A system (10) for regenerating a rich absorbent solution (26), the system including: an absorber (20) facilitating interaction between a process stream (22) and an absorbent solution, wherein the process stream comprises an acidic component, and interaction of the process stream with the absorbent solution produces a reduced acidic component stream (28) and a rich absorbent solution; at least one heat exchanger accepting at least one of said reduced acidic component stream and the process stream to transfer heat to a heat transfer fluid (60); and at least one mechanism (60a) to transfer the heat transfer fluid from said at least one heat exchanger to a regenerator (34) regenerating the rich absorbent solution, wherein each of the at least one mechanisms is fluidly coupled to each of the at least one heat exchangers.
