On February 31, at the end of the old year as a new one was about to begin, with the last fixing rigging properly installed, the upper section of the pre-distillation column – the core equipment for the butylene production project at Inner Mongolia Baofeng Coal-based New Materials Co., Ltd. – was successfully lifted into place. The successful completion of this critical milestone not only marks the perfect finish of the heavy-lifting operations for this project, but also lays a solid foundation for the subsequent installation and commissioning work. The equipment for the upper section of the lower column of the pre-distillation tower to be lifted this time is large in size: it has a diameter of 6.6 meters, a height of 31.4 meters, and a weight of 240 tons. The area available for lifting operations is limited, which restricts the space for carrying out these tasks. Moreover, it is located adjacent to an already operational unit, so any carelessness in the operations could pose safety risks. To ensure the success of the operation, the project department, in collaboration with the equipment manufacturer and the lifting company, formed a dedicated task force. Multiple technical briefing meetings were held to continuously optimize the lifting plan. From the survey of transportation routes and site grading, to the selection of lifting equipment and the verification of rigging strength, as well as the development of emergency response plans, every aspect was carefully calculated and meticulously planned, thereby establishing a solid safety framework to ensure the successful completion of the lifting task. On the day of the lifting operation, at the command given by the project’s lifting supervisor, the 1250-ton crawler crane and the 450-ton crawler crane worked together. Thanks to their extensive experience and skilled techniques, the operators were able to precisely control the cranes’ lifting, rotating, and positioning actions ； The on-site lifting personnel worked closely together, monitoring the equipment’s posture and stress levels in real time, and adjusting the operational parameters as needed. Thanks to the seamless coordination between the two vehicles, the equipment was gradually moved from a horizontal position to a vertical one. Once the equipment was stable, the 450-ton crawler crane released the hook. The entire process was safe, efficient, and orderly, with all technical parameters meeting the expected standards, thus bringing the project construction for 2025 to a successful conclusion. The new C4 project in Baofeng, Inner Mongolia, represents another market expansion by Shaanxi Chemical Construction following its olefin projects. The main production units include selective hydrogenation, super pre-distillation, 2-butene isomerization, etherification for isobutylene removal, and precision distillation. The utility and auxiliary systems are based on the existing coal-to-olefins facility at the site; once operational, the project will generate approximately 250,000 tons of mixed C4 products per year as a by-product. This large-scale lifting operation was successfully completed on the final day of 2025, marking the full achievement of the project’s construction goals for that year. Next, all personnel involved in the project will accelerate the construction of equipment, process pipelines, and electrical instruments, paying close attention to quality, safety, and schedule considerations. They will make every effort to meet the project completion deadline, thereby injecting new momentum into the regional economic development and contributing to the high-quality growth of Shaanxi Chemical Construction.
