  • Method for utilization of the reaction heat that occurs in the production process of 1,2-dichloroethane from ethylene in a fluidized bed reactor
    Patent number: 8552229
    Abstract: With a method for utilization of the reaction heat that occurs in the production of 1,2-dichloroethane from ethylene, by reaction with oxygen and hydrochloride (oxychlorination), in a fluidized bed reactor, with dissipation of this reaction heat through cooling pipe bundles situated within the reactor, positioned in the fluidized bed, utilization of the heat is supposed to be improved, while simultaneously reducing the size of the corresponding system elements. This is achieved in that part of the reaction heat is dissipated by heating boiler feed water, whereby the heated boiler feed water is used to heat heat sinks in the production process.
