FORBLUE™ FLEMION® Ion Exchange Membrane Reduces Energy Costs in Chlor-Alkali Processes

EXTON, Pa., December 15, 2020 – To help electrolysis plants achieve substantial energy savings in the chlor-alkali process, AGC Chemicals designed FORBLUE^™ FLEMION^® fluorinated ion exchange membranes that have a low electrical power consumption to decompose purified brine. FLEMION membranes help to maintain high electrical current efficiency, thanks to a highly specialized fluorinated carboxylic polymer layer in the membrane.

In addition to saving energy, FLEMION membranes minimize the influence of brine impurities like calcium, magnesium and especially barium and iodine. This allows the membranes to perform better and remain stable longer.

FLEMION membranes, used in the electrolyzers at electrolysis plants that decompose brine, play a key part in manufacturing caustic soda (sodium hydroxide), caustic potash (potassium hydroxide), chlorine and hydrogen-basic chemical products.

AGC also offers technical services for FLEMION ion exchange membranes including analysis of brine and raw salt as well as complete extractions from used membranes. AGC uses inductively coupled plasma to detect impurities; ion chromatography to measure sulfate, chlorate and iodine; total organic carbon to determine water and brine quality; and an auto titrator to calculate the concentration of salt in brine solutions.
