Abstract

La presente invención se refiere a un procedimiento para la producción de un componente de referencia más selectivamente adsorbido, de alta pureza, de una mezcla de gas que contiene el componente de referencia y uno o más componentes secundarios menos selectivamente absorbidos utilizando una pluralidad de lechos paralelos de adsorción, el procedimiento está caracterizado porque comprende: a) extraer dicha mezcla de gas a través del extremo de alimentación de un primer lecho de adsorbente, conectando el extremo de efluente de dicho lecho al extremo de efluente de un lecho paralelo, el cual en este momento se ha evacuado, a manera de adsorber selectivamente el componente de referencia sobre el primer lecho de adsorbente, y permitir que uno o más componente secundarios pasen a través del primer lecho; b) enjuagar concurrentemente dicho primer lecho con componente de referencia de alta pureza para separar cualquier componente secundario co-adsorbido y cualquier componente secundario en los espacios intersticiales de dicho lecho; c) desorber a contracorriente el primer lecho mediante reducción de presión, en una o más etapas, a una presión inferior a la atmosférica, para recuperar un gas de enjuague para otro de la pluralidad de lechos que en este momento está sometido a la etapa (b) y un producto de componente de referencia de alta pureza; d) represurizar a contracorriente el primer lecho mediante conexión del extremo de efluente del primer lecho a su presión inferior a la atmosférica al final de la etapa (c) con el extremo de efluente de otro de la pluralidad de lechos que en ese momento está sometido a la adsorción de la eta pa (a), y (e) continuar esta serie de tapas con la pluralidad de lechos para formar un procedimiento continuo para la producción de componente de referencia de alta pureza.
