Sodium Hydroxide Via Membrane Process Cost Analysis Sodium Hydroxide E11a

This report presents a cost analysis of Sodium Hydroxide production from sodium chloride. The process examined is a typical membrane process. In this process, an aqueous solution of sodium chloride (brine) is decomposed electrolytically in a membrane cell, producing Sodium Hydroxide and chlorine. The Sodium Hydroxide product obtained is a 50 wt% aqueous solution. Hydrogen is also generated as by-products in the process. This report was developed based essentially on the following reference(s): (1) Handbook of Chlor-Alkali Technology, 2005 (2) "Chlorine," Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Chlor-Alkali, Caustic Soda, NaOH
