  • Vinyl Chloride from Ethylene The Engineering Concepts

    Flow sheet of production of ethylene dichloride Vinyl chloride is produced from ethylene in two step process Ethylene first reacts with Chlorine to produce Ethylene dichloride The purified Ethylene dichloride undergoes selective cracking to form vinyl chlorideToday, vinyl chloride is almost exclusively manufactured by thermal cleavage (dehydrochlorination) of 1,2dichloroethane (EDC) The feedstock for the thermolysis can be obtained from two routes: 1 By the older method, addition of chlorine to 2 By the more modcrn process, oxychlorination of ethylene with hydrogen chloride and O 2 or air To 1:Production of Vinyl Chloride from Ethylene LookChemproduction of vinyl chloride by this method” (21) However, as ethylene became more plentiful in the early 50’s, commercial processes were developed to produce vinyl chloride from chlorine and ethylene via EDC, namely, the balanced ethylene route Today the balanced ethylene is responsible for well over 90% of the world’s vinylVINYL CHLORIDE PRODUCTION University of Oklahoma
