Abstract
The invention relates to a method of separating oxygen from an oxygen comprising gas, the method comprising the steps of: performing at least a first and a second period of oxygen separation, the first and the second period of oxygen separation each comprising the steps of guiding an oxygen comprising gas to the primary side of an oxygen separation device (12, 14), the oxygen separation device (12, 14) comprising an oxygen separation sorbent (16, 18), and generating a flow of oxygen enriched gas out of the oxygen separation device (12, 14) by creating a pressure difference between the primary side and the secondary side of the oxygen separation device (12, 14), and performing a cooling period between the first and the second period of oxygen separation, wherein the cooling period comprises the steps of guiding a flushing sorbate through the oxygen separation device (12, 14), the flushing sorbate having an adsorption energy e1 with respect to the oxygen separation sorbent (16, 18), and guiding a cooling sorbate through the oxygen separation device (12, 14), the cooling sorbate having an adsorption energy e2 with respect to the oxygen separation sorbent (16, 18), wherein the adsorpti…
