    摘要: The present invention generally relates to large capacity (e.g., greater than 350 tons/day O 2 ) vacuum pressure adsorption (VPSA) systems and processes that employ a single train including four beds (42, 44, 46, 48) , at least one feed compressor (36, 38) feeding two beds simultaneously at any given instant in time, and a single vacuum pump (52) . The compressor (s) and the vacuum pump can be utilized 100% of the time. Use of product quality gas for purging is avoided, with about 10-20% improvement in O 2 productivity and 5-10% reduction in capital cost expected.

    摘要: A pressure swing adsorption system including a plurality of vesse!s(1-7) having one or more layers of adsorbent material therein, a feed gas channel(ll?), a waste channel(120), and a product channel(130). The system also includes at least one parallel channel(140) connected to each of the vessels via a respective conduit with a valve(14). At least one pressure measuring device(M2) is configured to measure a pressure within the parallel channel. And a controller is provided that is configured to monitor the at least one pressure measured by the at least one pressure measuring device during a PSA cycle performed within the PSA system, in order to determine the performance of the cycle and monitor proper operation of the system.
