Installation of key large-scale equipment exceeding 1,000 tons for the 300,000 tons/year PEO production facility in Rongsheng New Materials project completed
Thread Content
On January 6, 2026, a significant milestone was reached at the Rongsheng New Materials project’s 300,000 tons per year PEO production facility: all four key large-scale equipment units within the 10A reaction framework were safely and precisely installed, marking the official conclusion of the equipment installation phase of the project. The four pieces of equipment lifted in this batch are core components of the plant’s process flow, and their successful lifting marks a milestone for the entire project. The reactor/gas cooler (1225-R-0110) has a net weight of 1,063 tons, making it the heaviest single piece of equipment in the facility at present; its installation elevation is 20.85 meters. Reactor gas cooler drum (1225-V-0110), weighing 232 tons. The reactor gas cooler drum (1225-V-0112) weighs 120 tons and has an installation height of 18.15 meters. Gas-to-gas heat exchanger (1225-E-0111), weighing 216 tons. Among them, the lifting of the reactor gas cooler drum (1225-V-0112) was the most technically challenging and complex aspect to coordinate in this operation. The device must be precisely placed on a specific base inside the frame; the space is limited and the paths are circuitous. Through precise calculations and simulations, the project team developed an innovative solution of \"lifting with two machines and pulling within the frame\": first, a 1600-ton crawler crane is used to lift it to the specified height at the edge of the frame. Subsequently, with the coordinated effort of 280-ton crawler cranes, a relay delivery process was carried out to smoothly transfer the equipment onto the specially prepared fixtures. Finally, the construction workers used multiple sets of large winches for precise pulling and adjustment; akin to threading a needle, they slowly moved this 120-ton \"giant\" onto the equipment foundation at a height of 18.15 meters, achieving placement with millimeter-level accuracy. The entire process is a model example of precise indoor installation of large-scale equipment.
The lifting of the much-talked-about \"giant\" – the 1,063-ton reactor/gas cooler (1225-R-0110) – represented a comprehensive test of the project team’s organizational skills, technical expertise, and ability to handle emergencies. The equipment must be precisely aligned at a height of 20.85 meters; any minor deviation can lead to serious consequences. The project adopts the classic lifting method of \"a 1,600-ton crawler crane for main lifting and an 800-ton crawler crane for assisting lifting\". Introduction to the Jintang New Materials Project
