Abstract
Optimum current efficiencies are attained and maintained in a membrane chlor-alkali electrolytic cell by the constant, precise control of both the brine and caustic concentrations at each membrane phase boundary. Such control requires recycling through external holding tanks wherein the concentrations are adjusted to 560 grams per liter caustic and 190 grams per liter brine. Turbulent flow of such concentrations in the cells helps maintain the optimum concentration and also decreases the diffusion layer.
