Amine gas treating, also known as amine scrubbing, gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines (commonly referred to simply as amines) to remove hydrogen sulfide (H 2 S) and carbon dioxide (CO 2) from gases. It is a common unit process used in refineries, and is also used in petrochemical plants, natural gas processing ...

Condensation scrubbing causes the pollutants to condense so that they can be easily removed. Impingementplate scrubbers force the emissions up a vertical chamber with water flowing down the sides of the chamber to trap sulfur particles. Coalfired power plants with scrubbers mostly use a wet scrubber system. Dry Scrubbers

The primary application for CO 2 scrubbing is for removal of CO 2 from the exhaust of coal and gasfired power plants. Virtually the only technology being seriously evaluated involves the use of various amines, monoethanolamine. Cold solutions of these organic compounds bind CO 2, but the binding is reversed at higher temperatures:

Abstract. ASPEN Plus simulations have been created for a CO 2 capture process based on adsorption by monoethanolamine (MEA). Three separate simulations were developed, one each for the flue gas scrubbing, recovery, and purification sections of the process. Although intended to work together, each simulation can be used and executed independently.

FGD Gypsum Production Process. Mineralogically identical to natural gypsum, FGD gypsum, or synthetic gypsum, is produced from gas captured within emission control systems at coal fired electric utilities. An emission that would compromise air quality, sulfur dioxide (SO 2) gas, is the primary contribution coal makes to FGD gypsum.

Scrubbers are an apparatus that cleans the gases passing through the smokestack of a coalburning power plant. Due to Clean Air Act regulations, most scrubbers in coal plants are used to remove sulfur emissions from coal and lessen the formation of acid rain. In this use, scrubbers are large towers in which aqueous mixtures of lime or limestone absorbers are sprayed through the emissions ...
