Cryogenic O2/N2/Ar plants

Product Details
Cryogenic oxygen plant ASU can generate only oxygen, or generate both oxygen and nitrogen in gas or liquid form. The working principle of it is that dry saturated air with purifications to remove moisture, impurities entering the lower tower becomes liquid air as it continues to be cryogenic. Physically air is separated, and high purities oxygen and nitrogen are obtained by rectifying in fractionating column according to different boiling points of them. Rectifying is the process of multiple partial evaporation and multiple partial condensation.
This kind of cryogenic oxygen plant has main components including rectifying tower or cooling tower, air compressor, pre-cooler, turbine expander etc.
ADVANTAGES:
-Big production capability with scale economy.
-Stable gas performances of high quality.
-Less average unit energy consumption.
-High purity gas available.
-Full low pressure positive flow expansion process is adopted, to greatly improve the stability, safety and reliability.
-Design parameters are simulated and calculated many times by software ASPEN to ensure the rationality of the parameters.
-The fractionation column of aluminum sieve tray column greatly improves the efficiency of tray rectification.
-Stress analysis is done for pipelines in the tower, pipeline layout adopting self-compensation form.
-Aluminum welding structure is adopted for the cold valves of cold tower, to reduce the possibility of a large amount leakage.
