As of November 17, the new nitric acid unit of the Ammonium Nitrate Compound Fertilizer Division of the Chemical Sub-Group has been running continuously and stably for 100 days since it was started on August 9, setting a record for the longest operation since the new production unit was put into operation.

Since the start-up of the new nitric acid plant, the leaders of the business department and production technicians have summarized the long-term operation experience of the old nitric acid plant, drawn inferences from each other, strengthened the disposal of leakage and leakage at the production site, clarified the responsibility and the completion period and conducted assessments; optimized the process operation indicators, Adjust the air compressor stator blade opening and steam turbine speed according to different seasons to fully release production capacity; further increase the skill training of operators to improve emergency response capabilities; strengthen process discipline assessment to ensure that operators operate in compliance with regulations and conduct inspections on time. During this period, the major difficulties affecting the long-term operation of the production line, such as the low vacuum degree of the surface cooler, the leakage of nitrogen oxides from the low-pressure fast cooler, and the leakage of nitrogen oxides from the anti-surge valve of the nitrogen compressor, were properly solved, and all kinds of leakage and leakage were dealt with in a timely manner. More than 50, ensuring the safe and stable operation of the device.The stable operation of the new nitric acid plant also ensures the large-scale production of the granular ammonium nitrate plant, which can fully meet the market demand. due strength.
