HIGH PRESSURE PHYSICAL ABSORPTION PROCESS FOR USE IN CARBON CAPTURE IN ENERGY PRODUCTION PROCESSES

摘要

A process for at least partly regenerating a first absorption solvent (A) stream, at high pressure, and loaded with a dissolved gaseous component X; comprising the following steps: (a) contacting a feed gas stream with a lean second absorption solvent (B) stream thereby producing a rich second solvent (B) stream and a stripping gas stream that has a lower concentration of X than said feed gas stream; (b) heating at least part of said rich second solvent (B) stream by up to 10O °C before or during contacting it with a part of said stripping gas stream to produce a regenerated second solvent (B) stream; and (c) regenerating the loaded first solvent (A) stream by contacting this stream with a further part of said stripping gas stream to yield a regenerated first solvent (A) stream.
