Abstract
PURPOSE: To efficiently operate both of a sodium chlorate electrolytic tank and a chlorine-alkali eletrolytic tank by a method wherein stock salt is replenished in a dilute salt water of a cation exchange membrane process chlorine-alkali electrolytic tank and a part of a purified salt water obtained through a purifying process for removing impurities is supplied to a sodium chlorate electrolytic tank.
CONSTITUTION: To a dilute salt water of which a concn. is lowered by electrolysis in a chlorine-alkali electrolytic tank 1 divided into an anode chamber 6 and a cathode chamber 7 by a cation exchange membrane 5, water 18 and a stock salt 19 are replenished in a salt dissolving tower 17 and sent to a primary purifying apparatus 20 and a secondary purifying apparatus 21 successively. In the primary purifying apparatus 20, a chemical agent is added and, in the secondary purifying apparatus 21, a chelate ion exchange resin is added to prepar a purified salt water with a salt concn. of 270g/l or more (especially, 300W320g/l). A part of said purified salt water is supplied to a sodium chlorate electrolytic tank 2 through a stagnation tank 23 from a line 22.
