Abstract
There is described a simple two compartment electrochemical cell which may be associated in multiples in parallel for electrochemically freeing alkanolamines of the heat stable salt forming anions found or formed in acid gas conditioning thermal regenerative sorbent processes using alkanolamines as sorbents for acid gases, the cell having an anion exchange membrane separating the cell into two compartments and an anode comprised of platinum or a platinum coated electroconductive metal electrode.
