| titleOfInvention | Rare gas recovery method |
| abstract | PROBLEM TO BE SOLVED: To separate rare gas composed of krypton and xenon at a high recovery rate and to suppress the concentration of hydrocarbons in an air liquefaction separator. SOLUTION: The liquefied oxygen phase 4 in the vicinity of the reboiler condenser 2 of the air liquefaction separator provided with a tray 1c for improving the separation efficiency of the rare gas in the upper tower lower part of the air liquefaction separator 1 and above the reboiler condenser 2 In recovering the rare gas from the liquefied oxygen containing the rare gas extracted from the liquefied oxygen, the liquefied oxygen is introduced into the first enrichment tower 6, and the concentrated liquefied oxygen in which the rare gas and the hydrocarbon are concentrated from the bottom of the tower. Removing oxygen gas 8 from the top of the column, and removing the concentrated liquefied oxygen 9 via the dehydrocarbonation device 14 into the second concentration column 1 1 and oxygen gas from the top, rare gas liquid 1 from the bottom 3 and a step of charging at least a part of the oxygen gas from the top of the first concentration tower as the circulating liquefied oxygen gas 10 into the liquefied oxygen phase 4 of the air liquefaction / separation apparatus 1. Collection method. |
