PROCESS WITH CONTINUOUSLY STIRRED TANK REACTOR ABSORBER AND FLASH TANK STRIPPER

摘要

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 vapour 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).
