PROCESS FOR VINYL CHLORIDE MANUFACTURE FROM ETHANE AND ETHYLENE WITH SECONDARY REACTIVE CONSUMPTION OF REACTOR EFFLUENT HCl

摘要

A process for producing vinyl chloride monomer from ethane having input of significant quantities of both ethane and ethylene in input streams to the affiliated reactor where hydrogen chloride in the reactor effluent is reacted away in a second reaction after the ethylene/ethane-to-vinyl reaction. Steps are presented of oxydehydro-chlorination catalytic reaction of ethane, ethylene, hydrogen chloride, oxygen, and chlorine; cooling the reactor effluent stream to provide a raw product stream with unreacted hydrogen chloride; separating the raw product into a vinyl chloride monomer product stream and a lights stream having hydrogen chloride; and oxychlorinating the hydrogen chloride from the lights stream before recycle.
