Hydrogen purification is an important part of hydrogen energy utilization. This study aimed to perform multi-component gas (H2/CO2/CH4/CO/N2 = 0.79/0.17/0.021/0.012/0.007) by one-column vacuum pressure swing adsorption (VPSA) and (PSA). AC5-KS was selected as the adsorbent for due its greater capacity compared R2030. Furthermore, VPSA PSA 10-step cycle models were established simulate process u...

The complexity of chemical plant systems (CPS) makes optimising their design and operation challenging tasks. This also results in analytical numerical simulation models these having high computational costs. Research demonstrates the benefits using machine learning as surrogates or substitutes for computationally expensive during CPS optimisation. paper presents our study, extending recent res...

This study presents the adsorption performance indicator for the evaluation of thermal power plant CO2 capture on mesoporous graphene oxide/TiO2 nanocomposite. To begin, this adsorbent was synthesized and characterized using N2 adsorption-desorption measurements (BET and BJH methods), X-Ray Diffraction (XRD), Field Emission Scanning Electron Microsc...

The study's primary purpose is to simulate the adsorption and desorption of volatile organic components on activated carbon bed using python. model was verified with experiments for separation methane (55 mol %) - dioxide (45 mixture vacuum pressure swing an molecular sieve. For a six-component (methane, ethane, propane, butane, nitrogen), Aspen Adsorption flowsheet simulator experimental resul...

The adsorption isotherms of nitrogen, oxygen and argon in four VA-class hydrophobic dipeptides are presented. Isotherms were determined at 5, 20 and 35 °C, for a pressure range of 0-6 bar. Under these conditions, adsorption is still in the Henry region. For all materials and temperatures, the sequence of preferential adsorption is Ar > O2 > N2, a highly abnormal result. At 5 °C, the dipeptide w...

A novel hydrogen pressure swing adsorptionsystem has been studied that is applied to an advanced inte-grated gasification combined cycle plant for cogeneratingpower and ultrapure hydrogen (99.99? mol%) with CO2capture. In designing the H2 PSA, it is essential to increase therecovery of ultrapure hydrogen product to its maximum sincethe power consumption for compressing t...

Vacuum swing adsorption (VSA) is a promising treatment method for volatile organic compounds (VOCs). This study focuses on a VSA process for regenerating activated carbon spent with VOCs, and then investigates its adsorption capacities. Toluene was selected as the test VOC molecule, and the VSA regeneration experiments results were compared to the thermal swing adsorption (TSA) process. Cyclic ...
