Abstract

SE SUMINISTRA UN METODO DE REFRIGERACION EN UNA PLANTA DE RECUPERACION DE ETILENO MEDIANTE UN CICLO DE REFRIGERACION MIXTO DE CIRCUITO ABIERTO QUE UTILIZA COMPONENTES PRESENTES EN EL GAS DE SUMINISTRO QUE CONTIENE EL ETILENO COMO REFRIGERANTE MEZCLADO. LA REFRIGERACION ES SUMINISTRADA POR UN REFRIGERANTE MEZCLADO, SUBENFRIADO A ENTRE -175 (GRADOS) Y -225 (GRADOS) F PARA DESMETANIZAR EL CONDENSADOR DE CABEZA Y PARA EL ENFRIAMIENTO INICIAL Y LA CONDENSACION DEL GAS DE SUMINISTRO QUE CONTIENE ETILENO. PUEDE CONSEGUIRSE UNA RECUPERACION DE ETILENO DE HASTA EL 99.0% CON UN REDUCIDO CONSUMO DE ENERGIA EN COMPARACION CON LOS CICLOS DE RECUPERACION DE ETILENO CONVENCIONALES. ADEMAS, PUEDEN REALIZARSE AHORROS SIGNIFICATIVOS DE CAPITAL DEBIDO A LA SIMPLIFICACION DEL EQUIPO CON EL CICLO DE REFRIGERANTE MEZCLADO, DE CIRCUITO ABIERTO, QUE PUEDE SER REALIZADO VENTAJOSAMENTE A PRESIONES DE ENTRE 150 Y 400 PSIA.
