Abstract
UN CICLO DE REFRIGERANTE MEZCLADO, DE CIRCUITO CERRADO SUMINISTRA UNA REFRIGERACION DE BAJO NIVEL, EFICIENTE PARA LA RECUPERACION DEL ETILENO DE UN SUMINISTRO DE GAS MEZCLADO. EL VAPOR DE REFRIGERANTE MEZCLADO, COMPRIMIDO SE CONDENSA ENTRE -20 (GRADOS) F Y -50 (GRADOS) F Y SE SUBREFRIGERA HASTA ENTRE -175 (GRADOS) F Y -225 (GRADOS) F MEDIANTE INTERCAMBIO DE CALOR INDIRECTO CON H2 FRIO, METANO, Y CORRIENTES EXPANSORAS A PARTIR DE CUALQUIER LUGAR EN LA PLANTA DE ETILENO. UNA PARTE DEL REFRIGERANTE SUBENFRIADO PUEDE SER PROYECTADA SUBITAMENTE PARA SUMINISTRAR UN SUBENFRIAMIENTO ADICIONAL DE LA CORRIENTE DE REFRIGERANTE MEZCLADO PRINCIPAL. EL REFRIGERANTE MEZCLADO, SUBENFRIADO ES PROYECTADO SUBITAMENTE DE FORMA SUBSECUENTE PARA SUMINISTRAR UNA REFRIGERACION DE NIVEL DE TEMPERATURA MUY BAJA PARA LA CONDENSACION DE LA CORRIENTE DE SUMINISTRO Y PARA ELIMINAR EL METANO DE LOS CICLOS DEL CONDENSADOR DE CABEZA. LA INVENCION PERMITE UN FUNCIONAMIENTO VENTAJOSO DEL TREN DE ENFRIAMIENTO DE LA CORRIENTEDE SUMINISTRO A PRESIONES DE ENTRE 150 Y 400 PSIA.
