Life analysis of air separation equipment

1. Before hoisting, check and confirm whether the crane body, crane legs, lifting rigging and wire rope meet the safety requirements and hoisting conditions. 2. The hanging points of hoisting facilities shall be confirmed to prevent deviation and inclination; steel wire rope or sling shall be used for protection of edges and corners; sling and U-ring shall be used for lifting objects. 3. The commander shall use inter-phone for command, and special personnel shall be assigned for command, and the personnel shall stand at the position where the lifting object can be fully observed; warning isolation shall be set up in the hoisting area, and no one shall stand under the lifting object. 4. For large-scale hoisting, the hoisting safety scheme shall be formulated in combination with the company's special operation system.

  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...
