Effect of adsorption and desorption pressure on the velocity and cycling performance of rapid pressure swing adsorption [PDF]
工程科学学报, 2016 Rapid(vacuum) pressure swing adsorption(RPSA or RVPSA) is featured by short cycle time and quick pressure change,which may lead to great variations of flow and mass and heat transfer in the adsorber.
