In 2026, the 25th National \"Safety Production Month\" will see everyone emphasizing safety and being capable of handling emergencies, as well as efforts to identify and address potential risks and hazards. At 12:30 on June 24th, the first water-cooled reactor for the methanol synthesis unit in Phase 1 of the olefins, aromatics, and advanced processing project under Shaanxi Coal Group Yulin Chemical Co., Ltd.’s 15 million tons per year coal conversion demonstration project was successfully installed, marking the beginning of the installation work for the facility’s equipment and paving the way for an accelerated project timeline. The methanol synthesis unit of Phase 1 of Yulin Chemical Phase II is the largest single-series methanol plant under construction in the world, with a designed annual production capacity of 2×2.8 million tons. The water-cooled reactor lifted this time is the core equipment of the entire system. It features Lurgi’s patented shell-and-tube design, which allows for the catalytic synthesis of methanol while simultaneously recovering waste heat to generate steam, thereby achieving both efficient production and energy savings. After high-temperature forging, meticulous processing through hundreds of steps, and multiple rounds of rigorous testing, the equipment was successfully delivered to the construction site on June 23. To ensure the safe and efficient progress of the lifting operations, the Methanol Project Department carried out specialized planning in advance, refined the construction plans, precisely allocated human resources, equipment, and materials, and scientifically optimized the timing of the delivery of large-scale components as well as the procedures for their on-site installation. Throughout the entire operation, strict accountability for safety management was enforced, and construction standards were adhered to, enabling the lifting task to be completed smoothly and accurately. It is reported that the water-cooled reactor lifted this time has a diameter of 4.98 meters, a height of 16.6 meters, and a total weight of 562 tons. The project team adopted a dual-crane lifting scheme consisting of a 1250-ton crawler crane as the main crane and a 400-ton crawler crane for assisting with the lifting process. The main crane was a QUY1250 model with a capacity of 1250 tons; it was operated in its jib-lifting mode, with a jib length of 72 meters and an operational load factor of 87.2%. The installation of the first core equipment this time has provided practical experience for the subsequent installation of larger components, and it has also laid a solid foundation for the timely completion and commissioning of the second-phase project, thereby enabling the expansion of production capacity.
