  • Continuous flow-through mercury cathode electrolysis cell
    Patent number: 3972793
    Abstract: A continuous flow-through mercury cathode electrolysis cell is described having a parallel anode and cathode and a non-conductive porous diaphragm separator. The cathode chamber is constructed so as to develop turbulence in the catholyte flowing therethrough to effect the maximum contact between the mercury and the catholyte solute and to promote removal therefrom of any gaseous by-products. Built-in heat exchangers provide efficient control of temperature sensitive electrolyses.
