Low Concentration Coal Mine Methane Concentrated by Vacuum Pressure Swing Adsorption
2010 International Conference on Digital Manufacturing & Automation, 2010In order to solve the current situation that low-concentration oxygen-bearing coal mine methane can’t be concentrated and utilized, the vacuum pressure swing adsorption process was employed to concentrate the oxygen-bearing coal mine methane gas with the methane concentration of 20%.

Vacuum pressure swing adsorption system for N2/CH4 separation under uncertainty
Chemical Engineering Research and Design, 2019Abstract This work presents a detailed study for the systematic design and analysis of effective VPSA process control for the separation of methane–nitrogen mixture. A rigorous mathematic model of VPSA process was developed in prior to simulate the real VPSA process and to reflect its cyclic dynamic behaviours more exactly.

Four-Bed Vacuum Pressure Swing Adsorption Process for Propylene/Propane Separation
Industrial & Engineering Chemistry Research, 2005A vacuum pressure swing adsorption (VPSA) using zeolite 5A was studied experimentally and theoretically. An equimolar mixture of propylene/propane was used as a feed gas for an eight-step, four-bed VPSA process. Isotherm data of zeolite 5A at various temperatures and breakthrough curves of propylene and propane for both adsorption and regeneration ...

Propylene/propane separation by vacuum swing adsorption using Cu-BTC spheres
Separation and Purification Technology, 2012Abstract Cu-BTC MOF is an appealing candidate to carry out propane/propylene separation by adsorption due to its high adsorption capacity and propylene selectivity. In this work a new sample of Cu-BTC, synthesised and shaped into spheres by the Korean Research Institute of Chemical Technology (KRICT) is studied for this commitment.

Simulation of a Fractionated Vacuum Swing Adsorption Process for Air Separation
Separation Science and Technology, 1998ABSTRACT A fractionated vacuum swing adsorption process previously proposed in the literature that simultaneously produces a 98% nitrogen-enriched gas and a 90% oxygen-enriched gas from ambient air is studied by simulation. This process utilizes CaX zeolite as the major adsorbent and alumina as the desiccant packed at the feed air end.

Propylene Enrichment via Kinetic Vacuum Pressure Swing Adsorption Using ZIF-8 Fiber Sorbents
ACS Applied Materials & Interfaces, 2018This work presents the synthesis, characterization, and implementation of ZIF-8/cellulose acetate fiber sorbents for the cyclic kinetic adsorption separation of an equimolar propane/propylene feed. These fiber sorbents are packed as structured mass-transfer contactors and employed in a two-bed vacuum pressure swing adsorption cycle without propylene ...
