Simulation and analysis of vacuum pressure swing adsorption using the differential quadrature method
Computers and Chemical Engineering, 2019Abstract A lab-scale vacuum pressure swing adsorption process for oxygen production was investigated both experimentally and theoretically. The experiments were conducted with up to 91% purity and 17% recovery. A complete set of governing equations were solved and compared using the finite difference method (FDM) and differential quadrature method ...

Vacuum Pressure Swing Adsorption to Produce Polymer-Grade Propylene
Separation Science and Technology, 2010We have evaluated the Vacuum Pressure Swing Adsorption (VPSA) technology to separate propane–propylene streams to produce polymer-grade propylene. Zeolite 4A is used as kinetic adsorbent since propylene diffuses much faster than propane. A single VPSA process is able to produce propylene with purity higher than 99.6%.

Industrial Scale Propylene/Propane Separation Using Pressure Vacuum Swing Adsorption
Industrial & Engineering Chemistry Research, 2018 Conventional propylene/propane separation via distillation is capital- and energy-intensive. Pressure vacuum swing adsorption (PVSA) is a potential low-cost alternative to C3 distillation.

Purification of coal mine methane on carbon molecular sieve by vacuum pressure swing adsorption
Separation Science and Technology, 2016ABSTRACTThe vacuum pressure swing adsorption (VPSA) method, as an alternative way to separate the CH4/N2 mixture, was adopted to purify methane from coal mine methane. The performance of the VPSA process was investigated experimentally and theoretically with a reactivated carbon molecule sieve as the adsorbent.

Vacuum pressure swing adsorption process for coalbed methane enrichment
Chinese Journal of Chemical Engineering, 2021Abstract The enrichment of low concentration coalbed methane using adsorption process with activated carbon adsorbent was studied in this work. Adsorption isotherms of methane, nitrogen and carbon dioxide on activated carbon were measured by volumetric method, meanwhile a series of breakthrough tests with single component, binary components and three
