System and method for regeneration of an absorbent solution

A system for regenerating a rich absorbent solution, said system comprising:

• an absorber facilitating interaction between a process stream and an absorbent solution, wherein said process stream comprises an acidic component, and interaction of said process stream with said absorbent solution produces a reduced acidic component stream and a rich absorbent solution;
• at least one heat exchanger accepting at least one of said reduced acidic component stream and said process stream to transfer heat to a heat transfer fluid;
• and
• at least one mechanism to transfer said heat transfer fluid from said at least one heat exchanger to a regenerator regenerating said rich absorbent solution, wherein each of said at least one mechanisms is fluidly coupled to each of said at least one heat exchangers.

An absorber for accepting a process stream, said absorber comprising:

• an internal portion comprising a top section and a lower section, wherein said lower section is below said top section;
• a process steam inlet permitting a process stream into said internal portion, wherein said process stream is contacted with an absorbent solution;
• and
• a heat exchanger, wherein said heat exchanger is located at a position internal of said absorber, a position external of said absorber, or a combination thereof.
