Шаблон:Short description Шаблон:Unreferenced

Gas separation can refer to any of a number of techniques used to separate gases, either to give multiple products or to purify a single product.

Swing adsorption techniques

Pressure swing adsorption

Шаблон:Main Pressure swing adsorption (PSA) pressurizes and depressurizes gas around an adsorbent media to selectively adsorb certain components of a gas, allowing others to be selectively discarded.Шаблон:Clarify

Vacuum swing adsorption

Шаблон:Main Vacuum swing adsorption (VSA) uses the same principle as PSA but swings between vacuum pressures and atmospheric pressure. The two techniques may be combined and are called "vacuum pressure swing adsorption" (VPSA) in this case.Шаблон:Citation needed

Temperature swing adsorption

Temperature swing adsorption (TSA) uses a similar technique to other swing adsorption techniques but cycles temperature instead of pressure.Шаблон:Citation needed

Cryogenic distillation

Шаблон:Main Cryogenic distillation is typically only used for very high volumes because of its nonlinear cost-scale relationship, which makes the process more economical at larger scales. Because of this it is typically only used for air separation.
