Abstract
The invention relates to a process for separation or purification of gaseous streams by removal of acid gases using a liquid amine solution. The process involves the steps of —contacting the gaseous stream with liquid lean amine solution in at least one continuous flow stirred-tank reactor (10; 10a, 10b; 10c); —removing a sweetened gaseous flow from said continuous flow stirred-tank reactor (10); —removing rich amine from said continuous flow stirred-tank reactor (10; 10a, 10b; 10c) for regeneration; —passing rich amine solution through at least one flash tank stripper 20; 20a, 20b; 20c; —removing acid gases and vapor from said flash tank stripper 20; 20a, 20b; 20c; —removing lean amine from said flash tank stripper for recirculation to said continuous flow stirred-tank reactor (10; 10a, 10b; 10c).
