Modular multi-bed PSA/VSA system

This rig is a bench-scale cyclic adsorption process to separate a gaseous mixture driven by the pressure difference between adsorption and desorption steps. The number of adsorption beds can be expanded from two to up to six to make it possible to test a variety of step configurations including light or heavy reflux, blowdown purge, and pressure equalisation. It can be operated in two separate cycles, so that a product of the first stage can be fed to a feed for the second stage. It is also possible to operate it to recover CO2 from flue gases in Vacuum Swing Adsorption mode.
