Happy May Day 2024! Safety first. Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment. **********************【Ten Years of Great Development in Chemical Engineering Equipment】A continuously updated summary post is available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Engineering Forum) ***************** On February 3, 2021, after 7 hours and 17 minutes, the product separation tower for Phase II of Dongguan Juzhengyuan was successfully lifted into place in one go. Lifting is carried out using a 3,600-ton hydraulic lifting system, with a lifting capacity of 2,957 tons. The product separation tower is the core equipment for Juzhengyuan Technology Co., Ltd.’s second-phase project aimed at producing high-performance polypropylene through propane dehydrogenation on a scale of 1.2 million tons per year. The tower is 128 meters tall and has a diameter of 9.2 meters. After the internal components, structural pipes, and insulation materials are installed on the ground level of the tower, along with U-shaped beams and rigging used for lifting, the total weight of this equipment comes to 2,957 tons, making it a true “giant” among tower-type devices. For this lifting operation, a state-of-the-art 3,600-ton hydraulic jacking system was used as the main lifting device. This system is operated via a computer control system, allowing for precise control over the entire lifting process. It features a large lifting capacity, high safety levels, and excellent mobility, which replaces the traditional method of using large crawler cranes to lift such tower structures in stages. This approach significantly improves work efficiency, reduces project costs, lowers operational risks, ensures construction safety, and accelerates the progress of the project. With the lifting command given, the 3,600-ton hydraulic jacking system began to operate noisily; the product separation tower was slowly raised until it was firmly in place on its foundation after 7 hours, marking the successful completion of the lifting operation.
