Total investment of 9.68 billion yuan! Lifting of core reactors for acrylic acid unit in Yueneng’s 1 million tons/year high-end chemicals and new materials project 2025-05-06 From May 4th to 5th, the 1 million tons/year high-end chemicals and new materials project undertaken by Yueneng Fine Chemicals Company reached a key milestone: the first and second reactors, which are the core equipment of the acrylic acid unit, were successfully lifted and rotated despite the challenges involved. For this lifting operation, a \"double main cranes + auxiliary crane for tail pulling\" approach was adopted, with two 500-ton class truck cranes serving as the main lifting devices and one 300-ton class truck crane acting as an auxiliary crane for pulling the load. Strict adherence to safety procedures was maintained throughout the process to ensure that the lifting operations were carried out smoothly and in an orderly manner. As the core equipment in acrylic acid production facilities, the two reactors installed this time have notable features: the first reactor weighs 260 tons in total, with dimensions of φ6550×4700mm ； The second reactor weighs 200 tons, with dimensions of φ6650×3440 mm. During the operation, the staff successfully carried out a high-precision rotation of the equipment from an upright position to a horizontal position, thereby creating ideal conditions for the subsequent challenging pipe-end welding and precision expansion processes. It is understood that since the on-site manufacturing of these two core Jiacai equipment units began on December 10, 2024, the company, in collaboration with Xi’an Huawei Equipment Manufacturing, formed a specialized technical team to precisely control the dimensions of various components of the reactors, strictly ensure the quality of welding and the success rate of flaw detection, and carefully review any changes that occurred during the equipment manufacturing process. This was done to ensure that both reactors were delivered and accepted to high standards by the scheduled dates. The successful installation of the core reactor not only marks a breakthrough in the construction of the acrylic acid plant but also lays a solid foundation for the overall progress of the project.
