ABSTRACT:
A system for purifying a gas provided with an apparatus comprising a main container defining a substantially closed chamber, an intake fitting having an intake projecting from the chamber and having inside the chamber a filter element, an outlet fitting having an outlet projecting from the chamber offset from the intake and having inside the chamber a filter element offset from the filter element of the intake fitting, and means defining in the chamber an internally sealed well between the filters. A baffle is provided in the chamber between the filters so that gas passing between the filters is deflected by the baffle. A heater is provided in the well. An outer container surrounds the main container and defines a space therearound. This space is insulated, either by being filled with an insulating material or by being evacuated. An active material generally fills the chamber around the filters and well so that a gas passing through the chamber from the intake filter to the outlet filter contacts the active material. Optionally the device may also have partitions defining in the chamber a second internally sealed well or a thermocouple. This thermocouple permits one to monitor the temperature of the active material bed.
