On June 18, the main motor of the air compressor of the newly-built air separation unit was equipped with single-machine trial operation conditions. Relevant personnel such as maintenance, electrical, instrumentation workshops, and manufacturers conducted pre-commissioning inspections to make final preparations for the smooth operation of the air separation unit.

   After the new air separation unit is completed and put into operation, it can reduce the cost, effectively avoid the risks brought by the liquid nitrogen extracted, provide a reliable guarantee for the nitrogen demand of each unit after overhaul, and further improve the stability of the unit operation.
