Abstract
Described is a method of conditioning a gas stream comprising passing the gas stream into a vessel 10 which contains a rotating enclosure 12 and which contains an apparatus 18 to rotate the enclosure, which enclosure is pressure sealed from the surrounding atmosphere and which is divided into a plurality of modulating zones 14, 16; treating the gas to modify its properties within the enclosures due to the presence of modulating materials 68 within the zones in the enclosure; and passing the modified gas to an outlet 24, 25 of the vessel. Also described is an apparatus for conditioning a plurality of gas streams.
Claims10
A method of conditioning a gas stream by decreasing humidity therein comprising passing the gas stream into a vessel which vessel contains a rotating enclosure and which contains a motor to rotate the enclosure, which enclosure is pressure sealed from the surrounding atmosphere and which is divided into a plurality of modulating zones;
- treating the gas to modify its properties within the enclosures due to the presence of modulating materials within the zones in the enclosure which materials decrease humidity in the stream;
- and passing the modified gas to an outlet of the vessel.
An apparatus for conditioning a plurality of gas streams comprising a vessel which contains an enclosure capable of rotating therein, which enclosure is pressure sealed from the surrounding atmosphere and which is divided into a plurality of modulating zones;
- the zones having the ability to modify the properties of the gas streams coming in contact with the zones due to the presence of modulating materials therein which material decreases humidity in the stream;
- a motor within the vessel capable of rotating the enclosure within the vessel to facilitate the contacting of the gas streams within the zones;
- and
- an inlet to the vessel for the gas streams and an outlet from the vessel to pass the modulated gas streams from the vessel,
- whereby the gas streams pass through the inlet to the vessel and then to the enclosure and are modified in the zones as the enclosure is rotated and exits from the enclosure zones in a modified form and then exit from the vessel whereby the gas stream that exits the apparatus has a decreased humidity.
A method for conditioning a gas stream for a fuel cell apparatus by decreasing humidity therein comprising passing the gas stream into a vessel which vessel contains a rotating enclosure and which contains a motor to rotate the enclosure, which enclosure is pressure sealed from the surrounding atmosphere and which is divided into a plurality of modulating zones;
- treating the gas to modify its properties within the enclosures due to the presence of modulating materials within the zones in the enclosure which materials decrease humidity in the stream;
- and passing the modified gas to an outlet of the vessel to be utilized in the fuel cell apparatus.
An apparatus for conditioning a plurality of gas streams present in a fuel cell apparatus by decreasing humidity therein comprising an inlet for passing the gas stream into a vessel which vessel contains a rotating enclosure and which contains a motor to rotate the enclosure, which enclosure is pressure sealed from the surrounding atmosphere and which is divided into a plurality of modulating zones for treating the gas to modify its properties within the enclosure due to the presence of modulating materials within the zones in the enclosure which materials decrease humidity in the stream;
- and an outlet for passing the modified gas from the vessel to be utilized in the fuel cell apparatus.
