摘要
Alkali metal hydroxide and acid are recovered from alkali metal salts by water-splitting. A two-compartment cell employs monovalent anion-selective membranes and bipolar membranes; a three-compartment cell (1) employs monovalent anion-selective membranes (3), cation-selective membranes (4) and bipolar membranes (2a, 2b). A particular application is the conversion of the Electrostatic Precipitator Catch of the recovery boiler of coastal and/or closed-cycle kraft pulp mill with reuse of the sodium/potassium hydroxide and sulfate, depleted in chloride.
