Abstract (en)
[origin: EP0694746A1] A process and installation are claimed for the production of a gas under pressure, at a variable flow rate, particularly for the distillation of air to produce oxygen and nitrogen streams. Air is distilled in a distillation column (7) after cooling by heat exchange (6) with distillation products. Liquid oxygen is withdrawn from the column (16 and 17) and stored (11) at near atmospheric pressure, then used at a variable rate (12). Liquified air is stored (13) at a pressure higher than that in the distillation column before use. It is fed to the column as needed via a pressure reducing valve (25). <IMAGE>
