Abstract

Il est décrit une méthode visant à produire du gaz naturel liquéfié (GNL) et du gaz naturel comprimé à froid (GNCF) dans des usines de chevauchement. Par opposition à la pratique actuelle dans les usines de chevauchement, un écoulement dun flux de gaz naturel à haute pression, pré-traité, pré-refroidi est ajouté, dans le but dalimenter une nouvelle section de production de GNL ou de GNCF. Cet écoulement est en outre refroidi dans un échangeur de chaleur par une fraction de vapeur à contre-courant du gaz détendu avant dentrer dans un appareil dexpansion. Le gaz refroidi est détendu dans un séparateur. La fraction de vapeur froide provenant du séparateur est acheminée vers la colonne de fractionnement de lusine de chevauchement, où elle est détendue. Le GNL produit est acheminé vers le stockage.
