Abstract

UN GAS DE ALIMENTACION QUE CONTIENE ETILENO PARA UN SISTEMA CRIOGENICO DE RECUPERACION DE ETILENO ES ENFRIADO Y CONDENSADO, ANTES DE SU FRACCIONAMIENTO, POR UN METODO MEJORADO QUE UTILIZA UNA COMBINACION DE UNO O MAS CONDENSADORES PARCIALES SEGUIDO POR UNO O MAS DEFLEGMADORES. EL METODO MEJORADO SIMPLIFICA EL EQUIPAMIENTO DE INTERCAMBIO DE CALOR Y REDUCE EL COSTE DE CAPITAL, Y ES PARTICULARMENTE ADECUADO PARA PROCESAR UN GAS DE ALIMENTACION PRESURIZADO PRE-REFRIGERADO PROCEDENTE DEL FRACCIONAMIENTO DEL ETANO QUE CONTIENE MENOS DE ALREDEDOR DE 1 MOL % DE PROPANO MAS PROPILENO.
