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.

CNC turning is a manufacturing process that uses a CNC machine to turn a workpiece on its axis. The workpiece is held in place by a chuck or collet and rotated while a tool is moved along the X and Y axes to create the desired shape.

CNC turning offers several benefits over traditional machining methods. First, it is a more efficient use of material. The workpiece is only machined where it needs to be, resulting in less waste. Second, it is a more precise process. CNC machines can produce extremely accurate results, down to the thousandth of an inch. Third, it is a faster process. CNC machines can often produce parts faster than traditional machining methods. Finally, it is a more versatile process. CNC machines can be programmed to produce parts with a wide variety of shapes and sizes.

What is CNC Turning

How Does CNC Turning Work?

The first step in CNC turning is to create a computer model for the desired part. This model can be created using CAD software or by scanning an existing part. Once the model is complete, it is saved as a computer file and imported into the CNC machine.

Selecting the material for the part is the next step. The material is loaded into the machine and the tool paths are programmed. The CNC machine then carves the part from the material. This process is monitored and adjusted as necessary to ensure accurate results.

When the part is finished, it is removed from the machine and cleaned up. It is then ready for use in manufacturing or further processing.

Types of Materials are Best Suited for CNC Turning

Materials that are well suited for CNC turning include metals, plastics, and composites. Metals such as aluminum, brass, and steel are commonly machined using CNC turning. Plastics such as acrylic and polycarbonate can also be turned on a CNC machine. Composite materials, such as fiberglass and carbon fiber, can also be machined using CNC turning.

Why Choose CNC Turning Over Other Manufacturing Methods?

Medical Waste Management in Developing Countries

  By | | , ,

Healthcare sector is growing at a very rapid pace, which in turn has led to tremendous increase in the quantity of medical waste generation in developing countries, especially by hospitals, clinics and other healthcare establishments. The quantity of healthcare waste produced in a typical developing country depends on a wide range of factors and may range from 0.5 to 2.5 kg per bed per day.

medical-waste-management

For example, India generates as much as 500 tons of biomedical wastes every day while Saudi Arabia produces more than 80 tons of healthcare waste daily. The growing amount of medical wastes is posing significant public health and environmental challenges across the world. The situation is worsened by improper disposal methods, insufficient physical resources, and lack of research on medical waste management. The urgent need of the hour is to healthcare sustainable in the real sense of the word.

Hazards of Healthcare Wastes

The greatest risk to public health and environment is posed by infectious waste (or hazardous medical waste) which constitutes around 15 – 25 percent of total healthcare waste. Infectious wastes may include items that are contaminated with body fluids such as blood and blood products, used catheters and gloves, cultures and stocks of infectious agents, wound dressings, nappies, discarded diagnostic samples, swabs, bandages, disposal medical devices, contaminated laboratory animals etc.

Improper management of healthcare wastes from hospitals, clinics and other facilities in developing nations pose occupational and public health risks to patients, health workers, waste handlers, haulers and general public. It may also lead to contamination of air, water and soil which may affect all forms of life. In addition, if waste is not disposed of properly, ragpickers may collect disposable medical equipment (particularly syringes) and to resell these materials which may cause dangerous diseases.

In some countries, there may be legal remedies for such losses. For example, Floridians in the US can go to a medical malpractice lawyer in West Palm Beach. In others, especially developing countries, it may be harder to get compensated, and disease may be spread more easily as a result.

Inadequate healthcare waste management can cause environmental pollution, growth and multiplication of vectors like insects, rodents and worms and may lead to the transmission of dangerous diseases like typhoid, cholera, hepatitis and AIDS through injuries from syringes and needles contaminated with human.

In addition to public health risks associated with poor management of biomedical waste, healthcare wastes can have deleterious impacts on water bodies, air, soil as well as biodiversity. The situation is further complicated by harsh climatic conditions in many developing nations which makes disposal of medical waste more challenging.

The predominant medical waste management method in the developing world is either small-scale incineration or landfilling. However, the WHO policy paper of 2004 and the Stockholm Convention, has stressed the need to consider the risks associated with the incineration of healthcare waste in the form of particulate matter, heavy metals, acid gases, carbon monoxide, organic compounds, pathogens etc.

In addition, leachable organic compounds, like dioxins and heavy metals, are usually present in bottom ash residues. Due to these factors, many industrialized countries are phasing out healthcare incinerators and exploring technologies that do not produce any dioxins. Countries like United States, Ireland, Portugal, Canada and Germany have completely shut down or put a moratorium on medical waste incinerators.

Alternative Medical Waste Treatment Technologies

The alternative technologies for healthcare waste disposal are steam sterilization, advanced steam sterilization, microwave treatment, dry heat sterilization, alkaline hydrolysis, biological treatment and plasma gasification.

Steam sterilization is one of the most common alternative treatment method. Steam sterilization is done in closed chambers where both heat and pressure are applied over a period of time to destroy all microorganisms that may be present in healthcare waste before landfill disposal. Among alternative systems, autoclaving has the lowest capital costs and can be used to process up to 90% of medical waste, and are easily scaled to meet the needs of any medical organization.

Advanced autoclaves or advanced steam treatment technologies combine steam treatment with vacuuming, internal mixing or fragmentation, internal shredding, drying, and compaction thus leading to as much as 90% volume reduction. Advanced steam systems have higher capital costs than standard autoclaves of the same size. However, rigorous waste segregation is important in steam sterilization in order to exclude hazardous materials and chemicals from the waste stream.

Microwave treatment is a promising technology in which treatment occurs through the introduction of moist heat and steam generated by microwave energy. A typical microwave treatment system consists of a treatment chamber into which microwave energy is directed from a microwave generator. Microwave units generally have higher capital costs than autoclaves, and can be batch or semi-continuous.

Chemical processes use disinfectants, such as lime or peracetic acid, to treat waste. Alkaline hydrolysis is a unique type of chemical process that uses heated alkali to digest tissues, pathological waste, anatomical parts, or animal carcasses in heated stainless steel tanks. Biological processes, like composting and vermicomposting, can also be used to degrade organic matter in healthcare waste such as kitchen waste and placenta.

Plasma gasification is an emerging solution for sustainable management of healthcare waste. A plasma gasifier is an oxygen-starved reactor that is operated at the very high temperatures which results in the breakdown of wastes into hydrogen, carbon monoxide, water etc. The main product of a plasma gasification plant is energy-rich syngas which can be converted into heat, electricity and liquids fuels. Inorganic components in medical wastes, like metals and glass, get converted into a glassy aggregate.

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.
