Simulation of dual Ammonia Absorption Refrigeration cycle for effective utilisation of low temperature heat source
The aim of the work is to study absorption refrigeration cycle so that low temperature heat sources can be utilised for producing refrigeration. A dual cycle, which is a combination of two separate AAR cycles, is simulated, where the evaporator of the first cycle is coupled with the condenser or absorber of the second cycle. Such a dual cycle enables utilisation of low temperature heat source. ...

Redwood City Case (In Situ Gas Thermal Remediation + C3 Technology (GTR™+C3))
The former Dry Cleaner site was located in Redwood City, California, contaminated by tetrachloroethylene (PCE). Affected soils also contained low levels of PCE degradation byproducts, such as trichloroethylene (TCE), and were presumed to have an approximate extent of 384 square feet (16’ x 24’ area) to a depth of 10 feet beneath the building. The remediation goal was driven by vapor ...

Dealing with Cavitation in Control Valves
Cavitation consists of rapid vaporization and condensation within a liquid. When local pressure falls to vapor pressure (approximately 0.25 psi / 0.018 bar absolute for cold water), vapor bubbles are formed and when these bubbles travel to an area of higher pressure, the bubbles collapse with phenomenal force and great localized stress. It is the violent collapse of these vapor bubbles near valve ...

What Humidity Challenges do Engineers Face?
When designing medical equipment, engineers can often feel like Goldilocks when it comes to humidity: there’s too much or too little—and their challenge is to make it just right. Too Much Humidity is a Frequent Problem The air (or a gas) can only hold so much water vapor. Depending on external factors like temperature and pressure, water vapor can condense and create lot of ...

Flux force condensation scrubbing
Flux force condensation scrubbing technology is used to capture fine (submicron) particulate at extremely high efficiency. It is a preferred method when using wet scrubbing to collect and control dioxins from combustion sources. As an added benefit, through the use of condensation, the water vapor plume commonly associated with a wet scrubbing system can be effectively eliminated. The overall ...

Recent degassing jobs - case study
PURGIT has recovered hundreds of tons of tank vapor. Our process takes tank vapor and recovers it by condensing the vapor to liquid that can be recycled or sold. PURGIT does not waste valuable natural resources. The PURGIT process condenses tank vapor meeting environmental regulations and the recovered condensate is available for recycling. This is the most interesting and sophisticated vapor ...

High vacuum soldering and brazing with hood furnaces
Nowadays many electronic components, for example devices used in satellites or aircraft, have to withstand challenging environments such as vacuum or extremely high temperatures. To manufacture reliable electronic components like these a connection between dissimilar materials is required. Connecting dissimilar materials This connection can be metal-to-metal or even insulator-to-metal. It has to ...

Andover Case Study (C3 Technology)
In this case study in Andover, Vapor Extraction and Refrigerated Condensation was used as a primary source removal technology to remediate high concentrations of recalcitrant chlorinated solvent compounds at the WDE Site in Minnesota. The use of Refrigerated Condensation has achieved high mass removal rates and will reduce the lifecycle costs and time of remediation. Over 6500 drums of hazardous ...

Why You May Need A Tyre Oil Plant Project Report
The conversion of biodegradable materials into oil is pretty simple. It's even easier if you have an extensive source of this base material to make use of. In landfills throughout the world, you can find literally billions of rubber tyres, none in which will certainly decompose for tens of thousands of years. Savvy inventors had the ability to create what is known as tyre oil plant, and they can ...

Vaccu.Lan for Green
You're building a 'green' science building, and some of your laboratories require vacuum support. How do you provide vacuum for those labs? You can't use an oil-sealed rotary vane vacuum pumps in the labs. The oil mist would contaminate the laboratory air, and the noise pollution makes the working environment unpleasant. The pump oil would quickly be contaminated by biological and chemical ...

Food Processing: Venturi Scrubber and Separator Cuts Steam Costs - Case Study
New Solutions to Plant Problems:Soybean extraction at Land 0 ‘ Lakes, Inc., Sheldon, IA, is an energy- intensive operation. Beans must be cleaned, properly dried, tempered, cleaned a second time, fragmented, and heat-conditioned to increase smface area and distort cell walls. On the extraction side of the process, soybean flakes are extracted by repeated countercurrent percolation of hexane ...

Scrubers with a level head
The available methods for removing pollutants from a gas stream are numerous, to say the least. A popular method, scrubbers allow users to separate gases and solids by allowing the gas to come into contact with a liquid stream. In the end, the pollutants are washed away in the effluent, and the gas exits the system to be used in later processes or to be released into the atmosphere. For many ...

Reducing entropy generation by volumetric heat transfer in a supersonic two-phase steam flow in a Laval nozzle
In a supersonic flow of pure vapour in adiabatic diffusers, under some circumstances, nucleation phenomenon occurs and consequently vapour condensation is observed. In this process, the resulted pressure rise is called the condensation shock, which causes the entropy generation. The innovation of this research is analytically modelling the volumetric heat addition to the steam flow in a 1D ...

Exergy analysis of a two-stage refrigeration cycle using two natural substitutes of HCFC22
The aim of the present paper is to carry out a detailed exergy analysis of a two-stage vapour compression cycle by calculating its components exergetic losses. The exergy equations have been developed using refrigerant thermodynamic properties computed by means of a simple model of local equations of states. The results of the exergy analysis of a two-stage refrigeration system operating between ...

Upstream Particulate Removal for Rtos on Direct-Fired Osb Dryers – How much is enough?
Abstract Since 1994 Regenerative Thermal Oxidizers (RTOs) have been applied to direct wood-fired OSB dryers for the purpose of VOC abatement. In early direct wood-fired OSB dryer applications many OSB producers felt that upstream particulate control was not necessary. However, the ash from the combustion of wood waste created a host of new operational problems for the RTO systems. This paper ...

The source and risks of mercury in the offshore industry
Oil in Gas and RocksAlmost all oil and gas is found within the tiny spaces in sedimentary rocks, mainly sandstone and coarse-grained limestone. Bedrock limestone and sandstone, even though hard, also contain lots of pores that can contain water or oil or gas and other elements. Along with the gas and oil is a mixture of sand, silt & mud. This sludgy silt mud is rich in heavier metal elements ...

How does Nafion Solve Humidity Challenges?
Nafion is a polymer that add/remove select materials, including water vapor, to a gas stream through a first order kinetic reaction (a chemical reaction). Because it’s non-porous, other molecules cannot pass through it. This unique property makes it ideal for medical applications such as removing water vapor from breath samples or adding humidity to gas samples for therapeutic purposes. ...
