News on November 20: Recently, news came in from the site of the Yangmei Taohua caprolactam project – the reboiler for the butanol low-pressure tower, a key piece of equipment for the project, was successfully lifted into place. This achievement at this crucial stage not only lays a solid foundation for the project to meet its annual goals but also contributes to Shanxi’s development of a modern chemical industry cluster through the efforts of a central state-owned enterprise. The reboiler of the butanol low-pressure column, a key piece of equipment for Yangmei Taohua’s caprolactam project, has been lifted into place. The butanol low-pressure column reboiler, which was successfully lifted this time, can be regarded as the \"heart\" equipment of the project’s production system. With a net weight of 75.5 tons, a diameter of 3 meters, and a height of 20.6 meters, it not only serves as the core component of the entire caprolactam project but is also the equipment with the greatest individual weight in this project. Faced with various challenges such as the large size of the equipment, strict requirements for lifting precision, and limited working space on site, the project team made full use of the technical and managerial strengths of central state-owned enterprises to carry out all preparatory tasks with great care and precision. The team established a dedicated task force in advance, bringing together departments such as construction, technology, and safety to create a coordinated working framework. They repeatedly simulated the lifting process and optimized the selection of machinery, conducting precise calculations for every turn along the lifting route and for the stress levels at each crane position, to ensure everything ran smoothly. On the day of the lifting operation, the command signals at the site were clear, and everyone involved performed their duties accordingly. The 500-ton main crane lifted steadily, while the 200-ton auxiliary crane provided precise support to guide the equipment. The massive machinery was raised slowly and rotated smoothly under the blue sky and white clouds, with the entire process being carried out with great precision, as if threading a needle. After nearly two hours of continuous effort, the equipment was successfully installed in place. The on-site technicians immediately used professional instruments for testing, and the results showed that key parameters such as the verticality and levelness of the equipment installation met all the design standards, ensuring a successful installation on the first attempt with accurate results from the start. The successful completion of the lifting of these key equipment units marks the official entry of the Yangmei Taohua caprolactam project into its peak equipment installation phase, removing obstacles to the efficient progress of subsequent tasks such as pipeline installation, instrument installation, and anti-corrosion and insulation work. This achievement not only demonstrates the excellent skills and high standard of China National Chemical Second Construction Corporation in the installation of large-scale chemical equipment, but also highlights the pivotal role played by central state-owned enterprises based in Shanxi in supporting the region’s industrial transformation.
