METHOD FOR TREATING AT LEAST ONE FEED GAS MIXTURE BY PRESSURE SWING ADSORPTION

摘要

The invention concerns a treatment method which consists in using a pressure swing adsorption treatment unit (16) and causing said treatment unit (16) to follow a nominal operating cycle, based on nominal operating conditions and in order to ensure minimal performances of the feed gas treatment. It further consists in providing at least a pre-programmed auxiliary operating cycle, different from the nominal cycle, and, when the operating conditions differ from the nominal conditions to the extent that the treatment unit (16) no longer achieves its minimal performances, in imposing to the treatment unit (16) to follow the or one of the auxiliary cycles.
