Treatment compositions for neutralizing acidic species and reducing hydrochloride and amine salts in a fluid hydrocarbon stream are disclosed. The treatment compositions may comprise at least one amine with a salt precipitation potential index of equal to or less than about 1.0. Methods for neutralizing acidic species and reducing deposits of hydrochloride and amine salts in a hydrocarbon refining process are also disclosed. The methods may comprise providing a fluid hydrocarbon stream and adding a treatment composition to the fluid hydrocarbon stream. The treatment compositions used may have a salt precipitation potential index of equal to or less than about 1.0 and comprise either water-soluble or oil-soluble amines.
A treatment composition for neutralizing acidic species and reducing hydrochloride and amine salts in a fluid hydrocarbon stream, said treatment composition comprising at least one amine selected from the group consisting of, 1,2 dimethylpropylamine, 1,4-dimethylpiperazine, N-methyldibutylamine, N-methyldipropylamine, ethylhexylamine, N-methylpyrrolidine, di-ethyl hydroxyl amine, dimethylcyclohexylamine, diethylpropargylamine, dimethyl-N-propylamine, di-N-propylamine, N,N,N′,N′-tetramethylethylenediamine (TMED), N-methyl piperidine, 2-dimethylamino 2-methyl 1-propanol (DMAMP), N,N,N′,N′-tetramethyldiaminomethane (TMMD), dimethyl tertiary butanolamine (DMTBA), dimethyl methoxypropylamine (DMMOPA), furfurylamine, and combinations thereof;
