On June 1, after 13 hours of continuous work, the large-scale equipment – specifically Tower 2 for xylene production – of Sinopec Jiujiang Petrochemical’s aromatics project was successfully lifted into place, marking the completion of this installation process. With this, the lifting of all four ultra-large key pieces of equipment in the aromatics complex has been finished, signaling yet another major milestone achieved in the progress of this project. The No. 2 xylene tower C-8021, which was lifted this time, is the last super-large core equipment in the aromatic main plant, following the raffinate tower, No. 1 xylene tower, and adsorption tower; it is also the tallest large-scale tower in the entire project. The tower is 98.8 meters tall and 6.4 meters in diameter, with a lifting weight of 1430 tons. The lifting process involves using a 2600-ton hydraulic lift as the main lifting device, along with a 1250-ton crawler crane to assist in lifting it. With the 52 foundation bolts successfully inserted into the holes in the tower skirt foundation, this lifting task was completed successfully. The tower was delivered to the project site in three sections on January 19, 2021. After 4 months of assembly and welding, as well as the installation of various components, it passed the on-site assembly inspection on May 29 and began its hovering operations; the final checks prior to lifting were completed on May 31. To ensure the smooth execution of this lifting operation, the Aromatic Compounds Project Department drew on the experience gained from previous lifting tasks, maintained active communication with the construction party, assembled a capable team to work closely together. By overcoming challenges such as frequent rain, limited space, tight deadlines, and high risks, the team strived to optimize the construction plan, worked overtime to improve efficiency, and organized supervisors, third-party safety inspectors, and the construction party to carry out safety briefings prior to the lifting process. Safety barriers were set up in the work area, and strict safety monitoring was implemented to ensure the successful completion of the lifting task. Source: Refining and Petrochemical News
