The 73-meter-high core tower of Fuhai Chuang’s 500,000 tons/year heavy aromatic hydrocarbons lightweighting project was erected and its lights were turned on

Recently, the core tower of the 500,000 tons per year heavy aromatic hydrocarbons lightweighting project undertaken by Fujian Provincial Industrial Equipment Installation Co., Ltd. was successfully lifted into place. As the \"heart of equipment\" for the 500,000 tons/year heavy aromatic hydrocarbons lightweighting project, the 73-meter-tall core tower was successfully brought online, setting a new record for height in the Fuhai renovation and expansion project. It is reported that this project was constructed by Xiamen Branch of Fujian Installation. The core tower weighs 151 tons; the total lifting weight is nearly 200 tons, and its height is 73 meters, which is equivalent to the height of a 20-story building. Due to its great height, complex structure, limited space at the project site, and frequent concurrent operations, the traditional on-site assembly method faces significant challenges. To overcome this challenge, the project team conducted multiple rounds of technical evaluations and scheme optimizations, opting for an 800-ton large crawler crane as the main lifting device and a 400-ton crawler crane as a supplementary one, so that the two cranes could work together to apply precise lifting forces. At the same time, the team innovatively adopted an external dressing and covering construction method, carrying out all processes such as anti-corrosion and insulation treatment of the towers as well as the assembly of accessories outside the factory. This ensured that the equipment left the factory in its \"fully prepared\" state. By breaking away from conventional transportation approaches and using a method of transporting the equipment in its fully dressed and covered form, not only were the risks associated with concurrent operations due to limited on-site space avoided, but the on-site construction period was also significantly reduced, thereby improving both the accuracy of installation and the safety of the construction process.
