Patent ID: 8178059

Claim:
A system for supplying chlorine to and recovering chlorine from a polysilicon plant, comprising: a brine treatment system; at least one membrane cell operatively associated with the brine treatment system; a chlorine drying system operatively associated with the at least one membrane cell; a chlorine compression system operatively associated with the chlorine drying system; a hydrogen drying system operatively associated with the at least one membrane cell; a hydrogen compression system operatively associated the hydrogen drying system; a hydrogen chloride synthesis/desorption system operatively associated with the chlorine compression system and the hydrogen compression system; a hydrogen chloride liquefaction system operatively associated with the hydrogen chloride synthesis/desorption system; a liquefied hydrogen chloride storage system operatively associated with the hydrogen chloride liquefaction system; a hydrogen chloride vaporizer operatively associated at least one of the liquefied hydrogen chloride storage system and the hydrogen chloride liquefaction system; and the hydrogen chloride vaporizer in fluid communication with a reactor feed delivery system located within a polysilicon plant.
