摘要： A process and a plant for removing the gaseous fluorocompounds or fluorosulphur compounds, such as CF4, C2F6, and SF6, present in a stream of xenon and/or krypton, by permeation via one or more membranes, such as polymer membranes. The xenon and/or krypton thus produced may then be further purified or separated by cryogenic distillation. Prior to the permeation step, the other impurities, particularly the hydrocarbons, may be removed by oxidative catalysis and subsequent adsorption of the carbon dioxides and of the water produced. The xenon, the krypton and the xenon/krypton mixtures free of gaseous fluorocompounds or fluorosulphur compounds and purified by such process can be used as plasma propulsion gas, especially for satellites, or as inter-pane insulation gas for a sealed unit, particularly for double-glazing windows.

摘要： Process and installation for the production of gaseous oxygen under pressure by cryogenic distillation of air in a double column (5) comprising a medium pressure column (6) and a low pressure column (7). Rich liquid from the medium pressure column is divided into first and second liquid fractions which are sent to different levels in the low pressure column (7). These different levels are both below the level of withdrawal of impure nitrogen from the low pressure column (7). A fluid enriched in argon is withdrawn from the low pressure column (7) and distilled in an argon column (16). Liquid enriched in oxygen is withdrawn from a lower portion of the low pressure column (7). The two fractions of rich liquid are cooled to different temperatures before being sent to the low pressure column (7). A portion of the supply air is blown into an intermediate level of the low pressure column (7) and the levels of injection of the rich liquid are not below this intermediate level.
