Abstract

Le procédé permet la liquéfaction d'un gaz naturel sec comportant de l'eau et des hydrocarbures lourds comportant plus de cinq atomes de carbone. On effectue les étapes suivantes : a) on fait passer le gaz naturel sec à travers un solide adsorbant l'eau de manière à obtenir un gaz naturel appauvri en eau et un solide adsorbant chargé en eau; b) on fait passer le gaz naturel appauvri en eau à travers un solide adsorbant les hydrocarbures lourds comportant au moins cinq atomes de carbone de manière à obtenir un gaz naturel appauvri en hydrocarbures lourds et un solide adsorbant chargé en hydrocarbures lourds; c) on liquéfie le gaz naturel appauvri en hydrocarbures lourds à une pression supérieure à 40 bars absolu de manière à obtenir un gaz naturel liquide sous pression; d) on détend le gaz naturel liquide sous pression obtenu à l'étape c) jusqu'à la pression atmosphérique de manière à obtenir un gaz naturel liquide et une fraction gazeuse.
