Abstract

PROCEDIMIENTO PARA LA SEPARACION CONTINUA DE ANHIDRIDO DE ACIDO MALEICO A PARTIR DE GASES DE PROCESO PROCEDENTES DE LA OXIDACION CATALITICA DE HIDROCARBUROS EN LA FASE DE VAPOR POR TRATAMIENTO DE LOS GASES CON UN DISOLVENTE. COMO DISOLVENTE SE EMPLEAN ESTERES DE ACIDOS CICLOALIFATICOS. EN UNA COLUMNA DE ADSORCION SE HACE CIRCULAR EL DISOLVENTE EN CONTRA DEL GAS DEL PROCESO; ESTE DISOLVENTE CONTIENE DE UN 10 A 30 POR 100 DE ANHIDRIDO DE ACIDO MALEICO Y SE APORTA ESCALONADAMENTE O EN CONTINUO A UNA DESTILACION FRACCIONADA. ESTE ANHIDRIDO ES SEPARADO POR DESTILACION Y LOS DISOLVENTES DE ALTO PUNTO DE EBULLICION SE APORTAN NUEVAMENTE A LA COLUMNA DE ADSORCION.
