Abstract
EN UN PROCESO DE RECUPERACION DE UN GAS ENRIQUECIDO EN OXIGENO MEDIANTE ADSORCION DE PRESION OSCILANTE, CON UTILIZACION DE DOS ADSORBEDORES (A, B), CADA UNO ENVASADO CON UN ADSORBENTE QUE ADSORBE SELECTIVAMENTE NITROGENO A PARTIR DE UNA MEZCLA DE GASES QUE CONTIENE PRINCIPALMENTE NITROGENO Y OXIGENO, LA RECUPERACION DEL GAS ENRIQUECIDO EN OXIGENO RESTANTE SE REALIZA ENTERAMENTE MEDIANTE LA IGUALACION DE LA PRESION ENTRE LOS DOS ADSORBEDORES (A, B), Y EXISTE UNA BOMBA DE VACIO PERMANENTEMENTE CONECTADA A UNO DE LOS DOS ADSORBEDORES (A O B), PARA EVACUACION DEL NITROGENO. CON ESTE PROPOSITO, LA IGUALACION DE PRESION ENTRE AMBOS ADSORBEDORES (A, B), SE RELIZA AL MENOS EN DOS ETAPAS, DE MANERA QUE UN ADSORBEDOR (A O B) ES PRESURIZADO MIENTRAS QUE EL OTRO ES DESPRESURIZADO, DE FORMA QUE LA RECUPERACION DE GAS ENRIQUECIDO EN OXIGENO ES POSIBLE HASTA QUE NO EXISTE SUSTANCIALMENTE DIFERENCIA DE PRESION ENTRE AMBOS ABSORBEDORES (A,B).
