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

AIP Conference Proceedings, 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.

Enrichment and Separation of Methane Gas by Vacuum Pressure Swing Adsorption [PDF]

Adsorption Science & Technology, 2021
In China, owing to the methane concentration being below 0.75%, the coal ventilation air methane (CVAM) is usually emitted directly into the atmosphere, rather than utilized, which not only causes huge waste of energy but also exerts potential hazards to
