“…Over the years it has been demonstrated that PSA technology can be used in a large variety of applications: hydrogen purification [58][59][60][61][62][63][64][65][66][67][68][69][70][71][72], air separation [57,[73][74][75][76][77][78][79][80], OBOGS (on-board gas generation system) [81], CO 2 removal [82][83][84], noble gases (He, Xe, Ar) purification [85][86][87], CH 4 upgrading [31,34,37,40,42,[88][89][90][91][92][93][94][95][96], n-iso paraffin separation [5,[97][98][99]…”

Pressure swing adsorption (PSA) is a well-established gas separation technique in air separation, gas drying, and hydrogen purification separation. Recently, PSA technology has been applied in other areas like methane purification from natural and biogas and has a tremendous potential to expand its utilization. It is known that the adsorbent material employed in a PSA process is extremely important in defining its properties, but it has also been demonstrated that process engineering can improve the performance of PSA units significantly. This paper aims to provide an overview of the fundamentals of PSA process while focusing specifically on different innovative engineering approaches that contributed to continuous improvement of PSA performance.

“…Because a vacuum is normally avoided, tail-gas pressures of 0.3-0.7 kg cm À2 are typically used when high H 2 recovery is desired [8]. Usually, a multi-step, multi-column PSA process consisting of 4-12 adsorbers is used industrially [10,11]. However, the PSA model of this study is simplified to assume one PSA block through the RYield block that sets the performance of H 2 yield.…”

SUMMARYIntegrated gasification combined cycle (IGCC) technology is recognized as an alternative to conventional fossil fuel power plants for cleaner electricity generation. As well as electricity, chemical energy is also produced in the form of syngas that can be further converted into valuable chemicals such as hydrogen, dimethyl ether and synthetic fuel. This study focuses on 300 MW e scale gasification system for poly-generation of both H 2 and electricity by utilizing various feedstocks while achieving CO 2 capture using monoethanolamine absorption. The investigated feedstocks are pulverized dry coal and coal water slurry from Illinois ]6 coal, bunker-C, naphtha and bitumen. A simulation model of the gasification system is prepared with the following sub-processes: fuel preparing, gasification, ash removal, acid gas removal, water gas shift, H 2 purification process and combined cycle model simulated by ASPEN plus. The performance of the developed model is compared for each feedstock in terms of poly-generation and CO 2 capture, according to the following evaluation parameters: cold gas efficiency and carbon conversion of the gasifier, production rate of H 2 , plant net efficiency and CO 2 avoidance. Finally, sensitivity analysis is conducted on the following operating parameters of the shifted reactors for H 2 production: divergence fraction, temperature and reactor pressure.
