摘要： A storage vessel comprises a condenser for condensing boil-off vapor by direct heat exchange with cryogenic liquid feed to the vessel. The condenser comprises a packed arrangement of vapor-liquid contact packing that comprises a top end portion and a bottom end portion. At least said top end portion is open to the vapor space to allow entry of boil-off vapor into the arrangement. The bottom end portion is in fluid flow communication with the lower portion of the storage vessel. One advantage of the invention is that the condenser is open to the vapor space of the storage vessel thereby allowing boil-off vapor to be drawn into the condenser by the condensation action of the vapor.

摘要： Krypton and/or xenon is separated crudely from a mixture comprising oxygen and at least one rare gas selected from the group consisting of krypton and xenon in a process comprising feeding said mixture or a mixture derived therefrom to a rare gas recovery system and separating said mixture feed in said rare gas recovery system into rare gas-lean gaseous oxygen (“GOX”) and rare gas-enriched product. The process is characterized in that at least about 50 mol % of said mixture is fed to the rare gas recovery system in the gaseous phase provided that, when said mixture feed is separated by selective adsorption, the concentration of xenon in the mixture feed is no greater than 50 times the concentration of xenon in air. One advantage of a preferred embodiment of the present invention is that it can easily be retrofitted to existing pumped LOX cycle ASUs.

摘要： Liquid oxygen (“LOX”) product and a krypton- and xenon-enriched liquid product is produced from the cryogenic separation of air using a cryogenic distillation system. The process comprises separating feed air in the main distillation system into nitrogen-rich overhead vapor and said krypton- and xenon-enriched liquid product. At least a portion of said krypton- and xenon-enriched liquid product is removed from the main distillation system for further distillation, to produce at least one krypton- and/or xenon-rich product. Xenon-lean liquid is fed to the first additional distillation column and separated into oxygen-rich overhead vapor and said LOX product having a concentration of xenon less than that in said feed air. The xenon-lean liquid is usually also lean in krypton.
