Three basic methods to separate gases

Three basic methods to separate gases

Solid adsorbents, such as zeolites and activated carbon, can be used to separate CO2 from gas mixtures. In pressure swing adsorption (PSA), the gas mixture flows through a packed bed of adsorbent at elevated pressure until the concentration of the desired gas approaches equilibrium. The bed is regenerated by reducing the pressure.
