Abstract

Se describe un procedimiento de adsorción por presión variable que hace uso de al menos cuatro absorbedores, pasando los absorbedores, en adición a ciclos de adsorción y, si fuese apropiado, ciclos de expansión, a través de al menos un ciclo de barrido y siendo el gas de barrido requerido para el ciclo de barrido provisto por un adsorbedor diferentes; y una disposición de adsorción por presión variable. El número de adsorbedores que proveen gas de barrido es menos que el numero de absorbedores que pasan a través del ciclo de barrido y no existiendo al menos simultáneamente provisión externa de gas de barrido. En esta disposición, un adsorbedor que provee gas de barrido suministra preferentemente gas de barrido a al menos dos absorbedores.A variable pressure adsorption process is described which makes use of at least four absorbers, passing the absorbers, in addition to adsorption cycles and, if appropriate, expansion cycles, through at least one sweep cycle and the scanning gas required for the scanning cycle provided by a different adsorber; and a variable pressure adsorption arrangement. The number of adsorbers that provide sweeping gas is less than the number of absorbers that pass through the sweep cycle and there is no external supply of sweeping gas at least simultaneously. In this arrangement, an adsorber that provides scanning gas preferably supplies scanning gas to at least two absorbers.
