High pressure physical absorption regeneration process

A process for partly regenerating a first absorption solvent stream containing a given component comprising the steps of:a) contacting a feed gas stream 10 having a concentration of a given component with a lean second absorption solvent stream 36 and producing a rich second solvent stream 30 and a gas stream 12 having a lower concentration of the given component than the feed gas stream,b) heating at least part of the rich second solvent stream, and contacting it with a part of the stripping gas to produce a regenerated second solvent stream (34), andc) regenerating a loaded first absorption solvent stream 38 by contact with a further part of the gas stream 12 having a lower concentration of the given component than the feed gas stream. Advantageously the solvent regeneration process is a high pressure regeneration process that may be used with a main absorber.
