Deep cooling air separation unit

Causes of low air compressor efficiency of small air separation unit   There are many reasons for the low efficiency of air compressors, the common ones are: increase in suction temperature at any level, cooler leakage, decrease in grid frequency or voltage, blockage or increase in resistance of the compressor intercooler, gas leakage due to poor sealing, blockage or increase in resistance of the air filter, blockage or increase in resistance of the pipeline of the air separation equipmen...

Pressure test of piping in the cold box (1) The system adopts air pressure test, the medium is dry and oil-free air. And must be responsible for the package by a dedicated person partition, strict and careful inspection of the leakage of each part, no leakage is allowed. (2) Before the pressure test, the butt welds of the pipeline should have been checked and qualified, and the valve position holes of all safety valves and automatic valves in the switching process should be blocked with blind ...
