Product Definition

The membrane chlor‑alkali process replaces traditional mercury and diaphragm cells with ion‑exchange membrane technology, allowing chlorine, caustic soda, and hydrogen to be generated from brine at lower voltages and with higher selectivity. The membranes act as selective barriers, permitting the passage of chloride ions while retaining other species, which reduces energy consumption, lowers CO₂ emissions, and yields products of superior purity.
