Abstract

L'invention concerne un équipement de revaporisation de GNL fluide qui comprend un réservoir de stockage de GNL (10) et un dispositif de revaporisation de GNL (20), ainsi qu'un groupe électrogène pouvant produire d'une part de l'énergie, d'autre part du gaz à travers le dispositif de revaporisation (20). De ce fait, comme un générateur à turbine à gaz, qui est un groupe électrogène destiné à produire de l'énergie, est en outre inclus dans l'équipement de revaporisation pour revaporiser le GNL, il est en particulier possible de produire du gaz et de l'électricité en même temps. De même, puisqu'il est possible d'alimenter le générateur à turbine à gaz avec un gaz produit par l'équipement de revaporisation, un compresseur de gaz de traitement est exclu du générateur à turbine à gaz, ce qui permet de réduire le coût d'installation du générateur à turbine à gaz. De plus, après production de vapeur au moyen du gaz d'échappement émis par le générateur à turbine à gaz, le gaz produit peut être utilisé comme énergie d'alimentation à la fois pour le dispositif de revaporisation de GNL et pour un générateur à turbine à vapeur qui est ajouté pour générer de l'électricité. Il est ainsi possible de réduire au minimum l'énergie requise pour alimenter tout l'équipement grâce à la récupération de chaleur, ce qui permet de réduire les coûts et d'empêcher la pollution marine par l'utilisation de la chaleur résiduelle.
