ABSTRACT:
A pressure swing sorption system comprises first and second sorbing chambers each including first and second openings defining a gas flow path between them, a sorbent bed disposed in the gas flow path and having a sorption inlet region near the first opening, and a heater positioned near the sorption inlet region of the sorbent bed. A valve arrangement interconnects an intake, an exhaust, and the first openings of the first and second sorbing chambers and also interconnects an outlet and the second openings of the first and second sorbing chambers. A connecting apparatus connects an energy source external to the first and second sorbing chambers to the heaters of the first and second sorbing chambers. A controller coupled to the valve arrangement and the connecting apparatus simultaneously directs gas from the first sorbing chamber to the outlet and directs a portion of the outlet gas through the second sorbing chamber to the exhaust. The controller also provides energy from the energy source to the heater of the second sorbing chamber to heat the sorption inlet region of the second sorbing chamber as the outlet gas flows through the sorption inlet region.
