Deep cooling air separation system

Installation of pipes in the cold box in liquid air separation plant Stainless steel welding wire must be baked at the temperature strictly in accordance with the instructions for use and kept warm before use. Receive welding rod, welders must use the electrode insulation cylinder, and do a good job of anti-aluminium welding wire clean, dry and sealed packaging, otherwise chemical cleaning and drying treatment is required before use. Welding rod grades must be used uniformly and not mixed. Pr...

  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...
