Two film theory gas absorption
WebJun 20, 2013 · Abstract CO 2 capture from exhaust gas of power plants, natural gas and refinery gas can be successfully achieved by chemical absorption with alkanolamines. CO 2 capture from exhaust gas is often obtained by absorption with monoethanolamine (MEA) which is the most frequently used solvent for this purpose. Our paper focuses on the … WebAccording to two-film theory, the possible H 2 S absorption process in UV/(NH 4 ) 2 S 2 O 8 system could be summarized as follows: (I) H 2 S in gas phase would reach to gas-liquid interface ...
