Abstract

PROCEDIMIENTO PARA LA RECUPERACION DE ACRILONITRILO O METACRILONITRILO DEL EFLUENTE DE UN REACTOR DE AMOXIDACION, QUE CONTIENEN ADEMAS ACETONITRILO E IMPUREZAS ORGANICAS PESADAS. CONSISTE EN LA SEPARACION DE LOS COMPONENTES POR DESTILACION EN UN EVAPORADOR DE MUTIPLE EFECTO. EL EFLUENTE DEL REACTOR SE ENFRIA POR CONTACTO CON UN LIQUIDO ACUOSO, PRODUCIENDO UN EFLUENTE GASEOSO DE ENFRIAMIENTO QUE CONTIENE ACRILONITRILO O METACRILONITRILO Y ACETONITRILO, Y UNAS COLAS LIQUIDAS. SE SEPARA AGUA DEL LIQUIDO ACUOSO POR EVAPORACION DE MULTIPLE EFECTO ANTES DE PONER DICHO LIQUIDO EN CONTACTO CON EL EFLUENTE DEL REACTOR.
