摘要： A method for concurrently transporting and removing trace amount levels of heavy metals such as mercury from produced fluids such as natural gas, with the injection of a complexing agent and a hydrate inhibitor into the pipeline for use in transporting the produced fluid. Volatile mercury in the natural gas is removed while the produced fluid is being transported in the pipeline, with the hydrate inhibitor suppressing or decreasing the formation of the hydrate that would cause plugging in the pipeline. The complexing agent reacts with the volatile mercury in the natural gas, forming precipitate or soluble mercury complexes in the aqueous phase. The aqueous phase containing the hydrate inhibitor, unreacted complexing agent, and mercury complexes is subsequently recovered and can be re-used in the pipeline.

摘要： Disclosed herein is a method for improving the total energy demand required to separate carbon dioxide (CO2) from an aqueous ionic absorbent solution in a post-combustion carbon capture process. The method involves (a) contacting a flue gas stream containing CO2 with an aqueous ionic absorbent solution under absorption conditions to absorb at least a portion of the CO2 from the flue gas stream and form a CO2-aqueous ionic absorbent solution stream, wherein the aqueous ionic absorbent solution comprises one or more diluents and an ionic absorbent containing a cation and an anion comprising an amine moiety; and (b) subjecting at least a portion of the CO2-aqueous ionic absorbent solution stream to desorption conditions to form a CO2-rich stream and an aqueous ionic absorbent solution stream having a reduced CO2 content.

摘要： Trace levels of mercury in a natural gas are removed in a gas processing plant in an amine unit and / or a dehydrator. The mercury removal occurs concurrently with the removal of acid gases in an amine unit, e.g., an absorber or scrubber, with an amine solution containing a complexing agent. The mercury removal can also be carried out concurrently with the removal of water in a glycol dehydrator with the addition of a complexing agent to the glycol solution. Volatile mercury in the natural gas is removed by the complexing agent, forming non-volatile mercury species in the rich amine / glycol solution.

摘要： Particulate mercury, in the form of metacinnabar, is removed from crude oil by thermally treating the crude oil at temperatures in a range from 150°C to 350°C and at a pressure sufficient to limit the amount of crude vaporizing to no more than 10 wt. %. In the thermal treatment, the particulate mercury is converted into elemental mercury, which can be removed by directly adsorption from the crude onto a support. In one embodiment, the elemental mercury can be removed by stripping the crude with a gas, and then adsorbing the mercury onto a support. The crude oil can be optionally treated prior to stabilization and contains 0.1 wt. % or more of C4-hydrocarbons. Following the thermal treatment, the treated crude is cooled and the pressure is reduced. The C4- hydrocarbons then vaporize from the crude and carry the elemental mercury with them. The elemental mercury in this hydrocarbon gas stream may then be removed by a solid adsorbent.

摘要： Trace element levels of mercury in crude oil are reduced by first passing the crude oil through a filtration device to generate filtered crude having a reduced concentration of mercury and a reject stream having a concentrated mercury level. In one embodiment, the filtration device is back-flushed to generate the reject stream. In another embodiment, the reject stream comprises a portion of the retentate from a cross-flow filter device. The reject stream is treated with an extractive agent selected from tetrakis (hydroxymethyl)phosphonium sulfate; tetrakis(hydroxymethyl) phosphonium chloride; an oxidizing agent; an organic or inorganic sulfidic compound to extract a portion of the mercury into a water phase for subsequent removal. In one embodiment, the extractive agent is a reductant to convert non-volatile mercury into volatile mercury.

摘要： Trace amount levels of non-volatile mercury in crude oil are reduced by contacting the crude oil with a water stream containing at least a monatomic water-soluble sulfur species such as sulfides and hydrosulfides. The non-volatile mercury is extracted into the water phase forming a mercury rich wastewater, yielding a treated crude oil having at less than 50% of the original non-volatile mercury level. The wastewater can disposed or recycled by injection into a reservoir. In one embodiment, the water stream consists essentially of produced water.
