integrated harnessing blowdown brine in the manufacture of chlor-alkali, by combination of membrane technology process and mercury cathode.

摘要

INTEGRATED PROCEDURE FOR USE OF BRINE purges in the manufacture of chlor-alkali, by combining membrane technology AND MERCURY CATHODE. The present invention relates to a method for lessening the brine discharge, CAUSED BY THE OPERATIVE need to maintain a sulfate concentration in the brine used in the process Electrolytic chlorine production and caustic soda. THE PROCEDURE IS BASED ON THE INTERCONNECTION OF AN INSTALLATION BASED ON CELL MEMBRANE TECHNOLOGY AND OTHER TECHNOLOGY BASED mercury cell.
