OXYGEN SEPARATOR AND METHOD OF OXYGEN GENERATION Russian patent published in 2017 - IPC B01D53/47 A62B21/00 

FIELD: machine engineering.

SUBSTANCE: method for separating oxygen from an oxygen-containing gas comprises the steps of at least the first and second oxygen separation periods, wherein each first and second oxygen separation periods comprise the steps of guiding the oxygen-containing gas to the primary side of the oxygen separation unit (12, 14) containing the sorbent (16, 18) for separating oxygen, and generating an oxygen-enriched gas stream from the oxygen separation device (12, 14) by creating a pressure difference between the primary side and the secondary side of the device (12, 14) separation of oxygen. The method comprises a cooling step between the first and second oxygen separation periods, wherein the cooling period comprises the steps of adding the sorbate through the oxygen separation device (12, 14), the sorbate added having an adsorption energy e₁ with respect to the sorbent (16, 18) for separating oxygen, and directing the cooling sorbate through the oxygen separation unit (12, 14). The cooling sorbate has an adsorption energy e₂ with respect to the sorbent (16, 18) for separating oxygen. The adsorption energy e₂ is less than the adsorption energy e₁. The invention also provides an oxygen separator (10).

EFFECT: invention makes it possible to improve the separation of oxygen, especially at high temperatures.
