Title
(EN) FLARE SYSTEM USING PRODUCED WATER AND OZONE INJECTION
(FR) SYSTÈME DE TORCHE UTILISANT DE L'EAU PRODUITE ET UNE INJECTION D'OZONE
Abstract
(EN)
A system and apparatus for treating and disposing of produced water in conjunction with flared gas, thereby avoiding problems associated with injecting produced water back into subsurface strata. The system is installed at or near the wellhead where produced water being treated is at a higher temperatures. Produced water is treated with ozone injection in a scrubber with heat applied through a flare gas field burner, which uses field gas from oilfield operations. A wet scrubber unit with scrubber packing is used to clean emissions. A produced water pump is used to circulate produced water, and pump produced water through spray nozzles in the scrubber unit for use as the wet scrubbing agent. As produced water evaporates, evaporated salts and solids are continuously removed from the evaporator/scrubber unit by appropriate means, such as an auger system.
(FR)
L'invention concerne un système et un appareil pour traiter et éliminer l'eau produite conjointement avec un gaz de torche, ce qui permet d'éviter les problèmes associés à la réinjection d'eau produite dans des strates souterraines. Le système est installé au niveau ou à proximité de la tête de puits où l'eau produite en cours de traitement est à des températures élevées. L'eau produite est traitée par injection d'ozone dans un épurateur avec de la chaleur appliquée à travers un brûleur de champ de gaz de torche, qui utilise un gaz de champ provenant d'opérations de champ pétrolifère. Une unité d'épurateur par voie humide pourvue d'une garniture d'épurateur est utilisée pour purifier les émissions. Une pompe à eau produite est utilisée pour faire circuler de l'eau produite, et pomper de l'eau produite à travers des buses de pulvérisation dans l'unité d'épurateur pour une utilisation en tant qu'agent de lavage humide. A mesure que l'eau produite s'évapore, les sels évaporés et les solides sont retirés en continu de l'unité évaporateur/laveur par des moyens appropriés, tels qu'un système de tarière.
