The lifting of the C-1304 xylene column for Harbin Petrochemical Company’s reformate gasoline xylene separation technology upgrade project was successfully completed. Recently, good news came from China National Petroleum Corporation’s Harbin Petrochemical Branch (hereinafter referred to as “Harbin Petrochemical Company”) regarding this project: the core equipment, the C-1304 xylene column, was lifted accurately and successfully. Taking proactive measures to establish a solid \"first-line defense\" for lifting operations: As the \"heart equipment\" of the project’s core processing units, the C-1304 xylene tower is 76.11 meters in height and has a total lifting weight of 228 tons. Its characteristics of being high, heavy, and delicate, coupled with a complex construction environment, present numerous challenges for the lifting operations. Since the tower is located next to the operating equipment, with numerous process pipelines crisscrossing in the surrounding area and limited construction space, the project team decided to focus on preparations in advance and take comprehensive actions to address the challenges related to the preliminary work. During the equipment prefabrication phase, the project team adopts a \"segmental prefabrication, segmented anti-corrosion treatment, and segmented installation\" approach. By scheduling activities based on the arrival times of various sections of the tower, they carry out prefabrication, application of external anti-corrosion coatings, and installation of insulation layers simultaneously, thereby ensuring the required level of precision in the construction process while also reducing the project timeline efficiently. To meet the subsequent operation and maintenance requirements of the tower, the labor platform is prefabricated and pre-installed in advance, laying the foundation for quick progression of subsequent tasks after lifting. At the same time, to ensure the stable performance of the lifting machinery, all members of the lifting team worked overtime to carry out the disassembly and transportation of components for the 1250T crawler crane, as well as its on-site assembly and testing. Three rounds of load tests were conducted on key components such as the boom and rigging, so as to lay a solid foundation for lifting safety through thorough preparation at every stage of the process. Precise control demonstrates the \"robust strength\" needed to overcome challenges. At the lifting site, machinery is positioned and ready, instructions are conveyed clearly, and personnel in each position are on standby, performing their duties accordingly. This lifting operation employed the \"four-stage sequential lifting method\", with a 1250t crawler crane as the main lifting device and a 280t crawler crane assisting in guiding the load. Due to space constraints, the tower body was delivered in 3 sections, while the equipment base was delivered in 2 sections. The project team first carried out on-site welding, and then proceeded with the lifting, alignment, and fixing operations in strict accordance with the lifting plan. Before lifting each section, safety personnel conduct a dedicated risk briefing, while technical staff verify the dimensions one by one ； During the lifting process, the verticality of the tower is dynamically adjusted through a real-time monitoring system to ensure accurate alignment. The project team leaders were present on site throughout the process, with a command post set up at the site to carry out real-time coordination and control. Quick decisions were made regarding key aspects such as the adjustment of lifting angles and the coordinated operation of multiple cranes, ensuring precise management ； The safety officer leads a team to conduct continuous inspections of the work area, focusing on ensuring the safety of personnel and equipment within the work radius. From the initial lifting to the completion of the final docking, every stage was carried out seamlessly with no operational errors at all, vividly demonstrating the strong capabilities in construction that arise from scientific organization and precise management. Seizing the opportunity to write a \"new chapter\" in development, during these two festive periods, all members of the Harbin project team worked tirelessly on the construction sites with great enthusiasm, using their hard work to offer the strongest blessings for the Republic’s anniversary. Next, the project team will take this milestone achievement as an opportunity to continue working together with various departments of Harbin Petrochemical Company and Xingyou Supervision to effectively address the challenges and obstacles in the project’s progress. Adhering to the principles of \"zero accidents in terms of safety and zero defects in terms of quality,\" the team will accelerate subsequent tasks such as the installation of process pipelines and electrical instruments by using a reverse scheduling approach and systematic planning, striving to get the project up and running as soon as possible and thereby injecting new momentum into the high-quality development of Harbin Petrochemical Company.
