Open the CIPO recordAbstract From the Canadian patent
Operation of diaphragm monopolar electrolyzers for chlor-alkali electrolysis is improved by providing at least part of the anodes in their upper portion with hydrodynamic baffles able to generate a plurality of lifting and downcoming recirculation motions of the mixed anolyte-gas phase and of the anolyte separated from gas respectively. The baffles are characterized by their superior edge or overflow holes located under the free surface of the anolyte. The improvements introduced by the present invention provide a reduced cell voltage and an increase in the Faradic efficiency and in the quality of the products.
