Â
The heat balance of the cryogenic air separation plant is accomplished through the refrigeration system and the heat exchange system. With the development of technology, the current heat exchangers mainly use aluminum plate-fin heat exchangers.

Â
The core of the cryogenic air separation plant, an important equipment to achieve low temperature separation. Usually, high and low pressure two-stage rectification is used. It is mainly composed of low pressure tower, medium pressure tower and condensation evaporator.
