On the 11th, reporters learned from Sinopec Henan Refining & Chemical Company that the product fractionation tower, the largest single unit of the hydrocracking unit as part of the refining facilities for the company’s million-ton ethylene project, was successfully installed recently. This marks a new phase in accelerating the construction of this project, providing strong impetus for Luoyang to develop a high-quality industrial chain for chemical new materials. 　　In the refinery supporting projects for the million-ton ethylene project, the hydrocracking unit plays a crucial role in improving the quality of petroleum products and providing raw materials for the chemical industry. The product fractionation tower is the “core hub” of this facility, and its successful installation marks a milestone in the advancement of the entire project. 　　The product fractionation tower that was lifted this time has an outer diameter of 5.4 meters and a height of 63 meters; it is equipped with 70 layers of tray supports, and the total weight of the metal structure is over 220 tons. Since arriving at the construction site on January 23, the construction team efficiently completed the installation of various accessories such as pipelines, platforms, ladders, and railings, as well as the anti-corrosion and insulation work. As a result, it was possible to lift the structure weighing 350 tons. The high difficulty of this lifting operation and the stringent technical requirements make it one of the most challenging tasks in similar projects. To ensure the success of the lifting operation, the construction team planned ahead and made systematic arrangements, developing a detailed lifting plan. A 1600-ton crawler crane was used as the main lifting device, with a 400-ton crawler crane serving as an auxiliary. A professional command and operation team was assembled, and various simulation drills were conducted to thoroughly identify any potential safety hazards. 　　At 7:17 on the 10th, the lifting command was officially issued. The 1,600-ton crawler crane gradually applied force, with the 400-ton crane coordinating seamlessly; the product distillation tower, which was initially lying flat, was slowly raised. Once the tower was vertical relative to the ground, the 400-ton crane smoothly removed its hook and withdrew. Subsequently, the 1600-ton crane precisely adjusted the angle of its boom to slowly lift the fractionation tower to the specified height. Through smooth displacement and precise alignment, the bottom of the tower shaft successfully passed through the pre-arranged hole, with the skirt base settling in place firmly. The construction workers promptly carried out the calibration tasks, tightening each of the 48 bolts one by one; at the same time, the lights came on once the tower was erected. The entire process was conducted safely, efficiently, and accurately, allowing the lifting task to be completed successfully.
