Document Type and Number:
WIPO Patent Application WO/2022/096347
Kind Code:
A1
Abstract:
Method for managing a pressure swing absorption gas treatment unit (100), comprising: - at least N adsorbers (1-12) arranged in G groups (21-26) each comprising n=N/G adsorbers, each adsorber (1-12) comprising an instrumentation means; - a control device allowing the unit (100) to operate selectively according to a nominal cycle with N adsorbers and according to a downgraded cycle; - a plurality of connections for the control device to access the instrumentation means, characterized in that when a first and a second group each comprise at least one operational adsorber (1-12) and at least one faulty adsorber (6,8), the method comprises the steps of: - stopping the unit (100); - fluidically isolating the faulty adsorbers (1-12); - switching the instrumentation means of the faulty adsorber with those of the operational adsorber; - controlling the unit (100) according to the downgraded cycle.
