On December 15, the sulfuric acid thermal station, a key component of the \"heat source\" system at Jilin Petrochemical Company’s acrylonitrile plant, successfully passed the trial operation assessment with all parameters within normal ranges. Once in operation, this thermal plant will be able to completely replace the three existing heat exchange stations, taking over the entire plant’s heating functions and providing a stable heat source for various chemical processing units as well as heating users. It is expected to save 1,630 tons of steam per month, resulting in cost savings of 282,000 yuan per month. The sulfuric acid thermal power plant is an important component of the western region’s transformation and upgrading project, and construction began in May 2024. During this period, the heat pump unit underwent 3 trial runs and adjustments, resolving 5 issues including seal leakage in the P-23001A/S hot water circulation pumps, leakage in the condenser head, and low voltage in the unit’s cooling solenoid valves. It was finally put into operation at 10:46 on November 26. The core equipment of this thermal station is a technologically advanced imported heat pump unit. The unit is equipped with one heat pump unit, three hot water circulation pumps, and two variable-frequency make-up water pumps. The heating capacity of a single heat pump is 10 MW, allowing it to completely replace the three heat exchange stations in the Tripropylene Workshop, Propylene Workshop, and Finished Products Workshop, thereby providing a stable heat source for the plant’s water heating system and heating system.
