    摘要： A process for decreasing the level of elemental mercury contained in a crude oil at the well site by separating the crude oil stream into a gaseous hydrocarbon stream containing hydrocarbons, mercury and water, and a liquid hydrocarbon stream containing hydrocarbons and elemental mercury; removing mercury from the gaseous hydrocarbon stream in a mercury removal unit, thereby forming a treated gas stream; contacting a recycle gas stream comprising a portion of the treated gas stream with at least a portion of the liquid hydrocarbon stream for transfer of at least a portion of the elemental mercury contained in the liquid hydrocarbon stream to the recycle gas stream; thereby forming a mercury rich gas stream, and a treated liquid hydrocarbon stream; and passing the mercury rich gas stream, along with the gaseous hydrocarbon stream, to the mercury removal unit, is disclosed.

    摘要： A process is disclosed for removing heavy metals from a hydrocarbon gas stream by contacting the hydrocarbon gas stream, which contains a heavy metal and less than 10 ppm oxidizing compounds, with a composition containing a molecular sieve and sulfur resulting in a treated stream containing less heavy metal than the hydrocarbon gas stream; wherein the molecular sieve contains alumina, silica, and iron, and optionally copper and zinc. Optionally, the hydrocarbon gas stream can also contain a sulfur compound.

    摘要： A process is disclosed for removing mercury from a liquid hydrocarbon stream by contacting the mercury-containing liquid hydrocarbon stream with ferrous halide at moderate temperatures and without preheating the liquid hydrocarbon stream, or subjecting the liquid hydrocarbon stream to a heat treating step, immediately prior to contact with the ferrous halide particles.
