Electrolytic double diaphragm cell is used for displacement of acidic or basic gases from aqueous solution e.g. regeneration of diethanolamine in natural gas scrubbing units

摘要

Liquor containing dissolved/chemically reacted, acid or basic gas, e.g. from a scrubbing unit, is circulated through anode, intermediate, and cathode chambers defined by a pair of selective diaphragms in an electrolytic cell to liberate the dissolved gas.
