Air compressors: The atmospheric air will be compressed by air compressors until O.5MPa-O.7MPa

Pre-cooling unit:The air will be pre-cooled by this unit until 5°C-1 O°C, and water will be separated from the air.

Purification: In this stage, the carbon dioxide, moisture and hydrocarbon will be separated from the air in this purifier.

Air expansion: The air will be expanded in this expander and produces the cold for the process.

Air Cooling: The air will be cooled by the counter-flowing gaseous oxygen, gaseous nitrogen and waste nitrogen in the main heat exchanger of the rectification column until liquefing temperature of the air.

After-cooling: In the process, the liquid oxygen and liquid nitrogen are after-cooled by the gaseous nitrogen before their being throttled.

Rectification: In the stage, the air is rectified and separated in the rectification column. Thus the product gaseous nitrogen will be gained from the top of upper column and the product gaseous oxygen will be gained at the bottom of upper column.
