550Nm3/h Small Size Oxygen Nitrogen Production Equipment Air Separation Plants

Small Size Air Separation Unit Oxygen Nitrogen Plant

A cryogenic air separation plant is a complex industrial facility that separates the components of air (mainly nitrogen, oxygen, and argon) from each other by cooling the air to very low temperatures (-196°C) and then boiling off the different gases at their respective boiling points. The plant mainly consists of air compressor, purification unit, heat exchanger, distillation columns, and cryogenic storage tanks. The separation of air components has a variety of uses in industries such as chemical, petroleum, pharmaceutical, and steel production.

Liquid air separation plant pioneers the trend of future development. Because liquid products are easy for quality control, storage and delivery. In addition, they also work with higher efficiency. Therefore, the liquid air separation unit will probably be favoured by more and more users.
