process with continuously stirred tank reactor absorber and flash tank extraction unit

摘要

Patent specification: "Process with continuously stirred tank reactor absorber and flash tank extraction unit". The present invention relates to a process for separating or purifying gaseous streams by removing acidic gases using a liquid amine solution. The process involves the steps of: contacting the gas stream with a liquid lean amine solution in at least one continuous flow stirred tank reactor (10; 10a, 10b; 10c); removing a sweetened gas stream 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 a rich amine solution through at least one flash tank extraction unit 20; 20a, 20b; 20c; removing acid gases and vapor from said flash type evaporation tank extraction unit 20; 20a, 20b; 20c; removing lean amine from said flash type evaporation recirculation tank extraction unit for said continuous flow stirred tank reactor (10; 10a, 10b; 10c). 21423691v1
