Abstract
The present invention generally relates to large capacity (e.g., greater than 350 tons/day O) vacuum pressure adsorption (VPSA) systems and processes that employ a single train including four beds, at least one feed compressor feeding two beds simultaneously at any given instant in time, and a single vacuum pump. 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 Oproductivity and 5-10% reduction in capital cost expected.
