Beschreibung
Zusammenfassung:	A gas separation device is disclosed. In particular, seal assemblies and adsorbent element constructions for a gas separation device such as a pressure swing adsorption device are disclosed. The seal assembly can be part of a rotary valve and can include a seal backer and a floating seal positioned within a bore in the seal backer. The floating seal is configured to press towards and seal against an adjacent rotor. Valve action is provided as apertures in the floating seal and rotor are brought into and then out of alignment as a result of relative rotation therebetween. The seal assembly can include two types of gas chambers to apply balanced sealing pressures over the sealing surface of the valve, one type configured to receive pressurized process gas from within the device and the other configured to receive gas from an independently controlled pressurized gas source. The adsorber elements in the device may comprise improved spacer cross support structures at the ends of wound laminate adsorbent structures.
