Abstract

L'invention concerne un procédé et un appareil (1) permettant de rejeter l'azote d'un flux d'hydrocarbure (10) pour produire un flux de gaz combustible (510). Un flux d'hydrocarbure (10) est au moins partiellement liquéfié et, par la suite, détendu. Le flux d'hydrocarbure détendu (110) est fractionné dans une colonne de fractionnement (150) pour produire un flux d'hydrocarbure riche en azote (160) et un flux d'hydrocarbure pauvre en azote (170). Le flux d'hydrocarbure riche en azote (160) est partiellement condensé dans un condenseur (200) par refroidissement contre un réfrigérant que l'on fait circuler dans un premier circuit réfrigérant spécialisé (800), et qui est séparé en phase pour produire un flux de rejet d'azote (260) et un flux de reflux pauvre en azote (270) que l'on retourne vers la colonne de fractionnement (150). Le flux d'hydrocarbure pauvre en azote (170) est partiellement vaporisé et séparé en phase pour produire un flux de vapeur que l'on retourne à la colonne de fractionnement (150) et un flux d'hydrocarbure pauvre en azote (370) que l'on soumet à un sous-refroidissement. Le flux de gaz combustible (510) est généré à partir du flux d'hydrocarbure pauvre en azote (410).
