing functions, What’s more, all its material tubes and check valves can be cleaned easily when you separate them.

But the benefits of using these tools don’t end just here. There are a tall-list of other advantages too when you buy a packer of this type.

Final Thoughts

In a nutshell, inflatable packers prove extremely efficient where a perfect decommissioning job can add hundreds of thousands of dollars to the ever-flourishing energy industry. Their proven track records make them a must-have for projects like test injections, geological boring, water pressure control and special cases like plugging and abandoning wells just to name a few. The good news is, nowadays these tools are made available just a click away. Just go through the specifications carefully and pick the one that best suits your niche.

Biomass Gasification Power Systems

Biomass gasification power systems have followed two divergent pathways, which are a function of the scale of operations. At sizes much less than 1MW, the preferred technology combination today is a moving bed gasifier and ICE combination, while at scales much larger than 10 MW, the combination is of a fluidized bed gasifier and a gas turbine.

biomass-gasifier

Larger scale units than 25 MW would justify the use of a combined cycle, as is the practice with natural gas-fired gas turbine stations. In the future it is anticipated that extremely efficient gasification based power systems would be based on a combined cycle that incorporates a fuel cell, gas turbine  and possibly a Rankine bottoming cycle.

Integrated Gasification Combined Cycle

The most attractive means of utilising a biomass gasifier for power generation is to integrate the gasification process into a gas turbine combined cycle power plant. This will normally require a gasifier capable of producing a gas with heat content close to 19 MJ/Nm3. A close integration of the two parts of the plant can lead to significant efficiency gains.

The syngas from the gasifier must first be cleaned to remove impurities such as alkali metals that might damage the gas turbine. The clean gas is fed into the combustor of the gas turbine where it is burned, generating a flow of hot gas which drives the turbine, generating electricity.

Hot exhaust gases from the turbine are then utilised to generate steam in a heat recovery steam generator. The steam drives a steam turbine, producing more power. Low grade waste heat from the steam generator exhaust can be used within the plant, to dry the biomass fuel before it is fed into the gasifier or to preheat the fuel before entry into the gasifier reactor vessel.

Schematic of integrated biomass gasification combined cycle

The gas-fired combined cycle power plant has become one of the most popular configurations for power generation in regions of the world where natural gas is available. The integration of a combined cycle power plant with a coal gasifier is now considered a potentially attractive means of burning coal cleanly in the future.

Biomass Fuel Cell Power Plant

Another potential use for the combustible gas from a biomass gasification plant is as fuel for a fuel cell power plant. Modern high temperature fuel cells are capable of operating with hydrogen, methane and carbon monoxide. Thus product gas from a biomass gasifier could become a suitable fuel.

As with the integrated biomass gasification combined cycle plant, a fuel cell plant would offer high efficiency. A future high temperature fuel cell burning biomass might be able to achieve greater than 50% efficiency.

Top 3 Reasons Why You Should Have a Dehumidifier at Home

Air quality is one of those things that many homeowners frequently overlook. We assume that the air indoors is better or less polluted than the air outdoors because we’re not dealing with things like car fumes and pollution.

However, your indoor air can be just as bad as the atmosphere outdoors, particularly when you have problems with humidity. Too much humidity in your air can increase the risk of things like respiratory problems, mould, and even an overflow of dust. Here are 3 reasons to consider bringing a dehumidifier into your property.

1. They Combat Mould, Mildew and Dust

Damp in your home caused by humidity can lead to mould and mildew. Often, these problems are the root cause of health issues, such as asthma, respiratory conditions, and asthma. What’s more, constant exposure to mildew and mould may even increase your chances of nervous system disorders.

Taking steps to avoid your risk of moisture build-up by keeping your sewer line clear and fixing leaky pipes is great. However, homeowners can consistently keep their risk to a minimum by investing in a dehumidifier. These crucial tools remove the extra unnecessary moisture from the air, so that it can no longer feed mould spores in your home.

Having a dehumidifier can also help you to get rid of other pesky substances like dust on your mattresses, bedspreads, and other furniture too. That’s because it’s easier for dust to cling to your surfaces when there’s moisture in the air. When the air is dry, regularly vacuuming your home will get rid of a larger portion of dust, keeping the risk of allergy to a minimum. Dehumidifiers even eliminate the risk of dust mites by keeping humidity levels at a inhospitable level for those critters.

2. They Reduce Damp and Condensation

Too much humidity in your home causes a “damp” atmosphere. When the air is moist, the most obvious result is discomfort. You might notice that your breathing feels more laboured just because you’re breathing moisture-laden air. Damp doesn’t just stay in the air however, when it reaches excessive levels, it also begins to build up on the surfaces around your home, particularly in the winter when the cold of the outdoors interacts with the warm humidity indoors.

Humidity causes long-term damage to your woodwork and soft furnishings through damp and condensation. Although it’s common to have condensation in your home from time to time, humidity exacerbates it to dangerous levels, potentially causing peeling wall papers, shrinking wood, and stains on your sofas and curtains.

A dehumidifier will reduce the moisture in the air to reasonable levels again, protecting your belongings and your comfort.

3. They Improve Air Quality for Better Health

Finally, the most important reason to invest in a dehumidifier is that they allow you to improve your air quality and eliminate common health problems. Humidity in your home can lead to an increased risk of respiratory conditions, allergens, and even problems with coughs and stuffy noses. As mould and mildew begin to build up, the effects on your health grow even greater.

Placing a dehumidifier into your home does more than just get rid of musty smells throughout your property. It also absorbs the excess moisture that could be harming your health over time. Remember, the quality of the air in your home isn’t just measured by the amount of toxins that you could be exposed to. Your air quality also depends on the level of humidity in the air too.

Dry air is less likely to feed the bacteria in the atmosphere, reducing your risk of catching bugs and respiratory illnesses. According to studies, dehumidifiers are even useful in preventing asthma attacks because they remove asthma triggers like dust mites, mould, VOCs and building wastes.

Should You Get a Dehumidifier?

In a world where indoor air quality isn’t much better than the polluted air that we find outside, it’s important to take steps to protect yourself, your family and even your home. A dehumidifier can help you to improve the air quality that you’re exposed to every day.

By eliminating the unnecessary moisture in your home, your domestic dehumidifier will improve your quality of life, reduce the risk of mould and mildew, and even protect your health.
