Electrolytic cell including means for separating chlorine from the chlorine-electrolyte froth formed in the cell

An electrolytic cell adapted for the high current density electrolysis of brines is disclosed. The chlorine gas liberated at the anodes is caused to go to a chlorine disengaging tank where the gas is separated from the entrained anolyte, and the anolyte is returned to the cell. Additionally, by taking advantage of the gas uplift in one portion of the cell and the simultaneous return of anolyte to another portion of the cell, a rotary motion of the electrolyte is maintained in the cell. In this way a high concentration of chloride ion and a low concentration of gas are maintained in the anolyte under conditions of high current density electrolysis.
