Effect of adsorption and desorption pressure on the velocity and cycling performance of rapid pressure swing adsorption

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.

Cutting the cost of carbon capture: a case for carbon capture and utilization [PDF]

, 2016
A significant part of the cost for Carbon Capture and Storage (CCS) is related to the compression of the captured CO2 to its supercritical state, at 150 bar and typically 99% purity.

Construction and measurements of a vacuum-swing-adsorption radon-mitigation system [PDF]

, 2013
Long-lived alpha and beta emitters in the $^{222}$Rn decay chain on (and near) detector surfaces may be the limiting background in many experiments attempting to detect dark matter or neutrinoless double-beta decay, and in screening detectors.

Optimization and Recovery of a Pressure Swing Adsorption Process for the Purification and Production of Bioethanol

Fermentation, 2022
Today, there are new technologies to produce bioethanol: one of them is the Pressure Swing Adsorption (PSA) process. This process has displaced other separation technologies due to the use of natural adsorbents and its methodology to obtain high purities
