Abstract
A device for the catalytic conversion of hydrogen in a containment of a reactor containing a gas mixture. The device includes a recombiner which is disposed in the containment and has a plurality of catalytically active catalyst elements, a first cooling unit which is disposed upstream of the recombiner and cools the gas mixture and a second cooling unit disposed downstream from and behind the recombiner. The device effectively eliminates hydrogen resulting from an accident in the containment, without flashback. The device also suppresses heating of the atmosphere in the containment.
Claims19
A device for the catalytic conversion of hydrogen in a containment of a reactor containing a gas mixture, said gas mixture ascending under the action of an updraft, comprising:
- a recombiner having an inlet and an outlet, said recombiner having a plurality of catalytically active catalyst elements,
- a first cooling unit for cooling the gas mixture, said first cooling unit being disposed adjacent to the inlet of the recombiner, and
- a second cooling unit being disposed adjacent to the outlet of the recombiner,
- said first cooling unit, said recombiner, and said second cooling unit being disposed in the containment of the reactor and being fastened to at least one wall of the containment,
- wherein the first cooling unit is disposed in direct contact with the ascending gas mixture, and
- wherein the second cooling unit comprises an outlet for discharging the gas mixture into the containment.
A method for the catalytic conversion of hydrogen in a containment of a reactor containing a gas mixture, said gas mixture ascending under the action of an updraft, comprising:
- (a) directing the ascending gas mixture directly into a first cooling unit for cooling the gas mixture before entering a recombiner, said recombiner having an inlet and an outlet, said recombiner having a plurality of catalytically active catalyst elements, said first cooling unit being disposed adjacent the inlet of the recombiner and being in direct contact with the gas mixture, whereby hydrogen is recombined with oxygen when in contact with the catalytically active catalyst elements of the recombiner, and
- (b) directing the gas mixture into a second cooling unit for cooling the gas mixture before discharging the gas mixture into the containment, said second cooling unit being disposed adjacent to the outlet of the recombiner,
- wherein said first cooling unit, said recombiner, and said second cooling unit are disposed in the containment of the reactor and are fastened to at least one wall of the containment.
