Abstract

UNA PARTE DEL CALOR DE VAPORIZACION, REQUERIDO PARA SEPARAR Y RECUPERAR METANOL DE AGUA DE LAVAR USADA PARA QUITAR METANOL DE UN C4 REFINADO RESULTANTE DE LA REACCION DE ISOBUTENO QUE CONTIENE HIDROCARBONOS C4 Y METANOL PARA PRODUCIR MTBE ES RECUPERADO POR CONDUCIR LA DESTILACION DE LA MEZCLA DE METANOL/AGUA A UNA PRESION DE 40 A 60 PSIG, POR LO CUAL INCREMENTAR LA TEMPERATURA DEL METANOL POR ENCIMA DE 104 A 114 C Y USAR LA REACCION EFLUYENTE DEL REACTOR MTBE PARA ENFRIAR Y CONDENSAR EL METANOL SOBRECALENTADO, DICHO REACTOR EFLUYENTE ES CORRESPONDIENTEMENTE CALENTADO ANTES DE ENTRAR DENTRO DE UNA TORRE DEBUTANIZADORA DONDE EL C4 NO REACCIONADO Y EL METANOL SON QUITADOS COMO UN PRODUCTO MTBE Y REFINADO RECUPERADO. ES ESTE REFINADO EL QUE ES LAVADO CON AGUA PARA RECUPERAR EL METANOL NO REACCIONADO, CON LA MEZCLA METANOL/AGUA SIENDO DESTILADA COMO SE HA PUESTO SUCESIVAMENTE ANTES. EN OTRO CASO UNA CORRIENTE QUE TIENE UNA TEMPERATURA MAS BAJA QUE EL METANOL SOBRECALENTADO ES EXTRAIDO DEL DEBUTANIZADOR Y USADO PARA ENFRIAR EL METANOL SOBRECALENTADO, ENTONCES LA CORRIENTE CALENTADA CORRESPONDIENTEMENTE VUELVE AL DEBUTANIZADOR.
