On July 23, the main motor of the air compressor of the newly-built air separation unit was equipped with online test operation conditions. All relevant professionals went to the site to conduct a final pre-commissioning inspection of the air separation unit to make a final inspection of the air separation unit.

   The liquid nitrogen used in previous installations had to be purchased externally, which was costly and caused certain risks to the safe and stable operation of the installations.

   After the air separation unit is put into use, it provides a reliable guarantee for the nitrogen demand of each unit, and further improves the stability of the unit operation.
