【Major Industrial Equipment in the Chemical Industry】044-World’s Largest SD-Patented Ethylene Oxide Reactor
Thread Content
The past decade has been a period of rapid development for 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 localization of such equipment. We invite everyone to share their insights and engage in discussions, to cheer for Made in China and to support the development of chemical processing equipment! *********************************** On October 9, 2021, the world’s largest SD-patented ethylene oxide reactor, manufactured by China National Nuclear Corporation Dalian Nuclear Power Petrochemical Company, was completed and put into operation. The successful manufacture of this equipment has once again set a new world record for the production of SD patent ethylene oxide reactors, indicating that China’s manufacturing technology for ultra-large-scale petrochemical equipment remains on par with international standards. It further demonstrates China National Heavy Machinery Corporation’s capability in technological innovation as a key player in the field of heavy industry, as well as its strength in carrying out large-scale engineering projects. The SD patented ethylene oxide reactor manufactured by China National Heavy Machinery Corporation is the core equipment for the Shenghong Petrochemical Integration Project, which is a key project under the petrochemical industry development plan. The inner diameter of this equipment reaches φ8200 millimeters, its weight is 1242 tons, and it has as many as 17,867 heat exchange tubes.
Faced with numerous challenges such as the reactor’s extremely large size, heavy weight, and thick walls, its complex internal structure, and the great difficulties associated with welding, China National Heavy Machinery Corporation strived to achieve \"high starting points, high standards, and high quality.\" The engineering and technical personnel as well as the operators on the front line utilized their intelligence and creativity, showed great determination in overcoming difficulties, and focused on meeting project deadlines. By emphasizing quality while advancing work progress, they adopted a approach of \"daily tracking, weekly coordination, monthly evaluation, and quarterly analysis.\" They conducted numerous simulations to further refine the technical solutions, implemented strict project management, adhered to technical specifications, and maintained rigorous quality control. As a result, they were able to overcome the challenges posed by an extremely large diameter and a large number of tubes, and successfully completed the construction of the world’s largest SD-patented ethylene oxide reactor, making a significant contribution to China’s petrochemical equipment manufacturing industry.
Recently, the world’s largest SD-patented ethylene oxide reactor, manufactured by China National Nuclear Corporation Dalian Nuclear Power Petrochemical, was completed. The successful manufacture of this equipment has once again set a new world record for the production of SD patent ethylene oxide reactors, indicating that China’s manufacturing technology for ultra-large-scale petrochemical equipment remains on par with international standards. The high-end, extra-long and extra-thick SA302GrC container plates for the petrochemical industry, produced by Hebei Iron and Steel Wu Gang, are used exclusively in this reactor, contributing to the localization of steel used in petrochemical equipment in China.
