Abstract

La présente invention concerne des procédés de formation d'un film durable d'inhibition de corrosion sur la surface de métaux dans des systèmes de traitement de pétrole brut, par ajout périodique d'un composé feuillogène contenant du phosphore. Cet ajout périodique de composé inhibe la corrosion tout en éliminant le besoin coûteux en dosages d'entretien continus.
