On February 14, 2022, at the site of Lihua Yi’s 600,000 tons per year propane dehydrogenation PDH project in Lijin County, Dongying City, Shandong Province, as a 2,000-ton crawler crane successfully lifted the final section of the tower, weighing 250 tons, onto the tower structure, the separation tower for this project, undertaken by China State Construction Fifth Engineering Corporation, was completed. With a total weight of 1,830 tons and a height of 128 meters, this separation tower was successfully assembled at a height of 100 meters, marking the successful completion of this project.
China State Construction Fifth Continent participated in the Lihua Yi 600,000 tons per year propane dehydrogenation PDH project, undertaking tasks such as the fabrication and installation of 1 separation tower and 5 propane dehydrogenation reactors. This is another large-scale propane dehydrogenation on-site manufacturing project undertaken by China State Construction Fifth Continent, following the world’s first propane dehydrogenation unit of its kind, with the highest weight and largest production capacity – the Qingdao Jinneng 900,000 tons/year project – as well as the country’s highest-capacity propane dehydrogenation unit – the Yanchang CNPC Taixing Light Hydrocarbons Deep Processing project. Compared with the Qingdao Jinneng and Yanchang Zhongran projects, in Lihua Yi’s 600,000 tons per year propane dehydrogenation PDH project, China State Construction Fifth Continent Group carried out the overhead assembly and lifting of the separation tower on its own for the first time.
The project team from China State Construction Fifth Continent overcame difficulties such as a limited lifting site, transportation challenges, and numerous concurrent operations. By using a 2000-ton crawler crane as the main crane and a 650-ton crawler crane as the auxiliary crane, they managed to position the tower accurately and completed the lifting task successfully. This independent lifting operation marked a first for China State Construction Fifth Continent in terms of lifting work at large-scale propane dehydrogenation projects.
