    摘要： The present invention relates generally to processes and systems for recovering helium from low helium-containing feed gases (i.e., containing less than about 10 volume % helium and more typically, less than about 5 % helium by volume). The present invention more particularly relates to processes and systems for recovering helium from low helium-containing feed gases using temperature swing adsorption (TSA) systems and multiple (e.g. two) stage vacuum pressure swing adsorption (VPSA) systems. In preferred embodiments of the invention, the first stage VPSA system is configured to provide regeneration gas for the TSA system, and/or the VPSA second stage tail gas is recycled to the first stage VPSA system.

    摘要： The present invention generally relates to large capacity (e.g., greater than 350 tons/day O2) 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 O2 productivity and 5-10% reduction in capital cost expected.

    摘要： Novel polybed VPSA process and system to achieve enhanced O2 recovery are disclosed. The VPSA process comprises using three or more adsorber beds; providing a continuous feed supply gas using a single feed blower to one bed, wherein at any instant during the process, two beds are in an evacuation step and only one bed is in a feed mode; and purging the adsorber beds using two purge gases of different purity. The VPSA cycle may further comprise utilizing a storage device (e.g., a packed or empty equalization tank) to capture void gases during co-current depressurization step of the VPSA cycle, which is used at a later stage for purging and repressurization of the bed. In addition, the VPSA process employs a single feed compressor and two vacuum pumps at 100% utilization. Furthermore, the use of the storage device minimizes the use of product quality gas for purging. About 10-20% improvement in O2 productivity is realized in the new VPSA process.
