A process for the regeneration of an acid gas absorbent comprising an amine and heat stable salts by phase separation, comprising a) mixing the acid gas absorbent with an alkaline solution, to form a mixture with a pH above the pH equivalence point of the amine; b) cooling the mixture to a temperature below 500 C; c) separating the mixture into a regenerated acid gas absorbent and a waste stream; d) collecting the regenerated acid gas absorbent separate from the waste stream.

Process for the removal of heat stable salts from acid gas absorbents

A diamine absorbent that contains heat stable salts is regenerated using an ion exchange process wherein the concentration of heat stable salts in the feed stream provided to the cation exchange unit is limited.

Method for treating a diamine absorbent stream

A diamine absorbent that contains heat stable salts is regenerated using an ion exchange process wherein the cation exchange resin is regenerated using sulfurous acid reflux.
