Part Of The Air Separation Plant

The compressed air from the air compressor is pre-cooled and purified by the air pre-cooling system. After the molecular sieve removes water, carbon dioxide, hydrocarbons and other impurities, part of the air is directly sent to the upper tower of the rectification tower, and the other part is expanded After expansion and refrigeration, the machine is sent to the lower tower. In the rectification tower, after heat exchange between the rising steam and the falling liquid, high purity nitrogen can be obtained at the top of the upper tower, and high purity oxygen can be obtained at the bottom of the upper tower.
