Vacuum Pressure Swing Adsorption to Produce Polymer-Grade Propylene

Separation Science and Technology, 2010
We 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%.

Simulation and analysis of vacuum pressure swing adsorption using the differential quadrature method

Computers and Chemical Engineering, 2019
Abstract 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 process for coalbed methane enrichment

Chinese Journal of Chemical Engineering, 2021
Abstract 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
