【Ten Years of Great Development in Chemical Equipment】901–2023: The 1.5 million tons per year ethylene plant at Yulong Petrochemical and its 1,960-ton quench oil tower
Thread Content
Ten years of rapid development in chemical processing equipment – praise for China’s prosperity and strength. This is just a starting point; more participation will make things even more lively. HaiChuan becomes even better with you all; we welcome everyone to join in the forum discussions. Happy May Day! Safe and secure Red May ********************************************* The quench oil tower (C-1501) is the largest equipment in the 1# and 2# 1.5 million tons/year ethylene plants of the Yulong Island refining and chemical integration project; its lifting task is heavy and complex. The quench oil tower is transported as a single unit to the lifting site; after the pipeline connections, ladder platforms, and anti-corrosion/insulation measures are installed on the ground, the entire tower is lifted into place. The external dimensions of the equipment are Φ12600*65000*36 mm, with a total lifting weight of 1960 tons. On April 26, the 1,960-ton quench oil tower for Unit 1 of the 1.5 million tons per year ethylene plant in the Yulong Island refining and chemical integration project (Phase I) was successfully installed, marking a critical stage in the heavy equipment lifting work on the Yulong Petrochemical Island. Lifting is carried out using the single-machine lifting and delivery method to position the equipment in place. At the site, the XGC88000 type 4,000-ton crawler crane manufactured by CNPC First Construction Company is used as the main lifting machine, while the XGC12000 (800-ton) crawler crane is employed as an auxiliary crane for lifting. The 4000-ton crawler crane operates in a mode with a dedicated auxiliary arm; it has a lifting counterweight of 1700 tons and a lifting radius of 37 meters. Two cranes worked together to lift the equipment steadily, and eventually it was installed in place successfully.

Due to its large size and weight, as well as the need to turn it almost 90°, the lifting process is difficult, which has drawn significant attention from the supervisor and the owner. During the dressing and helmeting phase prior to lifting, the construction team used three crawler cranes with capacities of 750 tons, 260 tons, and 250 tons (the “trio of cranes”). By employing a balance beam and eccentric method, they successfully lifted and connected an asymmetric U-shaped tube with a diameter of 3.2 meters, a length of 50 meters, and a weight of 86 tons to the quench oil tower, thus setting a precedent for the lifting of the largest-diameter giant pipelines in China to date.
