Abstract

This chapter presents a general overview of the processing steps in a typical chlor-alkali plant. As shown in Fig. 6.1, we can divide the process into three major steps. These are the preparation of purified brine, electrolysis, and processing of the crude products of electrolysis. The figure also subdivides brine preparation into its main elements. Later sections present flowsheets in block form for each of the process steps. A discussion of the differences among the various types of electrolyzer technology accompanies each flow diagram. Separate flowsheets for the complete processes for the three electrolyzer technologies are also available in the literature [1, 2].
