Abstract

LA ESTERIFICACION SE LLEVA A CABO EN UN REACTOR DE COLUMNA (14) EN QUE HAY VARIAS BANDEJAS DE ESTERIFICACION (15) QUE TIENE CADA UNA UNA RETENCION DE LIQUIDO PREDETERMINADA Y QUE CONTIENEN UNA CARGA DE UN CATALIZADOR DE ESTERIFICACION SOBRE ELLAS, EJ. UNA RESINA DE INTERCAMBIO DE IONES QUE CONTIENE GRUPOS DE -SO SUB 3H Y/O -COOH. UNA FASE LIQUIDA QUE CONTIENE EL COMPONENTE DE ACIDO CARBOXILICO, EJ. UNA MEZCLA DE ACIDO GRASO, FLUYE HACIA ABAJO DEL REACTOR DE COLUMNA DESDE UNA BANDEJA DE ESTERIFICACION A LA SIGUIENTE QUE SE ENCUENTRA ABAJO EN SENTIDO CONTRARIO A UNA CORRIENTE DE VAPOR DE ALCOHOL, EJ. VAPOR DE METANOL. UN VAPOR DE ALCOHOL RELATIVAMENTE SECO SE INYECTA (21) EN EL FONDO DEL REACTOR DE COLUMNA. EL AGUA DE LA ESTERIFICACION SE EXTRAE DE LA PARTE SUPERIOR DEL REACTOR DE COLUMNA EN LA CORRIENTE DE VAPOR (26), AL TIEMPO QUE SE RECUPERA UN PRODUCTO DE ESTER (23) DEL SUMIDERO DEL REACTOR. A MEDIDA QUE EL LIQUIDO FLUYE HACIA ABAJO DE LAS BANDEJAS SE ENCUENTRA CON UN ALCOHOL QUE ES PROGRESIVAMENTE MAS SECO Y LA REACCION DE EQUILIBRIO DE LA ESTERIFICACION ES LLEVADO MAS Y MAS HACIA UNA FORMACION DE ESTER DEL 100%. UN REACTOR DE PULIMENTACION (304) QUE ES ACTIVADO CUANDO SE DA LA FASE LIQUIDA PUEDE SEGUIR AL REACTOR DE COLUMNA, MEZCLANDOSE EL PRODUCTO QUE CONTIENE ESTER CON MAS ALCOHOL ANTES DE SER ADMITIDO EN EL REACTOR DE PULIMENTACION.
