Title (EN) SODIUM NITROPRUSSIDE AND NITRATE FOR METABOLIC INHIBITION OF SULFATE-REDUCING MICROBES TO CONTROL SULFIDE PRODUCTION
(FR) NITROPRUSSIATE DE SODIUM ET NITRATE POUR L’INHIBITION MÉTABOLIQUE DE MICROBES RÉDUCTEURS DE SULFATE POUR CONTRÔLER LA PRODUCTION DE SULFURE
Abstract:
(EN) Combinations of a nitroprusside, such as sodium nitroprusside (SNP; Na2[Fe(CN)5NO]. 2H2O) and a nitrate, are provided, together with methods for the combined use of the nitroprusside and the nitrate as metabolic inhibitors of microbial cultures. The microbial cultures may include sulfate reducing bacteria (SRB) in aqueous culture. This metabolic inhibition may for example be implemented in the presence of a hydrocarbon, for example in an oil reservoir or in oil field systems and facilities. When applied to an SRB culture in the presence of a hydrocarbon, the combination of the nitroprusside and the nitrate may accordingly be used to ameliorate the biological formation of sulfides, particularly hydrogen sulfide.
(FR) La présente invention concerne des combinaisons d’un nitroprussiate, tel que le nitroprussiate de sodium (SNP ; Na2[Fe(CN)5NO].2H2O) et d’un nitrate, ainsi que des procédés d’utilisation combinée du nitroprussiate et du nitrate en tant qu’inhibiteurs métaboliques de cultures microbiennes. Les cultures microbiennes peuvent comprendre des bactéries réductrices de sulfate (SRB) en culture aqueuse. Cette inhibition métabolique peut, par exemple, être mise en œuvre en présence d’un hydrocarbure, par exemple dans des systèmes et des installations de réservoir de pétrole ou de champ de pétrole. Lorsqu’elle est appliquée à une culture de SRB en présence d’un hydrocarbure, la combinaison du nitroprussiate et du nitrate peut, en conséquence, être utilisée pour améliorer la formation biologique de sulfures, en particulier le sulfure d’hydrogène.
