Abstract

PROCEDIMIENTO PARA RECUPERAR OXIDO DE ETILENO A PARTIR DE SOLUCIONES ACUOSAS, ESPECIALMENTE LAS FORMADAS POR LA PUESTA EN CONTACTO DEL EFLUENTE GASEOSO DE LA OXIDACION CATALITICA EN FASE VAPOR DE ETILENO CON CORRIENTES ACUOSAS DE RECIRCULACION. SE PONE EN CONTACTO UN DISOLVENTE EN EL ESTADO SUPERCRITICO O CASI CRITICO, TAL COMO DIOXIDO DE CARBONO A UNA TEMPERATURA DE 0-100 C Y A UNA PRESION DE 35-300 KG/CM , CON UNA SOLUCION ACUOSA QUE CONTIENE DE 0,1 A 10 MOLES% DE OXIDO DE ETILENO. SE SEPARA FISICAMENTE DE LA SOLUCION ACUOSA AGOTADA EL DIOXIDO DE CARBONO RICO EN OXIDO DE ETILENO Y, A PARTIR DE ESTE, SE RECUPERA EL OXIDO DE ETILENO REDUCIENDO LA PRESION A 30-75 KG/CM Y DESTILANDO EL DIOXIDO DE CARBONO.
