[Ten years of development of chemical equipment] 40,000 heat pipes will be replaced from 1004 to 2023. The largest monomer maleic anhydride reactor in China
Thread Content
Chemical equipment has developed greatly in the past ten years, praising the prosperity of China in the prosperous world. It is more exciting with everyone's participation. The ocean is more exciting with you. Everyone is welcome to participate in the forum to communicate and discuss the high temperature in July. Pay attention to fire prevention. On July 6, 2023, at the Jinlong Heavy Duty Terminal in Zhangjiagang, the first batch of three maleic anhydride reactors produced by Zhangjiagang (Suzhou) Heavy Equipment Co., Ltd. was successfully shipped. The equipment has a maximum outer diameter of 11.4 meters, a monomer weight of 780 tons, and 40,000 internal heat pipes. It is currently the largest monomer maleic anhydride reactor in China. It is reported that the large-scale maleic anhydride reactors completed and delivered this time were customized for Hengli Petrochemical (Dalian) New Materials Technology Co., Ltd. A total of 12 units are used for the high-end new materials project of the maleic anhydride plant with an annual output of 4×210,000 tons.
Maleic anhydride is a basic organic chemical raw material with broad development and application prospects. “This equipment mainly uses the oxidation method to make maleic anhydride, and then uses maleic anhydride to make BDO, an important raw material for degradable plastics. Previously, equipment of the same process type mainly relied on imports from German manufacturers. However, the maleic anhydride reactor delivered this time was completed by Zhang Chemical Machinery from early design participation to manufacturing and inspection. During the use of the equipment, there are severe endothermic and exothermic reactions, and the working conditions are extremely harsh. There are as many as 40,000 heat exchange tubes arranged inside the maleic anhydride reactor. Such a large number of tubes places very high requirements on the design, welding and manufacturing of the reactor. Faced with the production of products with high standards and strict requirements, Zhang Chemical fully communicated with the design institute in the early stage to optimize the structural process and organized multiple technical briefings during the production process to allow the constructors to understand and master the technical requirements and manufacturing specifications. Finally, the inspectors focused on grasping the key points of quality. It is understood that the production of maleic anhydride reactors by Zhang Chemical Machinery lasted 11 months from the design and raw material procurement to the completion and delivery of the first batch of manufacturing.
