  • Patent number: 6637240
    Abstract: A process for producing a nitrogen-enriched vapor product from a supply of a nitrogen-rich liquid uses a purifying device and a distillation column having a distillation zone. The process includes the steps of: feeding at least a portion of the supply of the nitrogen-rich liquid to the distillation zone at a first location; feeding a stream of a gas containing nitrogen and at least one contaminant to the purifying device, wherein the gas is cooled by a cryogenic liquid whereby at least a portion of the at least one contaminant condenses, solidifies, or dissolves; eventually feeding at least a portion of the cool gas from the purifying device to the distillation zone at a second location below the first location; withdrawing a stream of the nitrogen-enriched vapor product from the distillation zone; and withdrawing a stream of an oxygen-enriched liquid from the distillation zone.
