Abstract

EL PRESENTE INVENTO ES UN PROCESO MEJORADO PARA SEPARAR ALCOHOLES DE ETERES Y/O HIDROCARBONOS REFINADO EN UN PROCESO DE ETERIFICACION. EL ALCOHOL DE EXCESO REACTANTE QUE FORMA MEZCLAS AZEOTROPICAS CON LOS PRODUCTOS ETER Y C4-C7 REFINADOS, ES QUITADO POR PASAR LA MEZCLA AZEOTROPICA LIQUIDA SOBRE UNA MEMBRANA DE PERVAPORIZACION QUE EFECTIVAMENTE ROMPE EL AZEOTROPO Y PERMITE AL ALCOHOL CON GRAN FLUJO Y ALTA SELECTIVIDAD. EN UN PROCESO DE ETERIFICACION TIPICO, UNA O UNAS UNIDADES DE MEMBRANA DE PERVAPORIZACION PUEDEN SER COLOCADAS ADELANTE DEL PASO DE DESTILACION REFINADO/ETER, EN CONJUNCION CON EL PASO DE DESTILACION CON UNA BANDA EXTRAIDA DE LIQUIDO, DESPUES DEL PASO DE DESTILACION, O UNA COMBINACION DE ALGUNO DE LOS ANTERIORES. EL PRESENTE INVENTO TAMBIEN PROVEE UN PROCESO MEJORADO PARA SEPARAR ALCOHOLES DE ETERES Y/O HIDROCARBONOS REFINADO EN UN PROCESO DE DESCOMPOSICION DE ETER PARA LA PRODUCCION DE PRODUCTOS ISO-ALKENOS DE GRAN PUREZA. EN ESTE CASO, UNA O MAS MEMBRANAS DE PERVAPORIZACIONSON USADAS PARA RECUPERAR ALCOIHOLES DE LA DESCOMPOSICION DEL AHORRO DE PRODUCTO.
