Abstract

PROCESO PARA SEPARAR UNA MEZCLA GASEOSA DE ALIMENTACION EN UN COMPONENTE MAS FUERTEMENTE ADSORBIBLE Y UN COMPONENTE MENOS FUERTEMENTE ADSORBIBLE EN UN PLURALIDAD DE BASES ADSORBENTES CONTENIENDO UN ADSORBENTE SELECTIVO PARA EL COMPONENTE MAS FUERTEMENTE ADSORBIBLE. SE USA DESPRESURIZACION DE CORRIENTE PARA PROPORCIONAR GAS DEPURADO Y PRESURIZACION POR COMPENSACION DE PRESION FINAL ENTRE LAS BASES SIMULTANEO CON EL AMBIENTE DE CORRIENTE Y PRESURIZACION DE ALIMENTACION CON PRESION ELEVADA, Y EVACUACION DE CONTRACORRIENTE. EL OXIGENO PUEDE SER RECUPERADO DEL AIRE A NIVELES ALTOS DE RECUPERACION Y PRODUCTIVIDAD ADSORBENTE USANDO EL PROCESO.
