The adsorption oxygen plants produce 5 to 5,000 normal cubic meters per hour of oxygen with a purity of 93-95%. These systems, designated for indoor operation, are set to effectively produce gaseous oxygen from atmospheric air. An unquestionable advantage of adsorption-based oxygen plants is the low cost of oxygen produced in the cases where ...
A cryogenic gas plant is an industrial facility that creates molecular oxygen, molecular nitrogen, argon, krypton, helium, and xenon at relatively high purity. [1] As air is made up of nitrogen, the most common gas in the atmosphere, at 78%, with oxygen at 19%, and argon at 1%, with trace gasses making up the rest, cryogenic gas plants separate air inside a distillation column at cryogenic ...
Mars Oxygen ISRU Experiment. The Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) [1] was a technology demonstration on the NASA Mars 2020 rover Perseverance investigating the production of oxygen on Mars. [2] On April 20, 2021, MOXIE produced oxygen from carbon dioxide in the Martian atmosphere by using solid oxide electrolysis.
Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz-Donawitz steelmaking or the oxygen converter process, [1] is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel.
Major costs are instead CO 2 compression, needed in all CO 2 capture technologies, and oxygen production. Molecular oxygen production may also be needed in certain CLC configuration for polishing the product gas from the fuel reactor. In all the added costs were estimated to 20 €/tonne of CO 2 whereas the energy penalty was 4%. [20]
for oxygen: up to 1500 Nm 3 /h with a purity between 88% and 93%. [3] In the frame of carbon capture and storage (CCS), research is also currently underway to capture CO 2 in large quantities from coal-fired power plants prior to geosequestration, in order to reduce greenhouse gas production from these plants.

Air separation. An air separation plant separates atmospheric air into its primary components, typically nitrogen and oxygen, and sometimes also argon and other rare inert gases. The most common method for air separation is fractional distillation. Cryogenic air separation units (ASUs) are built to provide nitrogen or oxygen and often co ...
Oxy-fuel combustion also reduces CO 2 release at the glass plant location, although this may be offset by CO 2 production due to electric power generation which is necessary to produce oxygen for the combustion process. Oxy-fuel combustion may also be cost effective in the incineration of low BTU value hazardous waste fuels.
