Prevention first: Let’s praise and encourage the achievements made in China’s chemical engineering technology and equipment. **********************【Ten Years of Rapid Development in Chemical Engineering Equipment】Regular updates and summaries are available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Engineering Forum) ***************** All hydrogenation units for ethylene and gasoline production in Guangxi Petrochemical’s integrated refining project have been installed. On the afternoon of November 14th, all four gasoline hydrogenation units involved in this project were installed. It took only 7 days from the installation of the first unit on November 9th to the completion of all installations; the total weight of these units is over 2,500 tons. Given the characteristics of the gasoline hydrogenation unit, a modular construction approach can effectively reduce construction costs, minimize operational risks, and improve work efficiency. By using an off-site prefabrication site to carry out the overall prefabrication and installation of the steel structural framework, process pipelines, equipment, electrical lighting, and anti-corrosion/insulation elements for the gasoline hydrogenation modules, the time required for on-site work is reduced. This allows the construction of the gasoline hydrogenation unit modules, as well as the installation of process pipelines and other construction tasks, to proceed simultaneously, thus maximizing the advantages of the construction organization model of \"one site, two work areas\". During this process, since the overall size of the modules after they are assembled is large, transportation becomes difficult due to constraints such as roads and available space. The project team maintained close contact with the transportation companies, inspected the routes for transportation and the installation sites, and accurately calculated the center of gravity and stability angles of the modules to ensure their smooth transportation and successful installation. The 8104# module, installed on the afternoon of the 14th, is 55 meters long, 12 meters wide, 29 meters high, and weighs 999 tons. Thanks to the experience gained from transporting and installing the previous three modules, the installation of the heaviest 8104# module was carried out in a single step – it was installed right after it arrived. Work on assembling the first steel structure component for the gasoline hydrogenation modules began on July 8; after 129 days, the installation of all 4 gasoline hydrogenation modules was completed one day ahead of schedule. During the 100-day intensive phase of the Guangxi Petrochemical integration project, the successful installation of the four gasoline hydrogenation modules served as a boost to the construction efforts of the project team. It also provided valuable experience for the company’s modular construction practices. Going forward, the project team will further complete the subsequent installation work related to process pipelines, electrical and instrumentation systems, as well as anti-corrosion and insulation measures, in order to strive toward the next milestone.
