Abstract[English]
The invention relates to a method for producing a fuel for driving a gas turbine (4), including the steps of: - pressurizing liquid ammonia, - the pressurized ammonia is fed by a feeding line (6) into an ammonia cracking device (10) and partially cracked using exhaust gas heat from the gas turbine (4), - a mixture of hydrogen, nitrogen and uncracked ammonia is taken out of the ammonia cracking device (10) to a cooling unit (14) and cooled down to ambient temperatures, - in a gas-liquid-separator (16), the gaseous mixture of hydrogen, nitrogen and uncracked ammonia is separated from the uncracked, liquid ammonia by means of centrifugal and/or gravitational forces, - the gaseous mixture of hydrogen, nitrogen and uncracked ammonia is fed to at least one burner (22) of the gas turbine (4), - the uncracked, liquid ammonia from the gas-liquid- separator (16) is mixed with the pressurized ammonia in the feeding line (6). In this method the exhaust heat of the gas turbine is advantageously used in the cracking process.[French]
L'invention concerne un procédé de production d'un carburant destiné à l'entraînement d'une turbine à gaz (4). Ledit procédé comprend les étapes consistant à : pressuriser l'ammoniac liquide ; alimenter l'ammoniac sous pression au moyen d'une ligne d'alimentation (6) dans un dispositif de craquage d'ammoniac (10) et le craquer partiellement à l'aide de la chaleur des gaz d'échappement provenant de la turbine à gaz (4) ; amener un mélange d'hydrogène, d'azote et d'ammoniac non craqué du dispositif de craquage d'ammoniac (10) vers une unité de refroidissement (14) et le refroidir à des températures ambiantes ; dans un séparateur gaz-liquide (16), séparer le mélange gazeux d'hydrogène, d'azote et d'ammoniac non craqué de l'ammoniac liquide non craqué au moyen de forces centrifuges et/ou gravitationnelles ; introduire le mélange gazeux d'hydrogène, d'azote et d'ammoniac non craqué dans au moins un brûleur (22) de la turbine à gaz (4) ; et mélanger l'ammoniac liquide non craqué provenant du séparateur gaz-liquide (16) avec l'ammoniac sous pression dans la ligne d'alimentation (6). Dans ledit procédé, la chaleur d'échappement de la turbine à gaz est avantageusement utilisée dans le procédé de craquage.
