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. Un proceso para producir monomero de cloruro de vinilo a partir de etano teniendo entrada de cantidades significativas tanto de etaho como de etileno en las corrientes de entrada al reactor afiliado donde el acido clorhidrico en el efluente del reactor se hace reaccionar en una segunda reaccion despues de la reaccion de etanoletileno en vinilo. Se presentan los pasos de: reaccion catalitica de oxideshidro-cloracion del etano, etileno, acido clorhidrico, oxigeno y cloro; enfriamiento de la corriente del efluente del reactor para proporcionar una corriente de producto crudo con acido clorhidrico sin reaccionar; separacion del producto crudo en corriente de producto de monomero de cloruro de vinilo y en una corriente de ligeros que tiene arido clorhidrico; y oxicloracion del acido clorhidrico a partir de la corriente de ligeros antes del reciclaje.
