Maintenance of cryogenic air separation equipment

In the air separation unit of molecular sieve adsorption purification process, after the air is compressed at the last stage of the air compressor, the temperature out of the air compressor reaches 80-90 ℃. Since the adsorption capacity of molecular sieve is inversely proportional to the temperature, in order to improve the working efficiency of molecular sieve adsorber and ensure the purification effect, the compressed air from the air compressor must be cooled to reduce the temperature of the compressed air before entering the purification system.

  China's liquid air separation plant is widely used in metallurgy, petroleum, chemical industry, coal chemical industry, machinery, building materials and other areas of the national economy, the level of its development represents the strength of the country's economic development and also the level of industrial development, the import and export of liquid air separation plant has undergone a long journey from none to large.   Since 1956 China began to have liquid air separation ...
