Part 1. Main descriptions
This plant operates on a low pressure cycle and is used to produce pure oxygen and nitrogen from air by means of cryogenic rectification. The feed air is first liquefied by the refrigeration produced by turbo-expander and then rectified for two times on the basis of the different boiling points between liquid oxygen and liquid nitrogen. As a result, oxygen at a purity of over 99.6% and nitrogen at a purity of over 99.99% can be obtained from the plant. If required, the plant can also produce liquid oxygen and liquid nitrogen partially by means of modified operation.
Part 2. The basic Principle
The basis principle of air separation is to use the different boiling points of the components of liquefied air to separate them. To this end, the air separation plant consists of the following process:
1. Filtration & Compression
2. Purification
3. Cooling Air to Liquefaction Temperature
4. Refrigeration
5. Liquefaction
6. Rectification
7. Hazardous Substance Removal
