Abstract

UN PROCESO DE ABSORCION OSCILANTE DE VACIO PARA LA SEPARACION DE UNA MEZCLA DE GAS DE ALIMENTACION EN UNA COMPONENTE QUE SE PUEDE ABSORBER DE MANERA MAS FUERTE Y UN COMPONENTE QUE SE PUEDE ABSORBER DE MANERA MENOS FUERTE EN UN PROCESO QUE UTILIZA DOS BOMBAS DE VACIO (110, 112) Y TRES CAMAS ABSORBENTES (A, B, C) QUE CONTIENE UN ABSORBENTE SELECTOR DEL COMPONENTE QUE SE PUEDE ABSORBER MAS FUERTEMENTE UTILIZANDO UNA DEPRESURIZACION CONTRACORRIENTE Y UNA REPRESURIZACION DE ALIMENTACION AMBIENTE CORRIENTE A FAVOR SIMULTANEAS CON UNA IGUALACION DE LA PRESION DE UN EXTREMO DE UN PRODUCTO HASTA EL OTRO EXTREMO DEL PRODUCTO Y UN MONTAJE CON UNA MAQUINARIA CON EJE COMUN QUE PERMITE QUE LA ENERGIA DE EXPANSION CONTENIDA EN LAS CORRIENTES DE DEPRESURIZACION CONTRACORRIENTE Y DE PRESURIZACION DE ALIMENTACION CORRIENTE A FAVOR SEAN RECUPERADAS Y UTILIZADAS PARA REDUCIR EL CONSUMO DE ENERGIA DEL PROCESO EN GENERAL. TAMBIEN SE PUEDEN RECUPERAR LA ENERGIA DE EXPANSION EN LA PURGA DEL PRODUCTO Y LAS CORRIENTES DE IGUALACION DE LA PRESION. UTILIZANDO ESTE PROCESO, SE PUEDE RECUPERAR UN PRODUCTO DE OXIGENO A PARTIR DEL AIRE CON BAJO COSTE.
