In recent years, the overall output of air separation equipment has declined, and the trend of large-scale and localization is obvious.
Air separation equipment is one of the major national equipment, which can separate and produce a variety of industrial gases, which are widely used in machinery, metallurgy, petrochemical, new coal chemical industry, building materials, aerospace and medical and other important national economic fields. At present, the application fields of air separation equipment are mainly the metallurgy and chemical industries, and the demand for the industrial gases produced by industrial air separation unit for the two major fields accounts for about 60%. At the same time, the demand for industrial gases from emerging industries such as new coal chemical, medical and electronics industries is also increasing.
At present, internationally well-known air separation equipment companies include German Linde Company, French Air Liquide and other large multinational groups. There are more than ten domestic companies engaged in the production of air separation equipment, mainly including Hangzhou Hangyang Co., Ltd., Kaifeng Air Separation Group Co., Ltd., Sichuan Air Separation Equipment (Group) Co., Ltd. and other joint venture or sole foreign corporation like Air Liquide (Hangzhou) Company and Linde (Hangzhou) Company.
From 2010 to 2018, the output of gas separation and liquefaction equipment (air separation equipment) in our country showed a trend of first increase and then decrease; from 2010 to 2014, the output of gas separation and liquefaction equipment in our country increased from 9,450 to 70,394; Production has fallen from 2015, with an output of 46,016 units in 2018.
Industry experts pointed out that the domestic market share of domestically produced air separation equipment has continued to increase. At present, domestically produced air separation equipment - Air Separation Plant of 60000m³/h and below has a market share of more than 90%, and the oxygen generation equipment capacity ranks first in the world; in the market for above 60000m³/h, domestic enterprises have reached the level of competition with foreign-funded enterprises, for example, Hangyang's domestic market share of air separation equipment above this level has reached more than 50%.
At present, as the overall scale of coal chemical industry and oil refining projects is not large, the coal deep processing industry will have greater development, and many major projects are still under review. In addition, the project investment is large and the cycle is long. In the next few years, China Coal The chemical market will still have demand for large and super large air separation equipment. During the "13th Five-Year Plan" period, our country will also have 1 million tons of indirect liquefaction in Yitai Yili, 2 million tons of indirect liquefaction in Yitai Ordos, 2 million tons of indirect liquefaction in Yitai Xinjiang, and 4 million tons of indirect liquefaction of Shenhua Ningxia Coal (Phase II) , Shenhua Ordos 3.2 million tons (phase II) direct liquefaction, Yankuang/Yanchang Yuheng 4 million tons indirect liquefaction projects have been completed and put into production one after another. By the end of the "Thirteenth Five-Year Plan", our country is expected to have a total coal liquefaction capacity of 28.18 million tons per year. Based on the calculation of about 70% of finished fuel oil products, there will be 20 million tons of coal-to-liquid products per year.
The downstream applications are extensive. Metallurgy and chemical industries are currently the mainstays. In the future, the proportion of gas consumption in the emerging dispersed retail market will further increase.
Due to the inherent physical and chemical properties of industrial gases, they occupy a pivotal position in the national economy and penetrate almost all walks of life. They are widely used in metallurgy, steel, petroleum, chemical, machinery, electronics, glass, ceramics, building materials, and construction. , Food processing, medical and medical industries.
