Verfahren und Anlage zur Herstellung eines gasförmigen Bestandteils aus einer gasförmigen Mischung.

摘要

Process for manufacturing a gas component in pure form by separation through adsorption from other components of a gas mixture including inter alia combustible components, of the type in which a flow of the gas mixture at a high cycle pressure is sent through an adsorbent which gives, during a production stage, at the high cycle pressure, the gaseous component which is not adsorbed, for example pure hydrogen, then, during a desorption-elution stage, a desorption gas or residual gas under a low cycle pressure, which is added, after having raised its pressure, to a network of auxiliary gas, which is available under higher pressure, the addition of the residual gas to the auxiliary gas being carried out by sending the residual gas into an ejector which operates under the effect of a driving gas normally available under high pressure.
