On December 20, the cyclohexene separation tower, a key equipment for the 1# 320,000-ton/year cyclohexanol plant constructed by the East China Branch of China National Chemical Engineering Group Corporation, was successfully hoisted into place. The cyclohexene separation tower is the core static equipment of the plant. It has a diameter of 6.4 meters and a total height of 96.65 meters; its weight is 473.5 tons, and with the additional auxiliary facilities, the total weight rises to 602.486 tons. It is the tallest tower in the cyclohexanol unit of the high-end new material adipic acid production project, making its installation extremely difficult and requiring sophisticated technical skills. The project adopted a dual-crane coordination lifting scheme of \"main crane + auxiliary crane\", deploying a 2,000-ton main crane in conjunction with a 400-ton auxiliary crane to successfully complete the lifting task, with various parameters setting new records for the project’s lifting operations. As part of Zhejiang Petrochemical Co., Ltd.’s projects for high-end new materials as well as the renovation and upgrading of its refining and chemical integration facilities, the high-end new materials adipic acid production project, once operational, will be able to produce 450,000 tons of adipic acid, 320,000 tons of cyclohexanol, and 280,000 tons of hexamethylenediamine per year, thereby helping to fill the gap in the supply of high-end chemical products in China. The main products of this project can be used to manufacture important materials such as nylon 66, special engineering plastics, and polyurethanes. It is expected that the self-sufficiency rate for these products will exceed 70%, which will help reduce the high dependence on imported high-end chemical materials and enhance the ability to control the industrial chain and supply chain independently. Next, the project team will make every effort to advance the subsequent construction tasks, ensuring that the project’s objectives are achieved on schedule. This will enable us to provide better services to our clients, and contribute to the high-quality development of China’s chemical industry through the efforts of 16th Chemical Construction Group.
