On December 28, the xylene tower, a key equipment in the aromatics complex of Jiujiang Petrochemical’s 1.5 million tons per year aromatics project, was installed two days ahead of schedule. This lifting operation represents another positive development in the project’s construction, following the successful installation of the Qingfang separation tower on December 20. The xylene tower, a key piece of equipment in the aromatic compounds complex, operated smoothly for 3 hours, enabling a successful and precise lifting operation on the first attempt. It is reported that the xylene tower, which is the tallest, largest in diameter, and heaviest among the tower equipment in the aromatic compounds complex, has set new records for all the equipment in Complex No. 2 with its impressive specifications of 111 meters in height, 1,200 tons in weight, and 8 meters in diameter – making it the \"best\" among the equipment in this complex. The project team carefully planned the construction approach, innovatively adopting a work model of \"factory prefabrication, modular installation, and multi-disciplinary collaboration.\" Faced with the technical challenges associated with lifting such large-scale equipment, the project team conducted multiple rounds of scenario analysis before finally deciding on a lifting plan that involved using a 4500-ton crane for the main lifting operation and a 1000-ton crane to assist in stabilizing the load. Special safety measures were also developed, with detailed plans put in place for key aspects such as reinforcing the lifting points, ensuring balance during the lifting process, and establishing safety barriers at the site, all to guarantee success. It is understood that this lifting task faces triple pressures of a tight schedule, heavy workload, and high standards. Since the project was launched, the project team has focused on the lifting deadline of December 28th, working backwards from this date and using visual planning to coordinate all aspects of the work (equipment manufacturing, transportation for lifting, assembly and welding, hydraulic testing, and final finishing). All departments work closely together: from the multi-level approval process for lifting plans and the assurance of material procurement, to on-site construction organization and the allocation of tasks among personnel, every aspect is carefully planned and strictly monitored, ensuring a flawlessly prepared environment that lays the foundation for the smooth execution of the lifting operation.
