Deep cold air separation method

The site should be carefully checked for the chiller type and evaporator design pressure. It is not possible to use the water inlet as a water outlet and vice versa: the water flow switch is determined to be installed. The first start-up must be carried out under the guidance of the chiller plant manufacturer's personnel. Do not power on the chiller without permission. The installation requirements of the chiller plant are reflected in the operating instructions and the chiller plant manufactur...

The air is mainly composed of 78.03% nitrogen and 20.93% oxygen and other gases. Air separation is to cool the air to a certain low temperature firstly and liquefy it into liquid air. Reuse two liquids oxygen and nitrogen with different boiling points (At atmospheric pressure, the boiling point of oxygen is - 183.98°C and that of nitrogen is - 195.8°C), separation is carried out in an air fractionator equipped with sieve plates. The air separation column is also called distillation column. Air distillation column can be divided into single-stage distillation column and double-stage distillation column, and single-stage distillation column can only produce one kind of pure product. Two stage distillation column is used to produce high purity nitrogen and oxygen in common air separation unit.
