【Major Chemical Equipment Innovations】From 1989 to 2013, Dalian Jinzhong manufactured the world’s first ultra-large-scale Fischer-Tropsch synthesis reactor

Thread Content

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! *********************************** Recently, the world’s first ultra-large Fischer-Tropsch synthesis reactor, developed by Dalian Jinzhou Heavy Machinery Co., Ltd. for China Shenhua Ningxia Coal Industry Group, was delivered in Yinchuan. This has not only made significant contributions to the localization and domestic production of large-scale coal chemical equipment in China, but it also signifies that Dalian Jinchong has become a world-leading manufacturer of petrochemical equipment. In August 2012, thanks to its strong overall capabilities, Dalian Jinchong secured a contract from China Shenhua Group for the manufacturing of equipment worth 640 million yuan, including four Fischer-Tropsch synthesis reactors. The two parties agreed to complete all work and make deliveries by March 2014, with the first Fischer-Tropsch synthesis reactor to be delivered by the end of October 2013. Due to its excessive weight, height, and length, this equipment could not be transported by road. Dalian Jinchong utilized the factory facilities owned by Shenhua Group in the Ningdong Heavy Equipment Manufacturing Plant, investing 85 million yuan to acquire nearly 500 pieces of manufacturing equipment in order to produce this ultra-large Fischer-Tropsch synthesis reactor. At the request of its customers, it managed to complete the world’s first ultra-large coal-to-oil Fischer-Tropsch synthesis reactor four months ahead of schedule. The Fertro synthesis reactor was listed by the National Development and Reform Commission as one of the 15 demonstration projects for advanced coal processing under the 12th Five-Year Plan; it is the core equipment in Shenhua Ningxia Group’s plant for the indirect liquefaction of coal into petroleum products, with an annual production capacity of 4 million tons. This Fischer-Tropsch synthesis reactor weighs 2,200 tons, has a diameter of 9.6 meters and a length of 61.5 meters, with an annual production capacity of 4 million tons. Previously, the world’s largest Fischer-Tropsch synthesis reactor for coal-to-oil production was also manufactured by Dalian Jinzhong, with an annual processing capacity of 160,000 tons. The production process used in Fischer-Tropsch synthesis reactors involves first converting coal into gas and then into a liquid form, that is, oil. This process is more environmentally friendly and consumes less water. As a result, the structure of the reactor becomes more complex, with special material requirements and high difficulties in design and manufacturing.
