Abstract
L'invention concerne un procédé et un appareil pour séparer l'azote contenu dans une charge d'alimentation gazeuse comprenant un mélange d'hydrocarbures et d'azote gazeux. Le procédé selon l'invention comprend les étapes qui consistent : (i) à refroidir et condenser au moins partiellement la charge d'alimentation gazeuse; (ii) à introduire la charge d'alimentation refroidie et au moins partiellement condensée au cours de l'étape (i) dans une première tour de fractionnement pour produire un courant de vapeur de tête à teneur élevée en azote et un condensat à teneur réduite en azote qui subit un deuxième fractionnement lequel consiste notamment à réaliser une nouvelle ébullition à une pression inférieure à celle régnant dans la première tour de fractionnement; (iii) à condenser au moins partiellement le courant de vapeur de tête, et à procéder à une séparation pour obtenir un courant liquide lequel est utilisé pour obtenir un reflux dans la première tour de fractionnement, et un courant de vapeur séparé qui est condensé pour obtenir un reflux dans la deuxième tour de fractionnement; et (iv) à procéder au sous-refroidissement du condensat du premier fractionnement et à diviser le produit sous-refroidi résultant en au moins deux courants : un premier courant qui subit une expansion et qui est introduit dans la deuxième tour de fractionnement, et un deuxième courant qui subit une expansion, est réchauffé par échange thermique avec le courant de vapeur séparé issu de l'étape (ii) avant d'être introduit dans la deuxième tour de fractionnement; (v) à supprimer un courant de produits hydrocarbures à faible teneur en azote se trouvant dans la deuxième tour de fractionnement; et (iv) à supprimer un courant riche en azote se trouvant dans la deuxième tour de fractionnement.
