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.

A pressure swing sorption process for removing at least a portion of a substance from a gas containing the substance, the method comprising the steps of: simultaneously directing the gas through a sorbent bed contained in a first sorbing chamber to an outlet, directing a portion of the outlet gas through a sorbent bed contained in a second sorbing chamber to an exhaust, and providing energy from an energy source external to the sorbent beds of the first and second sorbing chambers to a heater near a sorption inlet region of the sorbent bed contained in the second sorbing chamber to heat the sorption inlet region as the outlet gas flows therethrough and cycling between the first and second sorbing chambers according to a NEMA cycle length of less than about 5 minutes wherein one sorbent bed sorbs at least a portion of the substance from the gas and is heated by the heat of adsorption and the other sorbent bed is regenerated using both the energy supplied by the heater and the heat of adsorption. A pressure swing sorption system for removing at least a portion of a substance from a gas containing the substance, the sorption system comprising: first and second sorbing chambers, each sorbing chamber including first and second openings defining a gas flow path between the first and second openings, 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; an energy source external to the sorbent beds of the first and second sorbing chambers; means for connecting the energy source to the heaters of the first and second sorbing chambers; an intake, an outlet, and an exhaust; a valve arrangement interconnecting the intake, the exhaust, and the first openings of the first and second sorbing chambers and interconnecting the outlet and the second openings of the first and second sorbing chambers; and a controller coupled to the valve arrangement and the connecting means for simultaneously directing gas through one sorbing chamber of the outlet, directing a portion of the outlet gas through the other sorbing chamber to the exhaust, and providing energy from the external energy source to the heater of said other sorbing chamber to heat the sorption inlet region of said other sorbing chamber as the outlet gas flows through the sorption inlet region, wherein the controller is adapted to cycle between the first and second sorbing chambers according to a NEMA cycle length of less than about 5 minutes and wherein one sorbent bed sorbs at least a portion of the substance from the gas and is heated by the heat of adsorption and the other sorbent bed is regenerated using both the energy supplied by the heater and the heat of adsorption.
