Title (EN) COMPOSITION AND METHOD FOR ELIMINATION OF HYDROGEN SULFIDE AND MERCAPTANS
(FR) COMPOSITION ET PROCÉDÉ D'ÉLIMINATION DE SULFURES D'HYDROGÈNE ET DE MERCAPTANS
Abstract:
(EN) A scavenging composition and method for scavenging hydrogen sulfide and/or mercaptans from fluids. The scavenging composition comprises an alkali metal nitrite and a nitrogen-containing scavenger, and optionally an inorganic base, as a hydrogen sulfide and/or a mercaptan scavenger for hydrocarbon fluids, particularly for crude oil, field oil, fuel oil, straight run distillates, cracked distillates, residual fuels, natural gas, petroleum associated gas and the like.
(FR) La présente invention concerne une composition de dégazage et des procédés de dégazage de sulfure d'hydrogène et/ou de mercaptans présents dans des fluides. La composition de dégazage comprend un nitrite de métal alcalin et un épurateur contenant de l'azote, et éventuellement une base inorganique, en tant qu'épurateur de sulfure d'hydrogène et/ou de mercaptan pour des fluides hydrocarbonés, en particulier pour le pétrole brut, le pétrole de champs pétroliers, le mazout, les distillats de première distillation, les produits de distillation directe, les combustibles résiduels, le gaz naturel, le gaz associé au pétrole et analogues.
