Title
(EN) METHOD FOR INHIBITING CORROSION USING PHOSPHOROUS ACID
(FR) PROCEDE D'INHIBITION DE LA CORROSION AU MOYEN D'UN ACIDE PHOSPHOREUX
Abstract
(EN) The present invention relates to a method for inhibiting high temperature of corrosion-prone metal surfaces by organic acid-containing petroleum streams by providing an effective corrosion-inhibiting amount of phosphorous acid, typically up to 1000 wppm, to the metal surface.
(FR) L'invention concerne un procédé d'inhibition de la température élevée de surfaces métalliques sujettes à la corrosion en raison de flux de pétrole contenant un acide organique au moyen d'une quantité inhibitrice de corrosion efficace d'un acide phosphoreux, généralement jusqu'à 1000 wppm, appliqué sur la surface métallique.
