A process for the recuperation of alkanolamines from their heat-resistant salts formed in the alkanol amine absorption solutions.

摘要

There is described a simple two compartments 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 includes an anion exchange membrane separating the cell into two compartments and an anode comprised of an iridium coated electroconductive metal electrode.
