In terms of the development of large-scale air separation plants in China, the number of large-scale air separations has reached an absolute majority in the world. The ratio of 60,000-class air separations to global air separation is greater than 75 percent; the domestic monomer scale has reached 100,000-scale. In the market demand of the past three years, the proportion of extra-large air separations accounted for the vast majority.
The characteristics of the construction of air separation plants in China in recent years are as follows:
First, attach importance to the stability of equipment units, because it limited by the conditions of transportation and installation is difficult.
Second, the equipment installation time is short, there are loopholes in management.
Three, Some areas in which the environment are poor, such as serious pollutants in the chemical industry area, lack of water, and large sandstorms in the northwestern region.
Fourth, the difference level of installation team is uneven.
Five, the demand for coal chemical industry is high, the demand for iron and steel metallurgy is low, the coal chemical industry is more concerned with stability, and steel is more concerned with the energy saving of operation.
Six, The relocation of the iron and steel industry has created a new wave of demand, but the overall volume is small, and the energy-saving transformation has increased.
With the rapid development of modern technology, the future development of air separation equipment will show the following trends:
First, large-scale, clustering;
Second, the core technology gradually localized;
Third, refinement, for different application areas, the need to develop and match with efficient energy-saving process;
Fourth, highly automated, intelligent (such as automatic load change, reduce product release rate, minimize manual operations, the use of high-speed Internet technology to gradually establish a remote monitoring system, real-time collection of air separation equipment operating data, the use of big data analysis Give users the best advice, etc.)
Professor Li Huazhi, a senior expert in the field of metallurgical oxygen production in China, pointed out that the metallurgical oxygen industry should pay attention to the following aspects:
First, we must focus on operational optimization, attach importance to environmental issues, and closely link production operations with the environment.
Second, we must pay attention to practical energy-saving transformation.
Third, the oxygen plant of iron and steel enterprises should pay attention to the future development trend.
