Abstract

On propose un procédé dextraction sélective de liquides de gaz naturel à partir de gaz naturel « riche ». Le procédé comprend les étapes qui consistent à déclencher un échange thermique entre un flux de gaz naturel riche et un fluide frigorigène pour abaisser une température du flux de gaz naturel riche. Léchange thermique est régulé pour abaisser la température du flux de gaz naturel riche au point de rosée dhydrocarbures sélectionnés pour condenser au moins un hydrocarbure liquide sélectionné contenu dans le flux de gaz naturel riche.
