Application Range of Membrane Separation, Pressure Swing Adsorption and Cryogenic Rectification

Cas Capacity (m h- ) Typical purities Preferred separation method Load range 

The economic significance of the specific energy consumption is demonstrated by the example of a cryogenic plant for the production of 50 000 m, h of unpressurized oxygen, which is a common plant size. With a specific energy requirement of 0.35 kWh per standard cubic meter of O2 the plant needs annually 1.5 10 MWh, which, assuming an electricity price of 0.05 kW h , corresponds to operating cost of 7.7 Mio. per year.
