Precise lifting of the butylene refining tower, the first key process equipment for the POE unit in the Blue Sea New Materials project

Thread Content

On January 10, at the construction site of the Blue Sea New Materials project undertaken by the company, a large crawler crane lifted the butylene refining tower – the first key process equipment for the POE facility – smoothly and precisely to its designated location. This marks the full commencement of the equipment installation work for this project, pushing the overall construction into a critical phase. On January 12, the dehexane tower was successfully lifted. The tower is 28.085 meters tall and weighs 21,625 kg; lifting was carried out using 400-ton and 320-ton crawler cranes in coordination. The butene refining tower that was installed earlier was 29.27 meters tall and weighed 19,730 kg; it is one of the key towers in the POE production facility, used primarily for the purification and separation of the butene component in the raw materials. The accuracy and quality of its installation have a direct impact on the stability of subsequent processing operations as well as the quality of the product. This lifting operation was carried out after thorough preparation and technical briefings; it progressed smoothly throughout, with the tower being placed in position successfully in one attempt, and the accuracy met all design requirements. As a key component of the strategic plan for the industrial development of high-end polyolefin elastomers (POE) in China, the Blue Ocean New Materials project holds great significance for enhancing the country’s capacity to develop new chemical materials independently. The precise installation of the butylene refining tower this time is not only an important milestone in the project construction but also highlights Liumian Company’s leading technical expertise and outstanding project management capabilities in the installation of large-scale chemical plants. The successful installation of the first core tower has not only provided systematic experience for the subsequent construction of mechanical and electrical equipment, but also laid a solid foundation for fully achieving the project’s mid-term goals.
