System and method for removal of an acidic component from a process stream

摘要

A system (10) for absorbing and thereby removing at least a portion of an acidic component from a process stream (20), the system including: an absorber (22) adapted to accept a process stream, wherein the absorber employs an absorbent solution to absorb an acidic component from the process stream to produce a rich absorbent solution (24) and a process stream having a reduced amount of said acidic component (20a); a regenerator (26) adapted to regenerate the rich absorbent solution, thereby producing a lean absorbent solution (28) and a semi-lean absorbent solution (30); a solution outlet (50) fluidly coupled to the regenerator to facilitate removal of at least a portion of the semi-lean absorbent solution from the regenerator; and a control mechanism (56) coupled to the solution outlet, the control mechanism adapted to control an amount of the semi-lean absorbent solution removed from the regenerator.
