On January 9, the South China branch of Sinopec Fourth Construction Company reported that good news has come from the construction site of the No. 2 aromatic compounds unit at Zhongke (Guangdong) Refining and Chemical Plant, which is being built by this company. Since intensive lifting operations began in late December 2025, the project team has successfully completed the installation of all the large-scale towers, finishing six days ahead of schedule and thus laying a solid foundation for subsequent construction work. This lifting task involves multiple large-scale critical equipment. On December 20, 2025, the large-scale tower equipment, with a maximum diameter of nearly 9 meters and a weight of 15 tons, was successfully installed first, marking a good start. Subsequently, the project team seized the opportunity and, on December 24, 2022, successfully lifted and installed the first heavy-duty 100-ton tower unit – a large tower device with a diameter of over 5 meters and a weight of 125 tons, which was placed in position smoothly ； Two days later, the large tower unit with a maximum diameter of over 5 meters and a weight of 125 tons was also successfully installed in its place. This marks the completion of the installation of all three key towers that the company planned to install by December 2025, representing a significant milestone. As the new year 2026 begins, the company’s lifting operations are once again at a peak. On January 5, the largest and heaviest core equipment in the facility was safely and precisely installed: the large extraction distillation tower, with a maximum diameter of over 7 meters and a weight of 240 tons. From January 8th to 9th, the company’s project team worked at a rapid pace of \"three lifts in two days,\" successfully lifting heavy units weighing over 100 tons each, including the solvent recovery tower, the non-aromatic hydrocarbons distillation tower, and the pentane removal tower. As a result, all tasks related to the lifting of these large-scale towers were completed ahead of schedule. During the lifting operations, the company’s project team effectively reduced the interval between lifts by optimizing the arrival sequence of multiple pieces of equipment ； For super-tall towers, the pre-hanging position is accurately calculated in advance to ensure the efficient completion of preliminary assembly tasks such as fitting components in place ； The single-machine lifting and delivery method was used throughout the process, providing the main crane with the optimal working space and ensuring that all towers were lifted successfully in a single attempt. The successful completion of this lifting task has provided valuable experience for similar engineering projects, and it has also injected strong momentum into the further advancement of the company’s engineering projects.
