Product Description

Product Description

The air separation plant separates atmospheric air into its primary components, typically nitrogen and oxygen, and sometimes also argon and other rare inert gases. The most common method for air separation is cryogenic distillation. Cryogenic air separation plants are built to provide nitrogen or oxygen and often co-produce argon. It uses mature cryogenic rectification technology. Our factory developed and designed a full-low pressure molecular sieve to purify the air and turbo expander refrigeration process to further reduce the energy consumption of small and medium sized air separation plants.

KunPeng has Air Separation Plants, Liquid Oxygen / Nitrogen Plant, PSA Oxygen/Nitrogen Generator, Medical (gas) Oxygen Plant, VPSA Oxygen / Nitrogen Generator, and so on. If there is any need, feel free to contact us.

Process Description

The air passes through the air filter, enters the air compressor, compresses to 0.7mpa in the compressor, and then enters the purifier after cooling, where the impurities such as water, carbon dioxide and acetylene in the air are removed. The purified air enters the Heat Exchanger for heat exchange with the backflow polluted nitrogen. A part of the gas is pumped into the turbine expander through the outlet of the heat exchanger, and the expansion provides a cooling source for the whole set of devices. The other gases continue to cool through the second heat exchanger and then enter the rectifying tower, where they are separated by oxygen and nitrogen. Finally, qualified liquid nitrogen is obtained from the top of the rectifying tower. After decompression by the throttle valve, the liquid air at the bottom enters the condensing evaporator at the top of the tower and the nitrogen heat exchange at the top of the rectifying tower, and then passes through the cooler, the second heat exchanger and the main heat exchanger cooling box as the regenerative purifier.
