A contract for the first domestic ethylene oxide reactor

On October 8, China's No.1 Heavy Machinery Group Company signed a manufacturing contract with Dalian New Group, which will officially form the first domestically-made ethylene oxide reactor, which is expected to break the long-term monopoly of foreign companies on this major equipment. pattern.

The reactor has a total weight of about 500 tons and an ethylene oxide production capacity of 60,000 tons/year. It adopts the US SD company's patented technology and the construction design and manufacture are all completed by one weight. At present, the development of this reactor has entered the design stage and it is scheduled to be completed in October next year. The ethylene oxide reactor will be used in the Bohai Biochemical Project in Jilin City, a wholly-owned subsidiary of Dalian New Group.

According to Cai Lianzhong, a deputy general manager of China’s heavy industry, ethylene oxide is an important chemical raw material that can generate nearly 1,000 kinds of products, and it is toxic and explosive, difficult to transport and import. At present, China’s annual supply and demand gap of ethylene oxide It is 3 million tons. Ethylene oxide reactors are key equipment for the production of ethylene oxide and are key equipment for the petroleum and chemical industries. At present, China has 1.3 million tons/year ethylene oxide production capacity, but the reactors used are all imported equipment, and its manufacturing technology is monopolized by Germany, Japan, Italy and India. The first domestically produced ethylene oxide reactor represents a new step in the production capacity and manufacturing level of large-scale pressure vessel manufacturing, which can greatly increase the manufacturing level and international competitiveness of China's heavy machinery and equipment.
