摘要： Trace element levels of heavy metals in crude oil are reduced by contacting the crude oil with an oxidizing agent, extracting heavy metals into a water phase for subsequent separation from the crude oil. The oxidizing agent is selected from the group of hydroperoxides, organic peroxides, inorganic peracids and salts thereof, organic peracids and salts thereof, and ozone. In one embodiment, the oxidizing agent converts heavy metals into the heavy metal cations in a water-oil emulsion, which can be subsequently separated from the crude oil, for a treated crude oil having reduced levels of heavy metals. In one embodiment, at least a complexing agent can be added to facilitate the removal by forming soluble heavy metal complexes in the water phase.

摘要： Methods and systems relate to the in-situ removal of heavy metals such as mercury, arsenic, etc., from produced fluids such as gases and crudes from a subterranean hydrocarbon-bearing formation. A sufficient amount of a fixing agent is injected into formation with a dilution fluid. The fixing agent reacts with the heavy metals forming precipitate, or is extracted heavy metals into the dilution fluid as soluble complexes. In one embodiment, the heavy metal precipitates remain in the formation. After the recovery of the produced fluid, the dilution fluid containing the heavy metal complexes is separated from the produced fluid, generating a treated produced fluid having a reduced concentration of heavy metals. In one embodiment, the dilution fluid is water, and the wastewater containing the heavy metal complexes after recovery can be recycled by injection into a reservoir.

摘要： A method for simultaneously transporting and removing trace amount levels of heavy metals from produced fluids such as crude oil, with the injection of a fixing agent into the pipeline for use in transporting the produced fluid. A sufficient amount of the fixing agent is injected into the pipeline containing the produced fluid and a dilution fluid. The fixing agent reacts with the heavy metals forming precipitate or soluble complexes in the dilution. The dilution fluid containing the heavy metal complexes is separated from the produced fluid, generating a treated produced fluid having a reduced concentration of heavy metals. In one embodiment, the dilution fluid is water, and the wastewater containing the heavy metal complexes after recovery can be recycled by injection into a reservoir.

摘要： Trace levels of mercury in a natural gas are reduced by scrubbing the natural gas in an absorber with an aqueous solution comprising a water-soluble sulfur compound. The water-soluble sulfur compound reacts with a least a portion of the mercury in the natural gas to produce a treated natural gas with a reduced concentration of mercury, and a mercury containing sulfur-depleted solution which can be disposed by injection into a (depleted) underground formation. The produced water extracted with the natural gas from the underground formation can be recycled for use as the scrubbing solution. In one embodiment, a fresh source of water-soluble sulfur compound as feed to the absorber can be generated on-site by reacting an elemental sulfur source with a sulfur reagent in produced water.
