Hefei General Machinery Research Institute, along with other organizations in Anhui Province, has successfully developed and constructed a large-scale low-temperature ethylene spherical tank with independent intellectual property rights after three years of dedicated research and development. This breakthrough marks a significant milestone in China's domestic energy infrastructure and industrial technology.
An ethylene spherical tank is a critical storage component in ethylene cracking units, which are essential in the production of petrochemical products. These tanks operate under high pressure and extremely low temperatures, typically around -50°C, requiring highly reliable insulation systems to maintain stability and safety. The design, material selection, manufacturing, and construction of such tanks present numerous technical challenges, especially when dealing with low-temperature environments.
Through extensive research and innovation, Hefei General Machinery Research Institute and its partners have successfully addressed key technological and process challenges in the design, fabrication, welding, and heat treatment of large-scale low-temperature ethylene spherical tanks. They have independently developed comprehensive application technologies for manufacturing pressure vessels using -50°C low-temperature steel, enabling the full domestic production of such critical equipment.
This achievement led to the successful construction of China's first 2,000 cubic meter low-temperature ethylene spherical tank, breaking the long-standing reliance on imported technology for large-scale low-temperature ethylene storage solutions. The project not only enhances China's self-sufficiency in this field but also strengthens its position in the global petrochemical industry.
To date, the institute has signed cooperation agreements with major companies such as PetroChina Dushanzi Petrochemical, Jiujiang Petrochemical, and Tianjin Petrochemical, signaling strong industry support and future collaboration opportunities. This development is expected to drive further advancements in domestic energy infrastructure and reduce dependency on foreign suppliers in the long term.
