Abstract
The invention relates to an oxygen separation device (12, 14), comprising a gas inlet (29, 31) at a primary side for guiding a flow of oxygen comprising gas into the oxygen separation device (12, 14) and having a gas outlet (33, 35) at a secondary side for guiding a flow of oxygen enriched gas out of the oxygen separation device (12, 14), at least one oxygen separation area (20, 22) with an oxygen separation sorbent (16, 18) being capable of separating oxygen from an oxygen comprising gas by sorbing at least one component of the oxygen comprising gas apart from oxygen and being contaminatable by a contaminant, and a decontamination area (21, 23) with a decontamination material (17, 19) for decontaminating the oxygen comprising gas from at least one contaminant, wherein the oxygen separation area (20, 22) and the decontamination area (21, 23) are fluidly connected by a spacer (76, 78) comprising at least one diffusion reducing channel (80, 82), wherein the spacer (76, 78) has a value of diffusion reduction rR of rR>1. Such an oxygen separation device (12, 14) allows (10) provides significant advantages with respect to maintenance. The invention further relates to an oxygen separator…
