Oxygen (O2) is a colorless, odorless, and tasteless gas that makes up about 21% of the Earth’s atmosphere. It is essential for life, as it is used by all living things to produce energy. Oxygen is also a major component of many industrial processes.

Oxygen gas is used in a wide range of applications, including:

• Medical: Oxygen is used to treat patients with respiratory problems, such as asthma and pneumonia. It is also used in surgery and other medical procedures.
• Industrial: Oxygen is used in a variety of industrial processes, such as steelmaking, glassmaking, and chemical production.
• Food and beverage: Oxygen is used in the food and beverage industry to preserve food, carbonate drinks, and produce oxygenated water.
• Environmental: Oxygen is used in wastewater treatment to improve the efficiency of the treatment process. It is also used in aquaculture to increase the oxygen content of the water, which can improve the health and growth of fish and other aquatic life.

Oxygen gas is used in a wide range of industries, including:

• Medical: hospitals, clinics, emergency medical services
• Industrial: steel mills, glass factories, chemical plants, food processing plants, wastewater treatment plants, aquaculture facilities

Oxygen gas is available in a variety of purity grades, depending on the application. The most common purity grades are:

• Medical grade: 99.5% purity
• Industrial grade: 99% purity
• Ultra high purity (UHP): 99.999% purity

UHP oxygen is required for some applications, such as semiconductor manufacturing and medical devices.

Oxygen gas is typically supplied in cylinders, bulk tanks, and liquid tankers. The most appropriate supply option depends on the volume of oxygen required and the application.

• Cylinders: Cylinders are the most common way to supply oxygen for small-volume applications. They are available in a variety of sizes and purity grades.
• Bulk tanks: Bulk tanks are a good option for medium- to large-volume applications. They can be installed on-site and refilled by a gas supplier.
• Liquid tankers: Liquid tankers are used to supply oxygen for very large-volume applications, such as steelmaking and chemical production.
