摘要： This invention provides a pressure swing adsorption process for purifying a synthesis gas stream containing from 60 to 90 mole % hydrogen and impurities such as CO2, CH4, N2, and CO. The PSA process of the invention further provides a method of adsorbing substantially all of the nitrogen and other contaminants from the feed gas stream; wherein the feed stream is passed at superatmospheric pressure through a plurality of adsorbent beds and each adsorbent bed contains at least a CaX, LiA, LiX or calcium containing mixed cation zeolite having a SiO2/Al2O3 mole ratio of 2.0-2.5. Such process involves sequentially pressurizing, depressurizing, purging and repressurizing the adsorbent beds with product hydrogen, and recovering product hydrogen in purities of 99.9% or greater from the beds.

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： 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.

摘要： A PSA process involving the storage of products of various purities in segregated storage tanks for subsequent usage is disclosed. Products of increasing purities, admitted at the product end of the bed, are used during purging and repressurization steps. In addition, different composition streams collected at the feed end of the bed during the countercurrent depressurization step are admitted at the feed end of the bed, in the order of increasing product component content, during the rising pressure step(s). This cycle gives higher recovery and lower bed size factor than prior art PSA cycles.
