From November 10th to 11th, the 1-million-ton-per-year high-end chemical materials project developed by Shaanxi Yueneng Fine Chemicals Company reached an important milestone: the first and second oxidation reactors of the acrylic acid production unit were successfully lifted into place. This marks the entry of the project construction into the critical phase of equipment installation, laying a solid foundation for the smooth progress of subsequent stages. It is reported that as the core equipment of the acrylic acid plant, the two oxidation reactors lifted this time perform the critical function of oxidation reactions. The equipment is large in size, with a diameter of 7.6 meters per unit, making it difficult to lift; the first oxidation reactor is 9.9 meters long and weighs 300 tons, while the total weight to be lifted is 348 tons ； The length of the second oxidation reactor is 8 meters, its weight is 235 tons, and the total lifting weight is 256 tons. A 650-ton crawler crane was used as the main lifting device throughout this hoisting operation, and the process proceeded smoothly and in an orderly manner. Ultimately, the two reactors were accurately positioned, and the lifting task was successfully completed. To date, the acrylic project has entered a critical phase in which the final stages of the civil structure construction and equipment installation are carried out simultaneously.
