  • Systems and methods for supplying chlorine to and recovering chlorine from a polysilicon plant
    Patent number: 8178059
    Abstract: A system for supplying chlorine to and recovering chlorine from a polysilicon plant may include a brine treatment system, at least one membrane cell, a chlorine drying system, a chlorine compression system, a hydrogen drying system, a hydrogen compression system, a hydrogen chloride synthesis/desorption system, a hydrogen chloride liquefaction system, a liquefied hydrogen chloride storage system, a hydrogen chloride vaporizer, and a waste conversion and filtration system. These systems may be operatively joined to generate hydrogen chloride gas for delivery to the polysilicon plant. A method for supplying chlorine to the polysilicon plant may include generating hydrogen gas and chlorine gas from recovered and raw salt, converting at least a portion of the hydrogen gas and at least a portion of the chlorine gas to hydrogen chloride, passing the hydrogen chloride through a cryogenic column, vaporizing the hydrogen chloride, and providing the vaporized hydrogen chloride to the polysilicon plant.
