Abstract

LA PRODUCCION DE OXIDO DE ETILENO CONSISTE EN DEJAR REACCIONAR EN UN REACTOR (2) ETILENO Y UN GAS QUE CONTENGA OXIGENO LIBRE HASTA QUE SE PRODUZCA OXIDO DE ETILENO EN PRESENCIA DE METANO, ARGON Y DIOXIDO DE CARBONO; RETIRAR DEL REACTOR (2) UN EFLUENTE DEL REACTOR (4); RETIRAR (6) EL OXIDO DE ETILENO DEL EFLUENTE DEL REACTOR PARA OBTENER UNA CORRIENTE DE RECICLADO (9); RETIRAR EL DIOXIDO DE CARBONO (22) Y EL ARGON (30) DE LA CORRIENTE DE RECICLADO PARA OBTENER UNA CORRIENTE DE RECICLADO TRATADA (40) QUE SE SUMINISTRA AL REACTOR (2); Y SUMINISTRAR (42) REACTIVOS ADICIONALES Y METANO AL REACTOR (2), EN DONDE LA RETIRADA DEL ARGON CONSISTE EN SEPARAR UNA CORRIENTE SECUNDARIA (16) DE LA CORRIENTE DE RECICLADO, HACER PASAR A LA CORRIENTE SECUNDARIA (16) A UNA UNIDAD DE MEMBRANA (30), EXTRAER UNA CORRIENTE QUE CONTIENE ARGON POR LA SALIDA DE PESMEACION (32), EXTRAER UNA CORRIENTE RETENIDA POR LA SALIDA DE RETENCION (33) QUE SE AÑADE A LA CORRIENTE DE RECICLADO (40) Y PURGAR EL LADO DE PESMEACION DE LA UNIDAD DE MEMBRANA (30) CON GAS INERTE.
