Dow plans to build a new chlor alkali plant in Freeport, Texas using a membrane cell. The membrane-cell technology, replacing the diaphragm-cell production process, is expected to greatly decrease the production cost through efficient energy use.
Shintech, a vinyl producer, will partly invest in the chemical plant; while Dow will supply a steady amount of vinyl feedstock vinyl chloride monomer (VCM) it produces in return.
The existing chlor-alkali complex that will be replaced with the membrane cell will result in capacity to the tune of 3.6 mln tpa of chlorine and 4 mln tpa of caustic soda.
Completion of construction is expected in 2011.
