Degassing, also known as degasification, is the removal of dissolved gases from liquids, especially water or aqueous solutions. There are numerous methods for removing gases from liquids. Gases are removed for various reasons. Chemists remove gases from solvents when the compounds they are working on are possibly air- or oxygen-sensitive ( air ...
The ends of these tubes were left open to allow air to pass through. The obstruction caused by the tubes played a role in breaking up and throwing down the tars suspended in the gas. Typically, plants using cast-iron mains and apparatus allowed 5 square feet of superficial area per 1,000 cubic feet of gas made per day.
Cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. When removing particulate matter from liquid, a hydrocyclone is used; while from gas, a gas cyclone is used. Rotational effects and gravity are used to separate mixtures of solids and fluids.
The G. G. Allen Steam Station scrubber (North Carolina) Flue-gas desulfurization ( FGD) is a set of technologies used to remove sulfur dioxide ( SO2) from exhaust flue gases of fossil-fuel power plants, and from the emissions of other sulfur oxide emitting processes such as waste incineration, petroleum refineries, cement and lime kilns.
[87] [88] An investigation by SafeWork NSW found that the gas was released from a tank used to hold process water. The workers were exposed at the end of a 3-day maintenance period. Hydrogen sulfide had built up in an upstream tank, which had been left stagnant and untreated with biocide during the maintenance period.
[16] [17] Industrial ammonia is transported in tank cars or cylinders. [18] NH 3 boils at −33.34 °C (−28.012 °F) at a pressure of one atmosphere, but the liquid can often be handled in the laboratory without external cooling. Household ammonia or ammonium hydroxide is a solution of NH 3 in water.
Diesel exhaust fluid ( DEF; also known as AUS 32 and marketed as AdBlue[ 3]) is a liquid used to reduce the amount of air pollution created by a diesel engine. Specifically, DEF is an aqueous urea solution made with 32.5% urea and 67.5% deionized water. DEF is consumed in a selective catalytic reduction (SCR) that lowers the concentration of ...
For a small amount of entrained gas in a drilling fluid, the degasser can play a major role of removing small bubbles that a liquid film has enveloped and entrapped [1].In order for it to be released and break out the air and gas such as methane, H 2 S and CO 2 from the mud to the surface, the drilling fluid must pass through a degassing technique, and it can be accomplished by the equipment ...
