Abstract
The invention relates to a method of separating oxygen from an oxygen containing gas, said method comprising the steps of: compressing and heating the oxygen containing gas in a plasma pump (16), guiding the heated and compressed oxygen containing gas to the primary side of a dense inorganic membrane (58), thereby heating the inorganic membrane by the oxygen containing gas to a temperature at which it is permeable for oxygen, and creating a pressure difference between the primary side and a secondary side of the inorganic membrane (58), wherein an oxygen flow through the inorganic membrane (58) is created, thereby separating the oxygen from the oxygen containing gas.
