  • Publication number: 20070112233
    Abstract: Provided are an apparatus for preparing vinyl chloride including: a pyrolysis reactor in which 1,2-dichloroethane and inert solid particles are mixed to generate vinyl chloride and hydrochloric acid; a first separator receiving the vinyl chloride, hydrochloric acid, and inert solid particles from the pyrolysis reactor and separating the vinyl chloride and hydrochloric acid from the inert solid particles; and a regeneration reactor receiving the separated inert solid particles from the first separator and regenerating the inert solid particles by burning the inert solid particles in a high temperature to remove coke deposited on the inert solid particles, wherein the restoration reactor is connected to the pyrolysis reactor to resupply the restored inert solid particles to the pyrolysis reactor, and a method of preparing vinyl chloride using the same.

  • Patent number: 7132577
    Abstract: Provided is a method of inhibiting the formation of coke in an ethylene dichloride to vinyl chloride monomer pyrolysis cracker. The coke formation, which occurs during an ethylene dichloride pyrolysis reaction, is inhibited by contacting a heat-transfer surface of the cracker and a boron compound. The amount of coke generated when a coke formation-inhibiting material is used is 50% or less of that when a coke formation-inhibiting material is not used. In this case, however, the ethylene chloride conversion and the selectivity to a vinyl chloride monomer during the pyrolysis reaction are not affected. Accordingly, the efficiency of the pyrolysis cracker can be maximized.

  • Publication number: 20060127700
    Abstract: Provided is a coating film that inhibits the formation of coke in an ethylene dichloride to a vinyl chloride monomer pyrolysis cracker and a method of producing the coating film. The coke formation, which occurs during a pyrolysis reaction, is inhibited by coating a boron compound on a heat-transfer surface of the cracker. As a result, the amount of coke generated when a coke formation-inhibiting material is coated is decreased by 50% or greater than that when the coke formation-inhibiting material is not coated. In this case, however, the ethylene chloride conversion and the selectivity to a vinyl chloride monomer during the pyrolysis reaction are not affected. Accordingly, the efficiency of the pyrolysis cracker can be maximized.
