Abstract
SE PRESENTA UN METODO PARA RECUPERAR UN CARBONATO DE ALQUILENO CICLICO, TAL COMO UN CARBONATO DE PROPILENO, A PARTIR DE UNA CORRIENTE DE ESCAPE DE UN PROCESO EN EL CUAL EL CARBONATO DE ALQUILENO CICLICO ELIMINA UN MATERIAL ORGANICO FOTORRESISTENTE DE UN SUBSTRATO. EL EFLUYENTE ES UN EFLUYENTE DE CARBONATO DE ALQUILENO CICLICO, POR EJEMPLO UN EFLUYENTE DE CARBONATO DE PROPILENO, DEL CARBONATO, AGUA Y SOLIDOS POLIMERICOS. EN EL PROCESO DE RECUPERACION EL EFLUYENTE DE CARBONATO DE ALQUILENO CICLICO ES SUMINISTRADO A UN INTERCAMBIADOR DE CALOR O EVAPORADOR (11), Y SE SEPARA EN I) AGUA Y SUBSTANCIAS VOLATILES, Y II) CARBONATO CICLICO. ESTO DESCIENDE LA CONCENTRACION DE AGUA EN EL CARBONATO DE ALQUILENO CICLICO HASTA UN NIVEL QUE ES LO SUFICIENTEMENTE BAJO PARA EVITAR SUSTANCIALMENTE LA HIDROLISIS DE CARBONATO DE ALQUILENO CICLICO EN EL CORRESPONDIENTE GLICOL. EL CARBONATO DE ALQUILENO CICLICO DE SECADO SE EVAPORA EN UN EVAPORADOR (41) PARA SEPARAR EL CARBONATO DE ALQUILENO CICLICO DE LOS MATERIALES DE ALTA EBULLICION Y LOS SOLIDOS POLIMERICOS. EL CARBONATO DE ALQUILENO CICLICO DESHIDRATADO SE SEPARA EN I) UNA FRACCION DE CARBONATO DE ALQUILENO CICLICO Y II) UNA FRACCION DE SOLIDOS FOTORRESISTENTES. LAS FRACCIONES DE MATERIALES FOTORRESISTENTES CONTIENEN UN MATERIAL FOTORESISTENTE EN EL CARBONATO DE ALQUILENO. LA FRACCION DE CARBONATO DE ALQUILENO CICLICO SE SEPARA EN UNA COLUMNA (71) EN UNA REACCION DE GLICOL DE ALQUILENO DE PRESION DE VAPOR MAS ALTA, Y UNA FRACCION DE CARBONATO DE ALQUILENO DE PRESION DE VAPOR MAS BAJA.
