Abstract
A method of operating a multi-adsorber pressure-swing adsorber installation in which each adsorber is, in a given cycle, operated for a plurality of time slots in an adsorption stage, subjected to a plurality of pressure-relief phases over corresponding time slots by pressure equalization with other adsorbers, the pressure-relief phases are followed by purging phases and ultimately pressure buildup phases likewise by pressure equalization with other adsorbers. According to the invention, upon the detection of a pressure condition, either by direct measurement of pressure or by measurement of another parameter, deviating from a setpoint value indicating a defect in one adsorber or its valve or duct systems, this adsorber is cut out of the system and the remaining adsorbers are continued to be cycled or are temporarily retained in a previous phase with readjustment of the sequencing so that the feed and output remain continuous, the remaining adsorber sequences corresponding to the number of adsorbers which remain operative.
