On December 20th, the construction site of the Jiujiang Petrochemical upgrading project was illuminated brightly; the plant area under the night sky appeared as if it were day. The core unit of this project, the light aromatic hydrocarbons separation tower, was successfully lifted into place, and the lights were turned on once the tower was in place. At 9:17, accompanied by the firm commands of the overall lifting supervisor, the lifting operation of the light aromatic hydrocarbon separation tower, a key piece of equipment in the aromatics complex, was officially launched. The light aromatic hydrocarbons separation tower lifted this time is a \"giant\" equipment with a length of 100 meters and a weight of 920 tons; with the combined effort of a 4,500-ton main crane and a 1,000-ton auxiliary crane, it was slowly raised off the ground and lifted into the air smoothly. “The moment the lights came on marked a crucial step forward toward achieving operational readiness. ”The project leader stated that this lifting task involves a tight schedule, high difficulties, and significant risks, and represents a critical milestone in the construction of the aromatic compounds complex. To ensure everything goes smoothly, the various departments of the project team planned ahead and worked together as a team. They set the lifting deadline for December 20th and worked backwards to determine the schedule, paying close attention to every detail: from the transportation of large items and preparation of the foundation for lifting, to the formulation and approval of lifting plans, the procurement of materials needed for the construction, and the actual construction process itself; from organizing the on-site work to implementing safety measures, excellence was pursued in each step, with strict control over all aspects. With the close cooperation of all parties on site, the lifting operation was carried out safely and under control throughout, with all parameters meeting the expected values accurately. After 2 hours of steady operation, the light aromatic hydrocarbons separation tower was successfully installed in one precise attempt, marking a significant milestone in the construction of the aromatic hydrocarbons complex. This achievement accelerates the subsequent tasks of equipment installation, pipeline connection, and commissioning of the plant.
