Steam generator additives to minimize fouling and corrosion in crude towers

A method of inhibiting fouling and corrosion in a refinery distillation tower and a steam generator, wherein said steam generator is configured to feed steam to said refinery distillation tower, said method comprising,

• feeding a dual action amine composition to said steam generator, said dual action amine composition comprising N,N-dimethylaminoethanol and at least one other dual action amine;
• and
• carrying said dual action amine composition in vapor phase from said steam generator to entry into said refinery distillation tower, and carrying said dual action amine along said refinery distillation tower in vapor phase,
• wherein said dual action amine composition aids in neutralizing acidic components in said steam generator, and serves to minimize fouling caused by salt deposits of amines in said refinery distillation tower.

A composition for inhibiting fouling and corrosion in a refinery distillation tower and steam generator, the composition comprising:

• (a) N,N-dimethylaminoethanol;
• (b) morpholine, N-hexylamine, N,N-dimethylcyclohexylamine, 1-Dimethylamino-2-propanol, t-butylmorpholine, Dimethyl-t-butanolamine, N-ethylmorpholine, N,N-dimethylmethoxypropylamine, methoxypropylamine, N-methylmorpholine, N,N-Dimethylmethoxyethylamine, trimethylamine, cyclohexylamine, 1-methylpyrrolidine, 1,4-dimethylpiperazine, N,N,N′,N′-tetramethylethylenediamine, 2-Aminomethylfuran, 1,2-Dimethylpropylamine, N-Methyldibutylamine, N-Methyldipropylamine, 2-Ethyl-1-hexylamine, N,N-Diethyl-propargylamine, N,N-dipropylamine, diallyl amine, pyrrolidine, 2-(methylamino)-ethanol, N,N,N′,N′-tetramethyl-1,3-propane diamine, 4-methylpyridine, N-methyl-2-aminomethylfuran, or mixtures thereof;
• and
• (c) N-octadecylamine, N-oleylpropanediamine, N-oleylamine, or mixtures thereof.
