Gas Separation

 

separation of gas mixtures into their individual components (or fractions). Gas separation is usually preceded by the drying of gas mixtures and the removal from them of noxious impurities—for example, nitric oxides, which form dangerously explosive compounds with unsatu-rated hydrocarbons; catalytic toxins which prevent the chemical refining of gases; and hydrogen sulfide, water vapor, and several hydrocarbons, which cause corrosion of equipment or which congeal in the equipment at low temperatures.

The principal methods of gas separation are rectification of gases liquefied by deep cooling, absorption and adsorption, and fractional condensation.

Gas separation is widely used in the separation of air and gaseous hydrocarbons. New trends in gas separation technology include chromatography, extractive and azeotropic distillation, and the use of molecular screens and gas centrifuges.

Objective: Membranes offer effective solutions for a wide range of separation processes, such as desalination, water treatment, air filtering, biomolecular detection and gas separation. Despite their effectiveness versus other separation methods, the conventional membrane concept is based on either long and tortuous pores, or solution-diffusion, both limiting the permeation rates and causing fouling.
