Title (EN) STAGED STEAM INJECTION SYSTEM
(FR) SYSTÈME D'INJECTION DE VAPEUR ÉTAGÉ
Abstract:
(EN) A staged steam injection system for a flare tip that can discharge waste gas into a combustion zone is provided. The staged steam injection system includes, for example, a first gas injection assembly and a second stage gas injection assembly. The first gas injection assembly is configured to inject steam at a high flow rate and a high pressure into the flare tip or the combustion zone. The second gas injection assembly is configured to inject a gas (for example, steam and/or a gas other than steam) at a low flow rate and a high pressure into the flare tip or the combustion zone. A flare tip including the staged steam injection system is also provided.
(FR) L'invention concerne un système d'injection de vapeur étagé pour un nez de torche qui peut refouler des gaz résiduaires dans une zone de combustion. Le système d'injection de vapeur étagé comprend, par exemple, un premier ensemble d'injection de gaz et un deuxième ensemble d'injection de gaz. Le premier ensemble d'injection de gaz est configuré pour injecter de la vapeur à un haut débit et une haute pression dans le nez de torche ou la zone de combustion. Le deuxième ensemble d'injection de gaz est configuré pour injecter un gaz (par exemple, de la vapeur et/ou un gaz autre que de la vapeur) à un bas débit et une haute pression dans le nez de torche ou la zone de combustion. L'invention concerne aussi un nez de torche contenant le système d'injection de vapeur étagé.
