The birth of the first domestically produced 20,000 tons maleic anhydride reactor
According to reports, the significance of successful development of maleic anhydride reactors lies not only in the localization of production equipment, but also in the development of other series of large-scale tubular oxidation reactors similar in structure to maleic anhydride reactors and similar in structure. Corresponding breakthroughs.
The reporter learned from Shanghai Huayi that this 20,000-ton maleic-anhydride reactor was independently developed by Shanghai Coatings Co., Ltd., a subsidiary of the group, and Shanghai Chemical Equipment Co., Ltd. In the early stage of development, the two companies have accumulated a large amount of first-hand information in core technology development, software design and simulation tests such as processes and equipment, among which a number of proprietary technologies have reached the domestic advanced level.
In this 20,000-ton domestic maleic anhydride reactor manufacturing process, researchers solved a number of technical problems. The project has overcome many technical difficulties such as large-scale tubular reactor anti-welding deformation, precise positioning of pipes, leakage prevention of welded joints, and lifting. At present, one patent application has been completed, and the remaining several patent applications are also under implementation.
Maleic anhydride is an important fine chemical product with a wide range of application values. It is necessary to use maleic anhydride in the production of environmentally friendly coatings for life. In the past, maleic anhydride used domestically relied heavily on imports. Maleic anhydride production equipment was also monopolized by foreign chemical machinery companies.
Shanghai Huayi Chemical Equipment Co., Ltd., which undertakes 20,000 tons of maleic anhydride reactor manufacturing projects, is a professional enterprise with 50 years of experience in chemical equipment manufacturing. It has design, manufacturing licenses for pressure vessels of types I, II, and III, and ASME design for the United States. U and U2 certificates are manufactured. Among them, the plate-type fertilizer high-pressure vessel was rated as high-quality product of Shanghai and the former Ministry of Chemical Industry. One ton of liquid chlorine cylinder won the national silver prize. The annual output of 200,000 tons of methanol equipment key equipment low-temperature methanol washing sets of special pressure vessels obtained the national Science and Technology Achievement Award.
