Method for controlling adsorbtion gas purification installation, comprises association of state of functioning parameter with each adsorber in that state for each section of the functioning cycle

摘要

The installation (10) consists of ten adsorbers (R1-R0) which purify hydrogen entering (1) and leaving (2). The adsorbers have valves (V) directed by a control unit (8). For each phase period of the adsorber cycle an operating state designated by a parameter is associated with each adsorber and the associations rotate automatically for subsequent phase periods. Adsorber outages attract a constant state parameter An INDEPENDANT CLAIM is also included for : An installation for gas purification by adsorbtion which uses a sequencer to produce cyclic operation with a facility for a faulty adsorber to be kept in a constant state with the remainder cycling about it to maintain production
