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
