Abstract | The invention is directed to a method of fueling gas turbines from natural gas reserves with relatively low methane concentrations. The invention uses such reserves to generate electric power. The invention permits the use of these reserves at significantly lower cost than by producing pipeline natural gas to fuel gas turbines to generate electric power. These reserves currently generally are used only after the removal of impurities to produce pipeline natural gas quality turbine fuel. The latter current technology is capital intensive, and at current natural gas prices, economically unattractive. The process of the invention can remove the impurities from the gas from the natural gas reserve necessary for protection of the environment, and leaves inert gasses in the fuel in an amount which will increase the output of a gas turbine for the generation of power by about 5 to about 20 %.
L'invention concerne un procédé permettant de ravitailler des turbines à gaz à partir de réserves de gaz naturel contenant des concentrations relativement faibles de méthane. L'invention utilise ces réserves pour générer de l'énergie électrique. L'invention permet l'utilisation de ces réserves à un coût sensiblement inférieure par rapport à la production de gaz naturel de pipeline pour ravitailler des turbines à gaz servant à générer de l'énergie électrique. Ces réserves sont généralement utilisées actuellement uniquement après que les impuretés ont été enlevées pour produire du combustible de turbine du type gaz naturel de pipeline. Les techniques les plus récentes requièrent de gros investissements, et aux prix du gaz naturel, elles sont inintéressantes du point de vue économique. Le procédé de l'invention permet de retirer les impuretés du gaz provenant de la réserve de gaz naturel, étape nécessaire pour la protection de l'environnement, et de laisser les gaz inertes dans le combustible dans une quantité permettant d'accroître de 5 à 20 % environ la puissance d'une turbine à gaz destinée à générer de l'énergie. |
