Abstract

Ce procédé comprend les étapes qui consistent à adoucir et sécher le gaz naturel brut à une pression supérieure à 55,4 atmosphères, à dépressuriser le gaz à une pression inférieure à 14,6 atmosphères dans des moyens de récupération d'énergie délivrant de la puissance mécanique, à épurer ou laver le gaz dépressurisé résultant avec un courant pauvre d'hydrocarbures pour retirer les hydrocarbures ayant deux ou plus de deux atomes de carbone par molécule, à faire subir au courant de gaz restant une seconde opération de séchage pour fournir un courant de gaz adapté à la liquéfaction, à extraire les hydrocarbures en C1 -C 3 du courant riche d'hydrocarbures formé par lavage du courant de gaz dépressurisé, et à utiliser une partie du liquide résultant comme courant pauvre d'hydrocarbures.
