Recently, the PC&BPA combined plant of the Fujian Zhongsha Gulei project, which is under the general contract of China National Chemical Corporation Tianchen, reached an important milestone. The core equipment of the isopropylbenzene plant, the isopropylbenzene tower, was successfully lifted in one go after being equipped with its necessary components, marking the successful completion of the lifting ceremony for the first tower. The project has now entered the intensive phase of equipment installation, laying a solid foundation for the smooth progress of the entire project timeline. The isopropylbenzene tower lifted this time is one of the core equipment in the plant. The project team adopted the \"single-machine lifting and delivery method\", using a hydraulic synchronization lifting system to precisely control the displacement. To ensure the precise installation of the equipment, the project team adhered to the philosophy of \"planning first, technology as a safeguard,\" carrying out multiple rounds of scheme evaluation and technical research. By accurately calculating the crane’s operating radius and load distribution, as well as by developing detailed plans for equipment transportation and path optimization during lifting, complex challenges such as limited construction space and high vertical lifting heights were effectively overcome. Ultimately, with the triple guarantees of safety, quality, and efficiency, this milestone was successfully achieved. Taking this lifting operation as a model, the project team will continue to advance the group company’s \"135\" strategic plan, systematically promoting the development of a grid-based management system at the project site, as well as the professionalization of technologies, the standardization of practices on site, and the standardization of behaviors. By making simultaneous efforts in quality control, safety management, and progress optimization, we ensure the project progresses efficiently and to a high standard, striving to create a construction site that meets five-star standards. This will set a new benchmark for China-Saudi cooperation and contribute Tianchen’s strength to the new phase of high-quality development for the group company!
