Air separation equipment petrochemical market share doubled

The reporter learned from the Gas Separation Equipment Branch of the China General Machinery Industry Association on June 9 that the structure of the air separation equipment market in China has been quietly changing in the past three years. Although the market is still dominated by the metallurgical industry, the petrochemical and fertilizer industries are fast. Development, the air separation equipment market share in the petrochemical industry has increased from 14.5% in 2002 to about 30% in 2005. In addition, the trend of large-scale development of air separation equipment is more obvious, and manufacturing technology is also becoming more mature.

It is reported that of the 25 sets of air separation equipment over 30,000 grades that were signed on the domestic market in 2005, 10 sets were used in the petrochemical and fertilizer industries; 39 sets of air separation equipment of more than 20,000 grades were signed in the industry, among which 30,000 grades were With 25 sets of large-scale air separation plants, it is the fastest growing year for the large air separation equipment market.

Experts believe that there are three main reasons for promoting the development of large-scale air separation facilities in China: First, after China's macro-control of the steel industry, the metallurgical industry will implement joint reorganization to bring new market demand; Second, the development of petrochemical and fertilizer industries, especially The development of coal-to-oil, large-scale chemical fertilizers, and large ethylene projects has opened up new development opportunities for large-scale air separation plants. Third, China’s large-scale air separation equipment manufacturing technology has become increasingly mature and its cost-effective advantages have won more and more. Domestic users' trust.

In addition, China's air separation equipment manufacturing industry has made new breakthroughs in new product development and new technology applications, and promoted the development of China's air separation equipment manufacturing technology. Among them, two sets of 63000m3/h air separation equipment provided by Hangyang Oxygen Co., Ltd. for Iran are the largest grade air separation equipment independently developed in China. The device adopts full low pressure molecular sieve purification and adsorption, medium pressure air turbo turboexpander. The oxygen internal compression process of structured packing, full packing argon, and full-flow Argon-making technology fills the gap in the independent development of 60,000 grade air separation plants in China; the 52,000m3/h air separation plant provided for the 500,000 tons/year methanol project of Zhongyuan Dahua , The use of air pressure, oxygen and nitrogen double pump compression process, is currently China's largest domestic air separation equipment. According to another report, the air separation plants used in chemical companies with oxygen pressures of 4.6 MPa or more have adopted a liquid oxygen pump compression process. The oxygen extraction rate can reach 95% to 97%, and the argon extraction rate can reach 70%. ~ 80%, these technical indicators have reached the international advanced level.
