Abstract
|
Reports
evaluation of vacuum swing adsorption (VSA) processes for the kinetic
separation of CO2/N2 from dry postcombustion flue gas on carbon molecular
sieve by performing rigorous optimization.
Researchers assessed the synthesized VSA configurations first for their ability to produce high purity of CO2 at high recovery. A one-stage heavy reflux cycle and a two-stage process with an enriching VSA followed by a polishing VSA, both operated as basic four-step cycles with light product pressurization, are able to meet the purity-recovery constraints. They optimized the configurations to minimize energy consumption and maximize productivity, and compared their energy-productivity Paretos. |
