Industrial gas is used for industrial production and manufacturing gases, a wide variety of applications, can be divided into bulk gas and specialty gas according to the different preparation technology and application fields. Common industrial gases include oxygen, nitrogen, argon, hydrogen, carbon dioxide, propane, acetylene, etc., which are usually stored in large cylinders and distributed accordingly after mass production.
Industrial gases are used in energy conservation and environmental protection, high-end equipment manufacturing, food, metallurgy, chemical industry, machinery manufacturing and other industries, which can be said to cover almost all industrial fields. In recent years, the market prospects are broad, in the semiconductor, optical fiber communication, photovoltaic, new energy, LED and other emerging industries, the importance of industrial gases is more and more significant.
The process of producing high purity industrial gases from ASU (Air Separation Unit) is based on the difference in boiling point of different gases. The whole process is mainly divided into five steps: the first step is air compression, the ASU device sucks in the surrounding air, compresses the air, makes it smaller, and raises the pressure, just like a pump inflates a tire. Prepare for the second step of air purification, because there are impurities in the air such as moisture, carbon dioxide and dust, which will freeze at low temperatures and have the potential to clog the equipment. Therefore, the air passes through the heavy filtration device of the ASU system to remove the impurities and achieve the purpose of purifying the air. Next is the cooling and liquefaction of the air, the purified air into the heat exchanger, and finally cooling, reaching a temperature of nearly liquid.
After distillation separation, it is also the most critical step of the whole process, using the different characteristics of different gas boiling points, the liquid air is poured into the rectification tower, so that they are evaporated and condensed in different layers at different heights, so as to collect different gases respectively. For example, nitrogen is at the top, because it evaporates most easily, while oxygen is easier to liquefy, so it sinks to the bottom, and argon is in the middle.
The final step is to further purify the product, Fullcryo provides 5N (99.99%) of high purity industrial gas, and also supports the way to build a factory to help companies in need of industrial gas manufacturing. Purified industrial gases are stored in high-pressure cylinders, cryogenic storage tanks, or delivered directly to customers via pipelines.
Industrial gases may sound very foreign, but they actually affect our daily lives all the time. For example, the food bag filled with nitrogen (N2), the purpose is to prevent food oxidation deterioration, is widely used in the field of food preservation. The main component of carbonated drinks is carbon dioxide (CO2), which is also used to make dry ice for staging and food refrigeration. Oxygen (O2) provides respiratory support and is commonly used in hospitals and high altitude and diving operations.
Industrial gas is likened to the “blood of industry”, the most widely used in traditional industrial fields, bulk gas for metallurgy, chemical, steel and other industries to provide important support. For example, in steel smelting, oxygen is used to make steel in blast furnaces to improve combustion efficiency; Use the characteristics of nitrogen inert gas to improve the purity of the metal, and use the excellent stability of argon, which is an indispensable protective gas for welding. In the chemical industry, hydrogen is widely used in petroleum refining, ammonia synthesis and hydrogenation reactions to improve fuel quality.
In emerging industries such as semiconductors and new energy sources, purity and stability are extremely high. Special gases are usually widely used. For example, sulfur hexafluoride (SF₆) was used as an insulating gas in high voltage electrical equipment. With advanced air separation and high-purity gas production technology, Fullcryo provides 5N level ultra-high-purity gas, and customized professional supply solutions to help the stable development of high-end manufacturing industry.
Industrial gas market demand is stable and continues to increase. Statista data show that in 2024, the total value of the global industrial gas market is about 1.67 billion US dollars, and it is expected that by 2029, the global market value will be added by 2.07 billion US dollars, this growth is mainly benefited from the strong demand of metallurgical, chemical, medical, electronics, semiconductors and new energy industries.
According to different supply methods, the gas supply mode of the industrial gas industry can be divided into bottled gas mode, liquid storage tank gas mode, and on-site pipeline gas production mode. In the gas production business market, the value of on-site supply accounts for the largest proportion. With the rapid development of emerging industries, the demand for special gases based on bottled gas is expected to continue to grow, and the proportion of bottled gas is expected to increase.
As an international leading industrial gas and equipment supply company, Fullcryo provides on-site gas supply mode for ASU equipment, helps customers build on-site air separation devices, and produces on-site industrial gas supply for customers. At present, it has cooperated with companies involved in chemical, metallurgy, food industry, semiconductor industry and other industries, with more than 100 sets of air separation equipment for 30 years + operating experience. To provide users with safe, stable, long cycle, full load, high-quality gas supply and service, for users to save operating costs, improve economic and social benefits.
The industrial gas industry has broad prospects, whether it is investing in the construction of gas production equipment, or providing customized supply services, it needs accurate market positioning and efficient operation management. First, companies need to identify their target markets and assess demand trends for bulk gases (e.g., oxygen, nitrogen, argon) or specialty gases (e.g., electron grade helium, hydrogen). Second, select the right air separation unit (ASU) or other gas making equipment to ensure that production efficiency and gas purity meet industry standards.
At the same time, it is crucial to build a safe and reliable supply chain, optimize energy efficiency management, and establish long-term stable customer cooperation. Fullcryo provides comprehensive support from investment planning, equipment selection, plant construction to operation management to help enterprises efficiently start industrial gas business, quickly enter the market, and achieve sustainable development.
