Understanding Membrane Operating Conditions

  • Chapter
Modern Chlor-Alkali Technology

Abstract

Operating conditions for membrane chloralkali electrolysis have been determined by experiment and experience in the more than ten years that membranes have been widely used by the industry. In that time our understanding of how membranes operate has advanced. We now can present a clear picture of why the operating conditions are what they are and describe the consequences of operation outside the recommended range.

  1. Under typical electrolysis conditions, about half the cations pass through the membrane. Only about 1 in 10 000 chloride ions and 1 in 1000 sulfate ions enter the membrane and into the caustic catholyte. See T. C.
