摘要： A sulfidic complexing agent is disclosed that includes a suspension or a solution formed by a reaction between a water-soluble metal compound and a water-soluble sulfidic compound. The sulfidic complexing agent has a pH of from about 5 to about 11 and a molar ratio of metal to sulfur of from about 0.1 to about 1,000. The sulfidic complexing agent is useful for removing elemental mercury from a hydrocarbon fluid by contacting the hydrocarbon fluid with the sulfidic complexing agent. The molar ratio of sulfur in the sulfidic complexing agent to mercury in the hydrocarbon fluid is from about 50 to about 2,500. Also disclosed is a method for concurrently transporting and removing a trace amount of volatile mercury in a CO2-containing natural gas stream extracted from a subterranean formation. The natural gas stream is transported in a pipeline into which the sulfidic complexing agent is injected. Also disclosed is a method for capturing gas phase elemental mercury from a gas stream in the overhead section of a crude oil distillation unit by contacting the gas stream with the sulfidic complexing agent in the overhead section of the distillation unit to form a treated gas stream.
