Corrosion inhibition system
Oil-dispersible corrosion inhibiting solutions are described which contain an ethoxylated tertiary amine along with an organic corrosion inhibitor in a solvent. The inhibiting solutions containing the instant ethoxylated amines are effective in reducing corrosion rates in the oil field. A preferred corrosion inhibiting solution contains one percent to 10% by wt of the ethoxylated amines, and 20 to 35% by wt of an organic inhibitor. The organic inhibitor systems are formed by the reaction of a mixture of a first amide and (an amine or imidazoline) or a mixture of one or more amides with organic acids predominantly having 15 to 20 carbon atoms/carboxylic acid group at a temperature of 70 to 100/sup 0/C. The formulation is particularly effective against hydrogen sulfide and carbon dioxide corrosion. 28 claims.
