(EN) CORROSION INHIBITOR COMPOSITIONS AND METHODS OF USING SAME
(FR) COMPOSITIONS INHIBITRICES DE LA CORROSION ET LEURS PROCÉDÉS D'UTILISATION
Abstract
(EN)
Disclosed are methods for inhibiting the corrosion of metal containments such as carbon-steel pipes used in oil recovery processes, the methods comprising adding urine and/or compositions comprising urine to water sources to form corrosion inhibitor compositions, and contacting metal containments with the corrosion inhibitor compositions. The water sources are for example aqueous solutions that are corrosive to metal containments such as carbon-steel pipes. Compositions comprising urine that provide reduced corrosion or corrosion inhibition are also described. Metal containment assemblages comprising corrosion inhibitor compositions and a metal containment are also described.

L'invention concerne des procédés permettant d'inhiber la corrosion de contenants métalliques tels que des tuyaux en acier au carbone utilisés dans des processus de récupération du pétrole, lesdits procédés consistant à ajouter de l'urine et/ou des compositions comprenant de l'urine à des sources d'eau pour former des compositions inhibitrices de la corrosion, et à mettre en contact les contenants métalliques avec les compositions inhibitrices de la corrosion. Les sources d'eau sont par exemple des solutions aqueuses qui sont corrosives pour des contenants métalliques tels que des tuyaux en acier au carbone. L'invention concerne également des compositions comprenant de l'urine qui permettent d'obtenir une corrosion réduite ou une inhibition de la corrosion. L'invention concerne également des assemblages de contenant métallique comprenant des compositions inhibitrices de la corrosion et un contenant métallique.
