ABSTRACT:
A method for minimizing sulfur contamination of refined hydrocarbon fluids transported in a pipeline for the transportation of sweet and sour hydrocarbon fluids by (a) mixing with the sour hydrocarbon fluids from 0 to about 2000 ppm of a corrosion inhibiting additive; (b) transporting the sour hydrocarbon through the pipeline; (c) transporting a sweet hydrocarbon wash solution containing from about 10 to about 2000 ppm of a mixture of light amines and heavy amines, up to about 2000 ppm of a corrosion inhibiting additive, up to about 500 ppm of a surfactant and up to about 1500 ppm of an alkanol containing from 1 to about 6 carbon atoms; and, (d) transporting refined hydrocarbon fluids containing up to about 200 ppm of a corrosion inhibiting additive, an amine having a molecular weight from about 31 to about 500 or mixtures thereof.
