Chlor-Alkali

Passing electrical current through a sodium chloride and water solution releases chlorine gas. Three different types of process reaction vessels or cells are used: mercury, diaphragm, and membrane. Electrical power costs range from 35% to 70% of the total cost of producing chlorine. Accurate electrical monitoring of chlorine processes improve process performance, cost visibility, environmental compliance, and safety.

Process Applications

In order to obtain the electrical information needed for effective process control, a single measurement of total process current is ideal. Membrane electrolyzer processes are typically powered by one rectifier. Diaphragm and mercury electrolyzer processes are typically powered by multiple rectifiers in parallel.
