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.
