The largest domestically produced air compressor turbine has successfully passed testing in the "oil to coal" project at Anqing Chemical Fertilizer. All performance indicators have met the design specifications, marking a significant milestone in the localization of large-scale, continuous, and high-efficiency air compressors. This achievement breaks the long-standing monopoly of foreign companies in China's large-scale air separation equipment market, which had previously relied heavily on imports. It demonstrates that China's air separation equipment manufacturing industry has now reached international advanced levels.
The air separation unit installed in the "oil to coal" project at Anqing Fertilizer is currently the largest homegrown unit in China. Its key component, the air compressor, is also the largest independently designed and innovated unit in the country. The turbine has a rated power of 47,860 kW, and the axial length of the entire unit reaches 23 meters. The system features a large flow rate, numerous mechanically connected components, multiple control points, and complex interdependencies between different parts, making its design and construction extremely technically challenging.
This breakthrough not only showcases China's growing capabilities in heavy industrial equipment but also highlights the country's commitment to technological self-reliance and innovation. With this successful project, Chinese manufacturers are now better positioned to compete globally, reducing dependency on foreign technology and opening new opportunities for domestic and international markets alike.
