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.

Process of removing metal contaminants from light hydrocarbons

An effective amount of at least one second bacteria may be added to a wastewater stream within a water treatment system. The wastewater stream may have or include an aqueous-based fluid, a first bacteria and organic acids. The second bacteria may be or include, but is not limited to facultative bacteria, spore-forming bacteria, phenol degrading bacteria, denitrifying bacteria, organic acid-degrading bacteria, high temperature bacteria, and combinations thereof. The addition of the second bacteria the wastewater treatment system may at least partially reduce the amount of the organic acids within the wastewater stream as compared to an otherwise identical wastewater stream in the absence of the second bacteria.
