1. Industrial gas definition:
In my country's industrial production, products that are gaseous at normal temperature and pressure are collectively referred to as industrial gas products. A bottled compressed liquid gas, which is in a gaseous state at normal temperature and pressure. There are many types of gas, and it is mainly used in various industrial manufacturing.
2. Industrial Gas Applications:
Industrial gas products are important basic raw materials for modern industry. Industrial gases are called the "blood" of industry. With the rapid development of CHINA's economy, industrial gas, as one of the basic industrial elements of the national economy, has become increasingly prominent in its important position and role in the national economy. Its application range is widely distributed in: petroleum, chemical industry, metallurgy, steel, machinery, electronics, electric power, glass, ceramics, building materials, food, medicine, medical treatment, urban residents and other fields.
According to the "2013-2017 CHINA Industrial Gas Industry In-depth Research and Investment Forecast Analysis Report", after 2000, the domestic industrial gas industry entered a stage of rapid development. From 2006 to 2007, the growth rate of the industry's total output value was above 10%. The total annual output value of the industry is nearly 70 billion yuan.
my country's industrial gas market has a vast space, and many fields have entered a stage of rapid growth. The downstream application fields of the industrial gas industry continue to expand. From 2002 to 2012, the demand for energy, environmental protection, and medical care grew faster than traditional steel and non-ferrous metals, coupled with the new coal chemical industry, especially the vigorous development of coal-based natural gas, energy conservation and emission reduction , Reduction of energy consumption and the reduction of sulfur content in gasoline and diesel required by the National Three National Standards will accelerate the growth of demand for industrial gases during the "Twelfth Five-Year Plan" period.
In the next five years, my country's industrial gas market will maintain a growth rate of at least 11%, and reach sales of more than 120 billion yuan by 2016. The outsourcing share of the industrial gas market will further increase from 42% in 2008 to 50% in 2015.
3. Classification of industrial gases:
(1). According to chemical properties
①Toxic gas: such as: chlorine gas (CL2), ammonia gas (NH3)
②flammable gas: such as: hydrogen (H2), carbon monoxide (CO)
③ Combustion-supporting gas: such as: oxygen (O2)
④ Non-combustible gas: such as: nitrogen (N2), carbon dioxide (CO2), argon (Ar)
In the national standard GB13690-1992, the above-mentioned 4 kinds of gases are divided into 3 sub-categories, namely 2.1 flammable gases, 2.2 non-combustible gases (including combustion-supporting gases), 2.3 toxic gases
(2). According to the composition
①Pure gas of a single type of gas.
②A mixture of binary or multi-element gases.
4. Hazardous properties of industrial gases
① Combustibility - combustible gas
② Toxicity - poisonous gas
③Asphyxiation-hypoxia
④Corrosivity--Moisture has a great influence on industrial gas medium, and it is easy to produce corrosive chemical substances
⑤ explosive - physical explosion and chemical explosion.
Korno Standard Gas System
There are many types of gas products, which can be roughly divided into two categories: general industrial gases and specialty gases. The production and sales of general industrial gases are large, but the requirements for purity are not high. Although the production and sales of special gases are small, according to different uses, there are very strict requirements on the purity or composition of different special gases, the maximum content of harmful impurities, and the packaging, storage and transportation of products, which are high-tech and high value-added products. . Generally, specialty 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 of modern industry, gas products have a wide range of applications. In metallurgy, steel, petroleum, chemical industry, machinery, electronics, glass, ceramics, building materials, construction, food processing, medicine and medical treatment, a large number of commonly used gases are used or specialty gases.
