Multiple images! ! The super-large equipment for the Huajin AAME fine chemicals and raw materials project has been gradually delivered to the site

On October 28, 2024, the first batch of products from the fine chemicals and raw materials production project at Northern Huajin United Petrochemical, manufactured by Zhanghua Machinery, was successfully delivered. Among them, the quench oil tower in the 1.65 million tons/year ethylene plant has a diameter of 13 meters, a length of 53 meters, and a total weight of 1,103 tons; the quench water tower has a diameter of 12.1 meters, a length of 62.3 meters, and a total weight of 1,273 tons ； The methanol scrubber Tower I in the low-temperature methanol washing purification unit, with a diameter of 4.3 meters, a length of 103.8 meters, and a total weight of 1,253 tons, as well as the H2S concentration tower, were all delivered successfully. Of the four units delivered this time, three are ultra-large towers in the thousand-ton class. At the initial stage of the Methanol Wash Tower I project, to ensure smooth progress of on-site construction, the Zhanghua Machinery project team and the production management team made reasonable arrangements and thorough plans. During the product manufacturing phase, all team members, driven by a spirit of unity and determination, successfully overcame a series of technical challenges, including variable weather conditions, tight manufacturing schedules, as well as issues related to controlling the ellipticity of towers with extremely large diameters and welding full-penetration joints in thick-walled low-temperature steel. It is possible to effectively keep the ellipticity of thin-walled towers with a maximum diameter of 13 meters within 20 millimeters, and full-position welds made from low-temperature steel with a plate thickness of 100 millimeters can pass inspection in a single test. These practical actions not only ensured the smooth progress of production but also guaranteed that the delivery deadlines specified in the contract were met.
