| titleOfInvention | How to collect krypton and / or xenon using cryogenic air decomposition |
| abstract | The present invention is used to harvest krypton and / or xenon using low temperature air decomposition. The pressurized and washed feed gases 1, 1A, 1B, 29 are introduced into a rectifying system for nitrogen-oxygen separation comprising at least one high pressure column 2 and a low pressure column 3. At the first point of the low pressure column 3, the high oxygen content 42 is discharged. At least one first portion 43 of the high oxygen content 42 is passed back to a second point of the low pressure column, with a mass exchange section between the first and second points of the low pressure column. 44 is disposed. Another liquid 35 is discharged from the third point of the low pressure column 3, which is arranged at or below the height of the second point, and enters into the evaporation chamber of the first condensation-evaporator 4, where Partially evaporated. Fraction 138 containing krypton and xenon is withdrawn from the evaporation chamber of the first condensation-evaporator and introduced into the evaporation chamber of the second condensation-evaporator 27. Krypton-xenon concentrate 125 is withdrawn from the second condensation-evaporator 27. |
