Shintech Inc., a wholly owned subsidiary of Shin-Etsu Chemical Co. Ltd. of Japan, has selected HPD, a Veolia Water Solutions & Technologies company, to supply a salt crystallization plant and a caustic soda concentration system as part of the expansion of its production facility in Plaquemine, La. This is the second system of its kind supplied by HPD at this location and like the first salt plant, will utilize the largest, single-stage evaporated salt crystallizer in the world.
HPD will provide, on a design-build basis, a complete salt production plant and caustic soda evaporation system including construction, engineering, installation of major and ancillary equipment, foundations and pilings, structural steel, instrumentation, and commissioning support. At the heart of the system will be a single-stage, mechanical vapor recompression (MVR) evaporated salt crystallizer that will produce a nameplate capacity of 820,000 stpy of sodium chloride.
Shintech’s expansion will double the output in the existing highly integrated Plaquemine facility. Current production includes polyvinyl chloride (PVC) resins, 1 billion pounds per year of chlorine, 1.1 billion pounds per year of caustic soda, 1.65 billion pounds per year of vinyl chloride monomer (VCM), and 1.3 billion pounds per year of PVC.
