Our company is a gas and energy company. We would like to introduce industrial air separation gases "oxygen, nitrogen, and argon" that are separated from air. 【1. Nitrogen Gas】 It makes up about 80% of the air and is characterized by being a non-reactive gas at -196°C in liquid form. It is widely used for purposes such as freezing food, preventing oxidation, and cooling metals. 【2. Oxygen Gas】 It has the property of supporting combustion and contributes to high-temperature combustion and the maintenance of life in organisms. Applications include steelmaking, where time reduction and environmental improvement are needed, and aquaculture, which requires high-concentration oxygenated water. 【3. Argon Gas】 It is a non-reactive gas that makes up just under 1% of the air. Because it remains inert even at high temperatures, it is used as a filling gas in fluorescent lamps. In recent years, it has also been registered as a food additive and is gaining attention, including its use as a filling gas for food products in the future.
