Liquid oxygen is an important industrial gas. How to manufacture liquid oxygen

2024-10-11

Liquid Oxygen (LOX) is an important industrial gas widely used in medical, chemical, aerospace and other fields. The preparation of liquid oxygen is mainly achieved through air separation technology, and the specific process is as follows:1. Compressed airFirstly, the air in the atmosphere is sucked into the compressor for compression. This step can increase the partial pressure of each component in the air, preparing for the subsequent separation process.
