SYSTEM AND METHOD FOR REGENERATION OF AN ABSORBENT SOLUTION
First Claim
1. A system for absorbing an acidic component from a process stream, said system comprising:
- a process stream comprising an acidic component;
an absorbent solution to absorb at least a portion of said acidic component from said process stream, wherein said absorbent solution comprises an amine compound or ammonia;
an absorber comprising an internal portion, wherein said absorbent solution contacts said process stream in said internal portion of said absorber; and
a catalyst to absorb at least a portion of said acidic component from said process stream, wherein said catalyst is present in at least one of;
a section of said internal portion of said absorber, said absorbent solution, or a combination thereof.

25. A method for absorbing carbon dioxide from a process stream, said method comprising:
-
feeding a process stream comprising carbon dioxide to an absorber, said absorber comprising an internal portion; feeding an absorbent solution to said absorber, wherein said absorbent solution comprises an amine compound, ammonia, or a combination thereof; supplying a catalyst to at least one of;
a section of said internal portion of said absorber, said absorbent solution, or a combination thereof; andcontacting said process stream with said absorbent solution and said catalyst, thereby absorbing at least a portion of carbon dioxide from said process stream and producing a rich absorbent solution. - View Dependent Claims (26, 27, 28, 29, 30)
