Abstract
Technique et appareil associé pour l'extraction de benzène, d'autres aromatiques et/ou d'autres composants d'hydrocarbures lourds d'un courant gazeux à base de méthane, par condensation et stripage. Il est souhaitable d'extraire le benzène et d'autres aromatiques pour éviter d'encrasser et d'obstruer le matériel de traitement. Il est également souhaitable de récupérer les autres composants des hydrocarbures lourds en raison de leur valeur. Le courant d'alimentation refroidi (118) passe dans une colonne (60) et est séparé en courant de vapeur riche en méthane (120) et en liquide contenant du benzène, des aromatiques et des hydrocarbures lourds (114). Le liquide (114) passe ensuite dans un échangeur de chaleur (62) où il est refroidi. Le gaz sec et chaud (108) est refroidi dans l'échangeur de chaleur (62) et passe dans la colonne (60) sous forme de gaz de stripage (109).
