International exchange of air separation equipment

  Gases obtained from coal as raw material may contain large amounts of carbonyl sulphur cos content too high (e.g. >20ppm) into the PSA small air separation unit will affect the quality of the product and the service life of the adsorbent molecular sieve. Common desulphurising agents are less effective in removing cos at room temperature, high temperature desulphurising agents (e.g. ferromanganese desulphurising agent...

Nitrogen is the main component of air in the universal pressure conversion and adsorption equipment. It is colorless, odorless, non-toxic and non-combustible gas under room temperature and atmospheric pressure, and its boiling point is-195.8 ℃, its chemical property is not active. In addition to synthetic ammonia, nitrogen is usually used as protective gas in industries such as metallurgy, chemical industry, coal, food, medicine, electron, magnetic material, transportation, heat treatment, tire, thermoelectricity, aviation, etc. Special pressure conversion nitrogen absorption equipment for petroleum and petrochemical industry chemical industry is the industry with the largest application of nitrogen air separation equipment. Currently, the most widely used one is: PVC, with a purity of 99.5% and a large flow rate. Polypropylene (PE) has a purity of 99.9% and a large flow rate. The application of nitrogen in this product is divided into two parts. One is that 99.9% nitrogen (small am...
