after 12 hours of intense work, at 6:34 p.m. on september 20, the core equipment of jilin petrochemical's second acrylonitrile unit, the 97.6-ton reaction gas cooler, was successfully replaced.
acrylonitrile is one of the main products of jilin petrochemical. the second acrylonitrile unit can produce 106,000 tons of acrylonitrile per year, accounting for 1/4 of the company's acrylonitrile production capacity. as the "heart" of the acrylonitrile unit, the reaction gas cooler plays a key role in cooling the reaction gas, which directly affects the quality and production capacity of acrylonitrile products.
the reaction gas cooler is oversized and overweight, and the replacement process involves hoisting, climbing, temporary power operation, hot work, etc., which is highly dangerous and difficult to construct. at the beginning of the year, jilin petrochemical acrylonitrile plant listed the replacement project of this equipment as a key project for this year's major overhaul, and organized various professional departments to conduct multiple rounds of on-site discussions and repeatedly demonstrated the feasibility of the construction plan.
in mid-september, the 600-ton crawler crane entered the on-site assembly. the local workshop supervisors supervised and monitored around the clock, carefully checking every small step of the equipment assembly and strictly controlling the installation quality, laying a solid foundation for the next step of replacement operations.
at 6:20 am on september 20, as the order to replace the reaction gas cooler was issued, professional departments, local workshops, and construction units quickly entered the site, and all personnel carried out construction work in an orderly manner according to the established plan, from removing the old cooler to completing the lifting of the new cooler. after 12 hours of collaborative efforts, the entire "heart replacement" process went smoothly.
