Abstract

SE DESCRIBE UN PROCESO DE SEPARACION DE BUTENOS Y DE BUTANOS POR DESTILACION EXTRACTIVA. UNA CARGA QUE CONTIENE PRINCIPALMENTE BUTENOS Y BUTANOS ES PUESTA EN CONTACTO EN UNA COLUMNA DE DESTILACION EXTRACTIVA A PRESION CON UN PRIMER SOLVENTE S1, POLAR SELECTIVO (POR EJEMPLO EL DIMETILFORMAMIDA), SIENDO RECOGIDOS LOS BUTANOS EN CABEZA, EL SOLVENTE S1 QUE CONTIENE LOS BUTENOS QUE SALEN AL FINAL SE MEZCLA CON UN SEGUNDO SOLVENTE S2 DE TEMPERATURA DE EBULLICION INTERMEDIA ENTRE LA DE LOS BUTENOS Y LA DEL SOLVENTE S1, PASANDO LA MEZCLA A UNA COLUMNA DE DESORCION A PRESION DONDE LOS BUTENOS SON RECOGIDOS EN CABEZA, SE SEPARA LA MEZCLA DE LOS SOLVENTES S1 Y S2 EN UNA COLUMNA DE PURIFICACION A PRESION ATMOSFERICA, EL SOLVENTE QUE SALE EN CABEZA SE RECICLA HACIA LA COLUMNA DE DESORCION, Y EL SOLVENTE S1 QUE SALE AL FINAL SE RECICLA HACIA LA COLUMNA DE DESTILACION EXTRACTIVA. POR ESTE PROCESO QUE PRESENTA UNA MAYOR SIMPLICIDAD DE APLICACION, ES POSIBLE SEPARAR LOS BUTENOS CON UNA PUREZA DE AL MENOS APROXIMADAMENTE 97% EN PESO
