Abstract
DONDE: a) UNA MEZCLA DE AGUA, FORMAMIDA, COMPONENTES DE ALTO PUNTO DE EBULLICION Y GASES DISUELTOS SON EXTRAIDOS POR CONDENSACION DEL PRIMER DESTILADO DE LA MEZCLA DE GAS DE PRODUCTO DESPUES DE LA DESHIDRATACION CATALITICA DE FORMAMIDA GASEOSA EN PRESENCIA DE OXIGENO, PARTE DEL AGUA Y LOS GASES DISUELTOS SON SEPARADOS DEL PRIMER DESTILADO PARA DAR UN TERCER DESTILADO QUE COMPRENDE AGUA, FORMAMIDA Y COMPONENTES DE ALTO PUNTO DE EBULLICION, Y UNA CORRIENTE DE RECICLADO CONTENIENDO FORMAMIDA ES SEPARADA DEL TERCER DESTILADO POR DESTILACION SIMPLE; Y, b) HACER RECIRCULAR LA CORRIENDE DE RECICLADO HACIA LA REACCION DE DESHIDRATACION, EN DONDE DICHA CORRIENTE CONTIENE DE 5% HASTA 50% EN PESO DE AGUA. LA DESTILACION SIMPLE SE REALIZA A UNA PRESION DE 0,0204 A 0,153 Kg/cm2 Y A UNA TEMPERATURA DE 110 A 160°C; Y LA DESHIDRATACION CATALITICA A UNA TEMPERATURA DE 400 A 600°C Y A UNA PRESION DE 0,0714 A 0,357 Kg/cm2
