Abstract
Abstract Apparatus for the continuous purification of gases contaminated with tritium by catalytic burning of tritium enriched hydrogen in a catalytic furnace and subsequent absorption of the tritium containing oxidation product. The apparatus has at least two gas storage containers which can be filled selectively by operating appropriately arranged valves, at least one catalytic furnace and at least one absorption plant for the oxidation product formed by way of which the gas storage container can be emptied selectively by appropriately arranged valves.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
267 words
Apparatus for the continuous purification of gases contaminated with tritium by the catalytic burning of tritium enriched hydrogen in a catalytic furnace, said apparatus comprising a source of tritium contaminated gas, at least first and second gas storage containers, at least one catalytic furnace for burning tritium from tritium contaminated gas and hydrogen to form water, a pump in operative communication with each of said gas storage containers and said catalytic furnace, first conduit means for operatively connecting said source to said first and second storage containers, second conduit means for connecting said storage containers to each other, third conduit means for connecting said second conduit means to said catalytic furnace, said pump being disposed in said third conduit means, means for absorbing the fluid water formed in said catalytic furnace, said means including at least one absorption unit, fourth conduit means connecting said absorption unit with said furnace, first valve means disposed in said first conduit means for permitting gas contaminated with tritium to pass from said source of contaminated gas to one of said storage containers, while selectively preventing tritium contaminated gas from entering the other of said storage containers, and second valve means located within said second conduit means for selectively permitting gas to pass from said first storage container to said catalytic furnace while selectively preventing the gas from passing from said second storage container to said catalytic furnace and for reversing the process whereby gas is prevented from passing from said first storage container to said catalytic furnace and gas is permitted to pass from said second storage container to said furnace.
Claim 2
Dependent Claim
267 words
Apparatus for the continuous purification of gases contaminated with tritium by the catalytic burning of tritium enriched hydrogen in a catalytic furnace, said apparatus comprising a source of tritium contaminated gas, at least first and second gas storage containers, at least one catalytic furnace for burning tritium from tritium contaminated gas and hydrogen to form water, a pump in operative communication with each of said gas storage containers and said catalytic furnace, first conduit means for operatively connecting said source to said first and second storage containers, second conduit means for connecting said storage containers to each other, third conduit means for connecting said second conduit means to said catalytic furnace, said pump being disposed in said third conduit means, means for absorbing the fluid water formed in said catalytic furnace, said means including at least one absorption unit, fourth conduit means connecting said absorption unit with said furnace, first valve means disposed in said first conduit means for permitting gas contaminated with tritium to pass from said source of contaminated gas to one of said storage containers, while selectively preventing tritium contaminated gas from entering the other of said storage containers, and second valve means located within said second conduit means for selectively permitting gas to pass from said first storage container to said catalytic furnace while selectively preventing the gas from passing from said second storage container to said catalytic furnace and for reversing the process whereby gas is prevented from passing from said first storage container to said catalytic furnace and gas is permitted to pass from said second storage container to said furnace.
Claim 3
Dependent Claim
119 words
Apparatus as recited in claim 1 further comprising fifth conduit means for connecting said absorption unit back to said first and said second storage containers for either emptying the storage tanks or for recycling the treated gas for further purification, and third valve means disposed in said fifth conduit means for selectively permitting gas to pass from said absorption unit back to said first storage container, while selectively preventing gas from passing from said absorption unit back to said second storage container, and for reversing the process whereby gas is prevented from passing from said absorption unit back to said first storage container while it is permitted to pass from said absorption unit back to said second storage container.
Claim 4
Dependent Claim
19 words
Apparatus as recited in claim 1, wherein said absorption unit includes a solid absorbent material which will absorb water.
Claim 5
Dependent Claim
61 words
Apparatus as recited in claim 1, wherein said absorbing means comprises a plurality of absorption units, and wherein said apparatus further comprises fourth valve means disposed in said fourth conduit means for selectively permitting effluent from said catalytic furnace to at least one absorption unit while selectively simultaneously preventing effluent from said furnace from passing to another of said absorption units.
