On June 23, the air separation unit of the Tarim 1.2 million tons per year Phase II ethylene project, which is being constructed by the Kunlun Engineering Project Group, reached a significant milestone: the first key equipment in this unit, the 141-V-1002 high-pressure nitrogen storage tank, was successfully lifted into place, marking the official entry of the project into a new phase of actual equipment installation work. With limited time and a heavy workload, scientific planning is essential to meet the challenges. This lifting task was quite demanding: the 141-V-1002 high-pressure nitrogen storage tank is located on the east side of axes C9-C10 in pipeline gallery #C of the main plant. The weight of this equipment is 65.17 tons. A 300-ton truck crane and a 130-ton truck crane were used for lifting it respectively. The installation height is 15.2 meters, which presents high safety risks; it is one of the heaviest single units of its kind in this plant at present. The equipment is large in size, placing extremely high demands on lifting techniques, construction organization, and safety management. Faced with challenges such as tight deadlines, limited construction sites, and high difficulties in the work, the project team planned ahead, made scientific arrangements, and optimized the construction organization to ensure that the lifting operations proceeded safely and efficiently. With a well-organized structure, efficient emergency response capabilities, and full commitment to meeting deadlines, the project team made thorough preparations in advance to ensure the successful lifting of large-scale equipment. A detailed lifting plan was developed, with a 300-ton truck crane used as the main lifting device, supported by a 130-ton truck crane for coordinated operations. Every detail was carefully analyzed and optimized (lifting radius, range of motion, maximum lifting height). At the same time, construction schedules are adjusted flexibly, large amounts of human, material, and equipment resources are allocated to focus efforts on overcoming challenges, with priority given to meeting lifting requirements. Under the careful organization and precise coordination of the project team, the lifting operations were carried out safely and efficiently, successfully laying a solid foundation for subsequent construction work. Widely recognized as a testament to the strength of the \"Kunlun Project\", the project department and various parties involved in PMT4 have given it high praise, highlighting that the Kunlun Project, thanks to its excellent management skills, meticulous planning, and sophisticated construction techniques, overcame numerous difficulties to successfully complete this crucial construction phase. The efficient and high-quality results achieved in the Kunlun Project fully demonstrate its outstanding execution capability and sense of responsibility. Moving forward with determination and striving hard to achieve further success, the air separation plant project is now entering its peak installation phase. The project team will continue to uphold the spirit of overcoming challenges and working hard, bringing greater enthusiasm and more diligent effort to advance to the next construction stage, ensuring that the project is completed on time, to high quality, and successfully.
