Product & service detail

 OXYGEN (O2)
 
1. Overview

Oxygen, represented by the chemical symbol O and atomic number 8, is a vital element in the periodic table. It exists predominantly as a diatomic molecule, O2, in its gaseous form. At extremely low temperatures, around -183°C, oxygen gas condenses into a bluish-colored liquid. Liquid oxygen occupies significantly less volume than its gaseous form under standard temperature and pressure conditions (15°C, 1,013 bar), making it practical for transportation and storage.
 

2. Properties

In gaseous form, oxygen is commonly compressed at high pressures of 150 bar or 200 bar for industrial use. It is also available in high-purity grades such as Oxygen 4.5, Oxygen 5.0, Oxygen 5.2, and Oxygen 5.5, which correspond to purities of 99.995%, 99.999%, 99.9992%, and 99.9995% respectively, used extensively in experimental analysis and medical applications.

3. Applications

— Industrial Applications:
Oxygen plays a crucial role in industrial processes due to its ability to enhance oxidation and combustion reactions. It is indispensable in the production of steel and iron in blast furnaces, as well as in glass and cement manufacturing. Additionally, oxygen finds application in water treatment and environmental processes, where it can be dissolved to enhance oxygen levels in fish tanks and facilitate aerobic conditions.

— Medical Applications:
In medicine, oxygen is essential for supporting respiratory functions in patients. Medical-grade oxygen cylinders are used extensively for this purpose, ensuring adequate oxygen supply during critical care and therapeutic interventions.
 

— Food Packaging:
In Modified Atmosphere Packaging (MAP) technology, oxygen helps preserve the color and freshness of meat products by preventing anaerobic conditions.

— Transportation and Preservation:
Oxygen is injected into liquid plastic bags containing seafood to maintain freshness during long-distance transport. It is also used in aquaculture to enhance oxygen levels in fish tanks, promoting healthier aquatic environments.

— Industrial Equipment:
Oxygen is crucial for various industrial applications, including metal welding and cutting processes where it combines with gases like acetylene to produce high-temperature flames. It is also utilized in laser and plasma cutting machines, enhancing their efficiency and precision.

Oxygen is versatility and essential role across industries make it a fundamental component in modern industrial and medical practices.
