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%.

Methane Separation from Coal Mine Methane Gas by Vacuum Pressure Swing Adsorption
Chemical Engineering Research and Design, 2003The findings were presented from laboratory investigations and computer calculations for the VPSA (vacuum pressure swing adsorption) process employed to recover methane from coal mine methane gas. The separation process of coal methane gas was carried out at temperature of 278 K under adsorption pressure equal 300 kPa abs., and desorption pressure ...

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

Layered Vacuum Pressure-Swing Adsorption for Biogas Upgrading
Industrial & Engineering Chemistry Research, 2007Biogas is an important source of renewable raw methane that can be upgraded and applied as fuel for vehicles. One of the economic limitations of the upgrading relies in the bulk separation of CO2. In a previous communication (Grande, C. A.; Rodrigues, A. E. Ind. Eng. Chem. Res.

Upgrading Biogas at Low Pressure by Vacuum Swing Adsorption
Industrial & Engineering Chemistry Research, 2014Performance of four adsorbents (three zeolites and one molecular sieve carbon) for CO2–CH4 separation from simulated biogas feed containing 42% CO2 (balance methane) is compared in a simple four step dual bed vacuum swing adsorption (VSA) cycle.

This work focuses on the optimization of cyclic adsorption processes to improve the performance of CO2 capture from flue gas, consisting of nitrogen and carbon dioxide. The adopted processes are the PSA (pressure swing adsorption) process and the FVPSA (fractionated vacuum pressure swing adsorption) process, modified from the FVSA (fractionated vacuum ...
