ABSTRACT:
There is disclosed an organic amine scrubbing process for acid gas abatement of gas streams. The process comprises Donnan dialysis of an absorbent solution to separate and convert organic amine heat stable salts back to free amine absorbent using an anion exchange or neutral membrane. The organic amine absorbent may be an alkanolamine, a substituted or unsubstituted 5-7 member heterocyclic amine or any organic amine suitable for acid gas scrubbing. There is also disclosed a dialysis cell comprising a two compartment cell separated by a membrane. The cell includes a charge of an organic amine high in the organic amine heat stable salt concentration in one compartment and a charge of a base solution in the other compartment. Also disclosed is a process for abating acid gases wherein the organic amine absorbent is regenerated by Donnan dialysis, and an apparatus for effecting the regeneration.
