ABSTRACT:
A process 10 for removing acid gas components such as CO.sub.2, H.sub.2 S and/or COS from a gas stream includes feeding the gas stream into an absorption zone 54, and passing a suitable physical solvent at elevated pressure and reduced temperature counter-currently through the zone. Acid gas components are thus absorbed from the gas stream into the solvent. The absorption zone is maintained at substantially isothermal condition.
