On April 17, at the construction site of the Guangdong Petrochemical Refining and Chemical Integration Project in Jieyang, Guangdong, a 5,000-ton gantry crane and a 4,000-ton crawler crane were used for the first time to successfully hoist the 4,606-ton raffinate tower into place. In one fell swoop, it broke the record for the heaviest tower hoisting in Asia.
The Guangdong Petrochemical Refining and Chemical Integration Project is the largest refining and chemical integration project invested and constructed by PetroChina to date, including 20 million tons/year refining + 2.6 million tons/ Annual aromatics + 1.2 million tons/year ethylene, of which the 2.6 million tons/year aromatics combined unit is currently the aromatics unit with the largest single production capacity in the world. Once completed and put into operation, it will greatly reduce China’s dependence on foreign imports for aromatics demand and improve raw materials. Self-protection ability.
The raffinate tower hoisted this time is the core equipment of the aromatics complex unit, with a height of 116 meters (equivalent to the height of 41 stories), a diameter of 13.8 meters, and a maximum wall thickness of 145 mm. With a hoisting weight of 4,606 tons (equivalent to the weight of more than 900 adult African elephants), it is the heaviest tower equipment in Asia and the highest tower equipment of its kind. It adopts the integrated construction idea of overall manufacturing, overall transportation, and overall hoisting.
In order to ensure the safety of hoisting the raffinate tower, the First Construction Company of China Petroleum Engineering & Construction Co., Ltd. (CPECC) cooperated with scientific research institutes to conduct finite element analysis and analysis of the hoisting stress. Optimize the plan, determine the equipment placement, lifting lug orientation, and lifting lug diameter parameters, and set up 72 stress detection points where the lifting lug contacts the equipment body to monitor on-site hoisting conditions and accumulate technical data for future large-scale equipment hoisting.
The world’s largest MYQ 5,000-ton gantry crane, developed under the leadership of China Petroleum Engineering Construction Co., Ltd. (CPECC) No. 1 Construction Company, and the “world’s first crane” XCMG XGC88000 4,000-ton For the first time, the crawler crane “combined two swords”. It took 3 hours and 30 minutes to successfully hoist the 4,606-ton raffinate tower into place, setting a new record for the heaviest tower hoisting in Asia and demonstrating the technical strength of China’s equipment manufacturing and hoisting.
Currently, the Guangdong Petrochemical Refining and Chemical Integration Project has completed most of the civil infrastructure construction and entered the stage of full installation. It is planned to be fully completed and put into operation in 2022. The successful hoisting of the raffinate tower laid a solid foundation for the aromatics complex to be put into operation on schedule.
In recent years, Jieyang City is accelerating the construction of “one city, two parks” in Jieyang Binhai New Area. The Guangdong Petrochemical Refining and Chemical Integration Project is located in Jieyang Dananhai International Petrochemical Industrial Zone, covering an area of 953 hectares, with a total investment of 65.4 billion yuan. This project is a strategic project for CNPC to implement the national energy security strategy and realize the transformation and upgrading of its refining and chemical business. It is also a key project to build a new pattern of opening up of Guangdong Province and promote the economic development of eastern Guangdong. </p
