Where are the main applications of industrial gases

There are many types of gas products, which can be roughly divided into two categories: general industrial gases and special gases. The general industrial gas has a large production and sales volume, but the purity requirements are not high. Although the production and sales volume of special gases are small, they have extremely strict requirements on the purity or composition of different special gases, the maximum allowable content of harmful impurities, and the packaging, storage and transportation of different special gases according to different uses. They are high-tech and high value-added products. . Generally, special gases can be divided into three categories, namely high-purity or ultra-high-purity gases, standard calibration gases and mixed gases with specific compositions. As an important basic raw material for modern industry, gas products have a wide range of applications. A large number of commonly used gases are used in metallurgy, steel, petroleum, chemical, machinery, electronics, glass, ceramics, building materials, construction, food processing, medicine and medical care. Or specialty gases.

Because of the large application coverage of gas products, the production and supply of gas is generally the same as power supply and water supply. As the infrastructure of the industrial investment environment, it is regarded as the "lifeblood" of the national economy and listed as the public utility industry.

With the rapid development of my country’s national economy, the scope of application of gas products has continued to expand, the consumption continues to increase, new products continue to be introduced, purity continues to increase, and market demand continues to expand. The growth rate of output value far exceeds the growth rate of the gross national economy during the same period, reaching Annual growth rate of 12%. The annual sales of the national gas products market is about 40 billion yuan. Although the total output value of the gas industry does not account for a large proportion of the GDP of the national economy, it is important for the current rapid development of microelectronics, aerospace, bioengineering, new materials, precision metallurgy, environmental science and other high-tech sectors. The impact is the indispensable raw material gas or process gas in these sectors. It is precisely because of the needs and promotion of various emerging industrial sectors and modern science and technology that gas industrial products have achieved remarkable development in terms of variety, quality and quantity.
