Okesen o se tasi o vaega o le ea ma e leai se lanu ma leai se aoga. Okesen o lo o faafitiina nai lo le ea. O le auala e maua ai le okesene i luga o se fua tele o le vaega o le ea suavai ea. Muamua, o le ea o loʻo faʻamalosia, faʻateleina ona faʻaʻaisa lea i le ea i le ea. Talu ai o le le mautonu o meaʻai ma nitrogen ua maualalo le faʻaputuga pito i lalo ifo o le okesene, o le a le mea e totoe pe a uma le faʻavaʻa o le okesene o le okesene. All oxidation reactions and combustion processes require oxygen. For example, in the steelmaking process, impurities such as sulfur and phosphorus are removed. The temperature of the mixture of oxygen and acetylene is as high as 3500 °C, which is used for welding and cutting of steel. Oxygen is required for glass making, cement production, mineral roasting and hydrocarbon processing. Liquid oxygen is also used as rocket fuel and is cheaper than other fuels. People who work in hypoxic or oxygen-deficient environments, such as divers and astronauts, are vital to sustaining life. Peitaʻi, o le malosi o le okesene, pei o le hot ma h2o2, o le leaga o le paʻu ma mata e mafua mai i le ultraviolet ras e fesoʻotaʻi ma le faʻaleagaina o le tino.

Most commercial oxygen is made from air separation, where the air is liquefied and purified by distillation. Low temperature total distillation can also be used. E laititi le tele o le okesene o le okesene ua filifilia o mea mata, ma le maualuga-amio okesene ma le mama o le sili atu 99.99% e mafai ona gaosia pe a uma ona gaosia. Other purification methods include pressure swing adsorption and membrane separation.
