Quick Facts About Industrial Gas Products
I. Definition and Classification of Industrial Gases
Industrial gases refer to substances that exist in a gaseous state under standard temperature and pressure and are stored and transported in the form of cylinders, Dewar flasks, or pipelines after being compressed or liquefied. Based on their intended use and purity, they can be categorized into the following two types:
Bulk Gases: Gases with purity requirements below 5N (99.999%), produced in large quantities, such as oxygen, nitrogen, argon (air separation gases) and acetylene, carbon dioxide (synthesis gases).
Specialty gases: These gases have high purity requirements and are used in specific applications, such as electronic specialty gases, high-purity gases, and standard gases. Examples include high-purity hexafluoroethane and high-purity carbon dioxide.
Classified by chemical properties:
Highly toxic gases—such as chlorine and ammonia—can cause poisoning or even death upon entering the human body.
Flammable gases—such as hydrogen and acetylene—pose risks of combustion and explosion.
Auxiliary combustion gas: Such as oxygen, which does not burn on its own but can intensify a fire.
Non-combustible gases—such as nitrogen, carbon dioxide, and argon—are chemically stable but can cause asphyxiation.
II. Core Application Areas of Industrial Gases
Traditional industries:
Metallurgy: Oxygen is used to enhance combustion efficiency, nitrogen serves as a protective gas, and argon is used for welding protection.
Chemical industry: Hydrogen serves as an energy carrier, carbon dioxide acts as a protective gas, and nitrogen is used in the production of synthetic fibers and fertilizers.
Mechanical manufacturing: Acetylene and propane are used for cutting and welding, while oxygen is used for metal heat treatment.
Emerging fields:
Electronics Industry: Specialty electronic gases are critical materials in semiconductor manufacturing, used in processes such as lithography, etching, and doping. They account for 13% of wafer fabrication costs.
Medical and Healthcare: Oxygen is used in hyperbaric oxygen therapy, liquid nitrogen is used for cryopreservation of biological samples, and helium is used in magnetic resonance imaging.
New energy: Hydrogen is used in fuel cells, while carbon dioxide is used in coal gasification and coal liquefaction.
III. Standards for the Storage and Transportation of Industrial Gases
Storage requirements:
Gas cylinders should be stored upright, equipped with anti-tip measures, and kept away from open flames and heat sources.
The distance between flammable gases (such as acetylene and methane) and oxygen cylinders must be greater than 5 meters, and the distance from open flames must be no less than 10 meters.
Liquefied gases (such as liquid nitrogen and liquid carbon dioxide) must be stored in Dewar flasks and are strictly prohibited from being stored horizontally.
Transportation specifications:
Handle with care and avoid throwing, sliding, rolling, or subjecting to severe impacts.
Flammable gases and oxidizing gases must be transported in separate vehicles using specialized vehicles for hazardous chemicals.
When performing mobile operations, oxygen cylinders and acetylene cylinders must be separated by partitions made of non-combustible materials.
IV. Precautions for Safe Use
Pre-operation check:
Confirm that the cylinder’s paint color, inspection date, appearance, and safety devices (such as pressure regulators and flame arresters) are all in good condition.
Use soapy water to check for gas leaks at connections; never use damaged equipment (such as hoses or welding torches).
Environmental requirements for use:
Avoid using inert gases (such as nitrogen and carbon dioxide) in enclosed spaces to prevent suffocation.
When welding, it is necessary to equip with backflow prevention devices such as check valves and non-return valves.
Emergency Handling:
Immediately close the valve and ventilate the area when a leak is detected. Absolutely prohibit open flames or static sparks.
When there is a flammable gas leak, do not turn on electrical appliances or make phone calls.
V. Industry Trends and Market Size
Growing demand:
The share of traditional industries (steel and chemicals) is declining, while demand in emerging sectors (electronics and healthcare) is rising rapidly.
The Chinese industrial gas market is expected to achieve an annual growth rate of over 11% in the next five years.
Technological Development:
The supply format has expanded from bottled products to on-site gas generation and pipeline delivery, reducing logistics costs.
The purity requirement for electronic specialty gases reaches over 99.9999%, driving advancements in technologies such as cryogenic separation.
Global Landscape:
Germany’s Linde and France’s Air Liquide account for about 40% of the global market, while domestic companies (such as Hangyang and Huater Gas) are accelerating their efforts to catch up.
