Separation method and apparatus for separating a gaseous mixture, for example, air, in a cryogenic rectification plant (1) in which a compressed stream (42) is divided into subsidiary streams (126, 128) that are extracted from a main heat exchanger (18) of the plant at higher and lower temperatures. The two streams are then combined and expanded in a turboexpander (36) to generate refrigeration for the plant. The flow rates of the two streams are adjusted to control inlet temperature of a turboexpander supplying plant refrigeration and to minimize potential deviation of the turboexpander exhaust from a saturated vapor state. Control of the expansion ratio can advantageously be applied to allow variable liquid production from the rectification plant.

L'invention concerne un procédé et un appareil de séparation pour séparer un mélange gazeux, par exemple de l'air, dans une installation de rectification cryogénique (1) dans laquelle un courant comprimé (42) est divisé en courants auxiliaires (126, 128) qui sont extraits de l'échangeur de chaleur principal (18) de l'installation à des températures supérieures et inférieures. Les deux courants sont ensuite combinés et détendus dans un turbodétendeur (36) pour réfrigérer l'installation. Les débits des deux courants sont ajustés pour réguler la température d'admission d'un turbodétendeur assurant la réfrigération de l'installation et pour réduire au minimum l'écart potentiel de l'échappement du turbodétendeur par rapport à un état de vapeur saturé. La régulation du rapport de détente peut permettre de varier avantageusement la production liquide de l'installation de rectification.
