Title (EN) METHOD FOR INHIBITING CORROSION USING CERTAIN PHOSPHORUS AND SULFUR-FREE AROMATIC COMPOUNDS
(FR) PROCEDE D'INHIBITION DE LA CORROSION A L'AIDE DE CERTAINS COMPOSES DEPOURVUS DE PHOSPHORE ET DE SOUFRE
Abstract: front page image
(EN)The persent invention relates to a method for inhibiting corrosion of corrosion-prone metal surfaces by organic acid-containing petroleum streams by providing an effective corrosion-inhibiting amount of sulfur and phosphorus-free aromatic compounds substitutedwith nitrogen,containing functional groups at the 5- or 3, 5-position, typically up to 1000 wppm, to the metal surface.
(FR)La présente invention concerne un procédé permettant d'inhiber la corrosion des surfaces métalliques susceptibles de se corroder facilement par des courants de pétrole à base d'acide, en fournissant une quantité efficace inhibitrice de corrosion contenant des composés aromatiques dépourvus de phosphore et de soufre sur la surface de métal. Ces composés sont substitués par de l'azote, et contiennent des groupes fonctionnels en position 5- ou 3,5, généralement jusqu'à 1000 ppm en poids.
