Deep cooling air separation equipment

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...

According to a DEAR air separation user, during the operation of a set of air separation plant that has been in operation for 5 years, it is found that under the condition that the inlet guide vane does not change, the expansion air volume of the expander gradually decreases, and the rotation speed of the expander gradually decreases, the outlet pressure of the booster end of the expander rises from 0.76MPa to 0.8MPa, the inlet temperature rises from - 110 ° C to - 95 ° C, and the working condition of the chilled water pump is poor.
