On December 12, 2023, the flagship equipment of Sinopec’s shipping company – the XGC88000 model 4,000-ton crawler crane – successfully completed its first lifting task as part of CNPC’s Jilin Petrochemical transformation project. It continued to set new records for lifting capacity, establishing a new standard for safe operation in extremely cold conditions. The ethylene tower being lifted this time is one of the five oversized towers that are crucial for the transformation and upgrading of Jilin Petrochemical’s 1.2 million tons per year ethylene production facility. The tower has a diameter of 6.6 meters and a height of 90.6 meters, with a total lifting weight for the equipment of 1160.5 tons. The lifting operation was carried out using the single-machine lifting method; a 4,000-ton crawler crane was employed as the main lifting machine at the site, with an XGC17000 1,250-ton crawler crane used to assist in completing the lifting process.
On the morning of January 18, 2024, the No. 2 propylene column of the 1.2 million tons per year ethylene plant, part of Jilin Petrochemical’s project for upgrading its refining and chemical operations, was successfully lifted into place. With this, all the large-scale, oversized tower structures of this plant have been installed, and work has now fully shifted to the stages of equipment installation and process piping.
The newly built 1.2 million tons per year ethylene plant at Jilin Petrochemical features 17 tower vessels that exceed standard dimensions; among them, 5 large-scale tower vessels require the use of a 4,000-ton main crane and a 1,250-ton auxiliary crane for lifting. The No. 2 propylene tower lifted this time is the last of the 5 large-scale, oversized towers; it is also the tallest tower in this facility and the most difficult to lift, making it a veritable \"king of towers\". The tower was constructed using a method of segmented manufacturing, segmented transportation, and overall lifting. With a length of 111.25 meters and a total lifting weight of 2,030.8 tons, it is one of the vertical reactors in China that boasts the greatest lifting weight, largest volume, and highest height among such devices.
