Cold box for air separation equipment

The cold box of the air separation unit is a square or circular metal structure, which is generally the highest mark of the air separation unit. The inside of the cold box includes the main heat exchanger, upper column, lower column, main cooler, argon condenser, liquid argon pump, liquid oxygen circulation pump, liquid oxygen delivery pump and valve pipeline. At the same time, the cold box needs to be filled with pearlite to reduce the cold loss.

No pressure in the cylinder before the air compressor of air separation unit starts

From the starting characteristics of the motor driving the air compressor, it can be seen that the current of the motor starting is several times larger than that of normal operation. The strong starting current has a great influence on the motor itself, transformer and transmission line. In order to reduce the starting time and starting current, no-load is a more effective measure. Based on this requirement of motor starting, before starting the air compressor, the pressure of all levels of pressure gauges should be checked. If there is air, the air should be released.
