Panahi M. Cryogenic CO2/H2S capture technologies for remote natural gas processing

NTNU, 2011. — 42 p.
Cryogenic technologies are suitable for offshore applications processes, and operation in high pressure; small sizes compared to conventional amine absorption; less energy requirement; separation of acid gases in liquid form and high pressure; readily to be pumped to the reservoir.
