The development of Chinese air separation equipment, as a whole, the number of large-scale air separation plant (Asu) is with the absolute majority in the world, and the proportion of 60,000 grade air separation is more than 75% of the global air separation; the domestic single unit scale has reached the grade of 100,000. Among the recent three years’ market demand, the proportion of super-large air separation systems accounted for the vast majority.

In recent years, the characteristics of Chinese air separation equipment’s   construction ( including Oxygen Generation Plant, Nitrogen Generation Plant and Argon Generation Plant ) are as follows: First, it attaches importance to the stability of the supporting units, which is difficult to install due to restrictions on transportation conditions. Second, the equipment installation time is short and there are loopholes in management. Third, the environment of some areas is poor, such as serious pollutants in the chemical industry zone, water shortage, and heavy sandstorm in the northwest. Fourth, the level of the installation team is uneven. Fifth, coal chemical industry demand is high, steel metallurgy demand is small, coal chemical industry pays more attention to stability, and steel industry pays more attention to energy saving in operation. Sixth, the relocation of the iron and steel industry has created a new wave of demand, but the overall amount is not large, and energy-saving transformation has increased.

With the rapid development of modern science and technology, the future air separation equipment will present the following development trends: one is large-scale and clustered; the second is the gradual localization of core technology; the third is refinement, which needs to be developed to match different application fields High-efficiency and energy-saving technology; the fourth is highly automated and intelligent (such as fully automatic load change, reduce product release rate, minimize manual operation, and use the rapid development of Internet technology to gradually establish a remote monitoring system to collect operating data of various air separation equipment in real time. Use big data analysis to provide users with the best advice, etc.).
