Red May for chemical industry workers! Reply reward! ---------------------------------------------- The past decade has been a period of rapid development in China’s chemical industry, marked by the emergence of many new processes, products, and equipment. There has also been significant progress in China’s chemical processing equipment, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and greater use of domestic equipment. We invite everyone to share their insights and discuss these topics together; let’s cheer for Made in China and support the development of chemical processing equipment! On December 1, 2018, the construction of two acrylonitrile (AN) reactors for Jiangsu Sierbang Petrochemical Co., Ltd.’s acrylonitrile capacity expansion project was successfully completed. This reactor is the core equipment for the acrylonitrile (AN) unit in Jiangsu Sierbang Petrochemical Co., Ltd.’s acrylonitrile capacity expansion and technological upgrade project. It has an inner diameter of Φ9550 mm, a total length of approximately 33,845 mm, and a total weight of around 482.7 tons. The main material used for its construction is 15CrMoR. The internal components of the reactor have a complex structure, and their installation must be carried out in a specific sequence. The coaxiality between the distribution tubes of the propylene-ammonia distributor and those of the air distribution plate must be checked and verified in strict accordance with the requirements specified in the drawings and technical agreements; as a result, the manufacturing and inspection processes are extremely challenging. After more than 7 months, the delivery was successfully completed with both quality and quantity met.
