Method for the removal of heat stable amine salts from an amine absorbent

A carbon dioxide (CO2) capture system using an amine absorbent for absorption of CO2 from a gas stream, having a subsystem for the removal of heat stable amine salts from an amine absorbent, said subsystem comprising:

• a residual CO2 removal unit in liquid connection with, and configured to receive, an amine absorbent stream containing heat stable amine salts from the CO2 capture system, and operative for separating residual CO2 from said amine absorbent stream;
• and
• an amine reclaimer in liquid connection with, and configured to receive, an amine absorbent stream containing heat stable amine salts and having a reduced concentration of CO2 from the residual CO2 removal unit, and operative for separating heat stable amine salts from said amine absorbent stream.
