Enrichment and Separation of Methane Gas by Vacuum Pressure Swing Adsorption [PDF]

Adsorption Science & Technology, 2021
In China, owing to the methane concentration being below 0.75%, the coal ventilation air methane (CVAM) is usually emitted directly into the atmosphere, rather than utilized, which not only causes huge waste of energy but also exerts potential hazards to

High purity oxygen production by pressure vacuum swing adsorption using natural zeolite

Results in Engineering, 2023
Pressure swing adsorption, which utilizes Nitrogen-selective adsorbents, is one of the well-known methods used in the design of medical oxygen concentrators. This method is applied in this work to design a smart oxygen concentrator prototype.

Studies of adsorbents and pressure/vacuum swing adsorption for co2 capture [PDF]

AIChE Journal, 2015
The capture of carbon dioxide via Pressure/Vacuum Swing Adsorption (PSA/VPSA) has been examined experimentally and mathematically. The adopted method was a two bed/four step process, known as the Skarstrom Cycle. Pelletised and calcined SBA-15 powder has been modified with a monoamine, a diamine and a triamine and has been tested in a PSA configuration.

Thermal management in vacuum pressure swing adsorption processes using phase change materials

Chemical Engineering Journal, 2023
Vacuum pressure swing adsorption (VPSA) is a mature separation process; however, given the current energy situation, further improvements in terms of process operations are required. To this end, the use of a thermal energy storage system during VPSA cycles appears promising, as the exothermic heat and endothermic heat generated by adsorption and ...

Data-driven simultaneous process optimization and adsorbent selection for vacuum pressure swing adsorption

Chemical Engineering Research and Design, 2022
Technologies for post-combustion carbon capture are essential for the reduction of greenhouse gas emissions to the atmosphere. However, they are still associated with high costs and energy consumption. Intensified processes for carbon capture have the potential to overcome these challenges due to their higher efficiency, lower capital cost, and ...

Simulation and optimization for hydrogen purification performance of vacuum pressure swing adsorption

Energy Procedia, 2019
Abstract A study was performed for hydrogen purification of multicomponent mixture (N2/CO/CO2/CH4/H2=0.007/0.012/0.17/ 0.021/0.79) by one-column VPSA with AC5-KS. The performance of the one-column VPSA process can be predicted by a heat and mass transfer model with porous media adsorption.
