The leakage of unit or pipeline in the cold box needs removal of perlite treatment. Since it is uncertain whether there is a leakage point in the cold box, it will have a certain impact on removal of perlite. No matter whether the leakage is liquid or air, the sand filling holes at the top should be opened first, so that the residual gas in the cold box can be slowly discharged into the atmosphere. The oxygen content of the gas in the cold box and the pressure indication in the cold box should be strictly monitored in removal of perlite process. In the process of sand stripping, it is particularly important to avoid the formation of sand free area in the middle of the cold box, so as to avoid sand storm caused by the sudden drop of pearlite sand.

The lower the upper tower pressure, the more conducive to the separation of oxygen and nitrogen, and for the full low pressure air separation unit, the lower tower pressure will also be lowered as the upper tower pressure is reduced, and the lower tower pressure can reduce energy consumption. The pressure at the top of the upper tower depends on the resistance of the nitrogen piping in the heat exchange equipment and the resis...

capacity The following precautions should be taken in the operation of a pressurised expander: do not allow the interlock to be removed to start the expander under any circumstances. control the inlet temperature of the expander to be no lower than -118°C. It is not permitted to start the expander with the booster bypass valve FCV401 closed, and the expander should be pre-cooled befor...
