ETHOXYLATED FATTY DIAMINE AS A CORROSION INHIBITOR FOR PIPELINES AND STORAGE TANKS

A corrosion inhibition composition includes a carrier fluid and corrosion inhibitor consisting essentially of a compound represented by Formula (I) where R1, R2, R3, and R4 are each, independently, a hydrogen or an alkoxy group, and m and n are each, independently integers ranging from 2 to 10, wher...

Beschreibung
Zusammenfassung:	A corrosion inhibition composition includes a carrier fluid and corrosion inhibitor consisting essentially of a compound represented by Formula (I) where R1, R2, R3, and R4 are each, independently, a hydrogen or an alkoxy group, and m and n are each, independently integers ranging from 2 to 10, where R5 and R6 are each, independently, a saturated C6-C10 hydrocarbon group or an unsaturated C6-C10 hydrocarbon group. A method of producing a corrosion inhibition composition consisting essentially of an ethoxylated diamine corrosion inhibitor and a carrier fluid and a method for inhibiting corrosion in a refined hydrocarbon-bearing system are also described. Une composition d'inhibition de corrosion comprend un fluide porteur et un inhibiteur de corrosion constitué essentiellement d'un composé représenté par la formule (I) où R1, R2, R3 et R4 sont chacun, indépendamment, un hydrogène ou un groupe alcoxy, et m et n sont chacun, indépendamment des entiers allant de 2 à 10, où R5 et R6 sont chacun, indépendamment, un groupe hydrocarboné C6-C10 insaturé ou un groupe hydrocarboné C6-C10 insaturé. L'invention concerne également un procédé de production d'une composition d'inhibition de corrosion consistant essentiellement en un inhibiteur de corrosion de diamine éthoxylée et un fluide porteur, ainsi qu'un procédé d'inhibition de la corrosion dans un système de support d'hydrocarbures raffiné.
