Determination of Current Efficiency of Diaphragm Alkali-Chlorine Cells by Gas Analysis

Abstract

A description is given of a method for determining current efficiency of an alkalichlorine plant simply by an analysis of a cumulative sample of chlorine cell gas, rather than by the more laborious method of measurement of the entire production and current input. A method of obtaining a 24-hr cumulative sample of gas at a uniform rate is described. Essentially the method of calculation is based upon the fact that the ratio of carbon dioxide and oxygen to chlorine in the cell gas depends upon the current efficiency of cell operation.
