Abstract

UN PROCESO MEJORADO (PSA) PARA SEPARA AL MENOS UN PRIMER GAS NO-PREFERENCIALMENTE-ABSORBIBLE, TAL COMO UN OXIGENO Y ARGON, DE UNA MEZCLA DE GAS, COMO AIRE, QUE CONTIENE DICHO PRIMER GAS, Y UNO O MAS GASES SEGUNDOS SELECTIVAMENTE ABSROBIBLES. INCLUYE PASOS NOVEDOSOS DE ECUALIZACION SIMULTANEA Y EVACUACION SEGUIDA DE UNA ALIMENTACION SIMULTANEA Y UNA REPRESURIZACION DE EL GAS RESULTANTE DE BASES. ESTO RESULTA EN UN CICLO MAS EFICAZ Y RAPIDO CON UNA UTILIZACION AL 100% CON UN MECANISMO REDUCTOR DE PRESION, COMO UN SOPLADOR DE VACIO Y UNA REDUCCION EN EL USO ENERGETICO DE APROXIMADAMENTE EL 15%. LA INVENCION INCLUYE LA SUPERPOSICION DE VARIOS PASOS DEL CICLO PSA PARA REDUCIR EL TIEMPO DE CICLO TOTAL Y ASI MEJORAR LA PRODUCTIVIDAD.
