Title
(EN) METHODS AND SYSTEMS FOR SUPPRESSING CORROSION OF STEEL SURFACES
(FR) PROCÉDÉS ET SYSTÈMES POUR ÉLIMINER LA CORROSION DES SURFACES EN ACIER
Abstract
(EN)
Certain metal surfaces are often unable to be contacted effectively with fluids containing hydrofluoric acid due to significant corrosion issues. Steel surfaces represent but one example. Corrosion inhibitor compositions comprising an N-(phosphonoalkyl)iminodiacetic acid or any salt thereof can be used to suppress corrosion of steel surfaces, including those that contain multiple types or grades of steel. Methods for suppressing corrosion of a steel surface can comprise: contacting a steel surface with a corrosive environment, the corrosive environment comprising hydrofluoric acid; exposing the steel surface to a corrosion inhibitor composition, the corrosion inhibitor composition comprising an N-(phosphonoalkyl)iminodiacetic acid or any salt thereof; and suppressing corrosion of the steel surface being contacted with the corrosive environment through exposure to the corrosion inhibitor composition.

Certaines surfaces métalliques sont souvent incapables d'être mises efficacement en contact avec des fluides contenant de l'acide fluorhydrique en raison de problèmes de corrosion significatifs. Les surfaces en acier en sont un exemple. Selon l'invention, des compositions anti-corrosion comprenant un acide N-(phosphonoalkyl)iminodiacétique ou un sel de celui-ci peuvent être utilisées pour éliminer la corrosion des surfaces en acier, y compris celles comportant de multiples types ou qualités d'acier. L'invention concerne également des procédés d'élimination de la corrosion d'une surface en acier pouvant comprendre : la mise en contact d'une surface en acier avec un environnement corrosif, l'environnement corrosif comprenant de l'acide fluorhydrique ; l'exposition de la surface en acier à une composition anti-corrosion, la composition anti-corrosion comprenant un acide N-(phosphonoalkyl)iminodiacétique ou un de ses sels ; et l'élimination de la corrosion de la surface en acier en contact avec l'environnement corrosif par exposition de celle-ci à la composition anti-corrosion.
