Principles of PSA

MSC (molecular sieving carbon, see photo) has a high oxygen absorption capacity and a large difference in oxygen and nitrogen absorption speeds. Under pressure, it selectively absorbs oxygen in a very short time, enabling separation of nitrogen gas from atmospheric air. When returned to normal pressure, the absorbed oxygen is easily released, refreshing the MSC. In the PSA (pressure swing adsorption) method, two absorption towers are filled with MSC; absorption and desorption are alternately repeated in a cycle matched to the properties of the MSC, providing a continuous supply of high-purity nitrogen gas.
