Abstract
A method of removing a metal contaminant from a light hydrocarbon stream comprises introducing a light hydrocarbon stream into a reactor vessel, the reactor vessel containing an aqueous treatment composition which comprises a treatment agent comprising one or more of the following: an alkali metal salt of a thiocarbonate; an alkaline earth metal salt of a thiocarbonate; an alkali metal salt of a tetrathioperoxy carbonate; or an alkaline earth metal salt of a tetrathioperoxy carbonate, the light hydrocarbon stream having an API gravity of greater than 28 degree determined in accordance with ASTM D 287-12 and comprising a metal contaminant; contacting the light hydrocarbon stream with the aqueous treatment composition generating a treated light hydrocarbon stream with a reduced level of the metal contaminant; and removing the treated light hydrocarbon stream from the reactor vessel.
