Abstract
In this study, we have considered Pressure Swing Adsorption (PSA) technology natural gas purification and
integrated CO2 capture. We present the utilization of Dual-PSA technology for obtaining pipeline-quality methane
and integrated CO2 capture. In the initial simulation example, a binary stream of 10% CO2 – 90% CH4 could be
separated into two streams where the CH4-rich stream has a purity of 98% and the CO2-rich stream has a purity of
91%. The overall recovery of methane is higher than 99% and unit productivity of the Dual-PSA is 3.3 mol CH4
/(kgads.h).
