| 20090193969 | CONTAMINANT REMOVAL FROM A GAS STREAM - A system employing a regenerable zinc-oxide based sorbent to remove one or more contaminants from an incoming gas stream. The contaminant-depleted gas stream can then be used for any subsequent application, while at least a portion of the contaminant-laden sorbent can be regenerated via a step-wise regeneration process.

| 20100032344 | MERCURY REMOVAL FROM CRUDE OIL - 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. | 02-11-2010 |
| 20100032345 | MERCURY REMOVAL FROM CRUDE OIL - Methods and apparatus relate to removal of mercury from crude oil. Such removal relies on transferring mercury from a liquid hydrocarbon stream to a natural gas stream upon contacting the liquid hydrocarbon stream with the natural gas stream. Processing of the natural gas stream after used to strip the mercury from the liquid hydrocarbon stream removes the mercury from the natural gas stream. | 02-11-2010 |

| 20100210889 | MERCURY REMOVAL FROM HYDROCARBONS - 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. | 08-19-2010 |
| 20100213104 | SELENIUM REMOVAL PROCESS - Methods and apparatus relate to treating fluid to at least reduce selenium content within the fluid, which may be an aqueous liquid and form a feed stream. The treating removes selenium that may be present in compounds, such as selenocyanate, from the feed stream based on adsorption from contact of the fluid with a sorbent. Flowing a gaseous hydrogen sulfide and sulfur dioxide containing stream over a support, such as activated carbon, may provide the sorbent impregnated with sulfur and utilized in the treating of the fluid. | 08-26-2010 |
