At 18:18 on August 22, the primary lifting of the C13 tower, the core equipment for the C13 liquid wax separation process in Jinxī Petrochemical Company’s urea dewaxing unit, was successfully completed. The successful completion of this key milestone marks a significant breakthrough in the construction of this project, laying a solid foundation for the full rollout of subsequent work. As the core equipment for the urea C13 liquid wax separation project, the lifting of the C13 removal tower is considered the highlight of the entire project. This device is not only the largest and heaviest core component in the project, but its installation accuracy also directly affects the operational efficiency of the entire system. Data shows that the overall height of this equipment is 42 meters, with the maximum lifting height reaching 59.7 meters; its net weight is 31.1 tons, and its total weight after prefabrication is 52 tons. To ensure a flawless lifting process, the construction team used an 800-ton truck crane as the main lifting device and a 300-ton truck crane for assistance, enabling precise control through the coordinated use of both cranes; as a result, the installation was completed with zero deviation. The successful lifting was made possible by the project team’s thorough preliminary preparations and innovative construction methods. The Project Management Department of Jinxi Petrochemical led multiple departments in conducting thorough evaluations and rigorous reviews of the lifting plan, ensuring precision in every detail – from the analysis of stress on the equipment to the selection of lifting points, from the assessment of weather conditions to the preparation of emergency response plans. It is worth noting that the project team innovatively adopted a \"prefabrication on the ground followed by overall lifting\" approach, in which the process pipelines attached to the tower, the anti-corrosion and insulation layers, as well as the safety equipment were all prefabricated on the ground. Only after passing non-destructive testing and visual inspections were they lifted into place as a whole. This measure not only significantly reduces the risks associated with working at heights, ensuring both safety and quality in construction, but also effectively shortens the project timeline, creating favorable conditions for accelerating project progress. The successful installation of the C13 removal tower marks the official transition of the urea C13 separation project to new phases such as the installation of process pipelines and electrical instrumentation. The head of the Engineering Management Department said that the project team will continue to uphold the \"Strive for the best, aim for excellence\" spirit associated with the \"First Oil Train\" initiative. Taking this successful lifting operation as an opportunity, they will make every effort to accelerate the construction progress and ensure that the facility is completed and put into operation as soon as possible. It is understood that the completion of the urea C13 liquid wax separation project will further optimize the product structure of Jinxi Petrochemical, improve the efficiency of liquid wax separation as well as the added value of the products, thereby injecting new momentum into the high-quality development of the enterprise.
