Oxygen is essential for many industrial applications. In most applications, oxygen purity is required to be above 95%, and applications for oxygen include, but are not limited to:

Metallurgy: Modern steelmaking relies heavily on the use of oxygen to enrich air and increase combustion temperatures in furnaces, as well as to replace coke with other combustible materials. Used with fuel gases in gas welding and gas cutting, oxygen must be of high quality to ensure a high cutting speed and a clean cut. Large quantities of oxygen are also used to make other metals, such as copper, lead, and zinc.

Welding process: In gas welding and cutting operations, the oxygen used as an oxidizer must be of high quality to ensure high-speed and clean cutting.

Aquaculture: High purity oxygen is crucial to modern day fish farming. Correctly dosed pure oxygen is essential to livestock yields, growth potential and their overall health.

Food & Beverage: The concentration of ambient air into oxygen and ozone is key to the environmental and sustainable production in the food & beverage industry, including sanitisation of process equipment, food storage, and water bottling.

Chemical industry: Manufacturing pharmaceutical, fuel, explosives and other chemical products, oxygen blowing method to produce yellow phosphorus, oxygen injection bad coal and so on.

Electronic industry: Oxygen is not only used as a combustion aid gas, but also an indispensable oxidizing gas for manufacturing semiconductor integrated circuits. High purity oxygen is also an important gas raw material for manufacturing optical fibers.

Glass and Ceramics Production: Oxygen is used instead of air to optimise combustion and elevate flame temperatures in glass melting tanks. This results in better control of heating patterns, lower fuel consumption, and reduction in particulate and NOx emissions.

Pulp & Paper: In the manufacture of high-quality bleached pulp, oxygen is used in the bleaching process. New processes using oxygen, rather than chlorine, reduce water pollution and lowers costs.

Wastewater Treatment: In industrial and municipal wastewater treatment plants, oxygen is injected during the treatment process. Also known as the activated sludge process, pumping oxygen into the wastewater tank encourages the growth of bacteria and speeds up the bio-degradation process which breaks down organic matter.

Respiratory oxygen: The use of oxygen to rescue choking patients, critically ill patients. Oxygen can be used as a breathing gas to supply mountaineers, divers, geological explorers, border guards and other special groups.
