Acid Gas Treatment - an overview | ScienceDirect Topics

The process of removing, H 2 S and CO 2, together is called “ acid gas treatment,” but sometimes the term “acid gas treatment” is used to denote removal of, H 2 S, alone, CO 2 alone, or both. Both, H 2 S and CO 2, can be very corrosive, with CO 2 forming carbonic acid, which is very corrosive in the presence of water.
