Systems and methods relate to measuring ammonium bisulfide concentration in a fluid sample. The system includes an electrolytic conductivity cell, a temperature sensor and an analyzer. Logic of the analyzer determines the ammonium bisulfide concentration based on signals received from the conductivity cell and the temperature sensor that are coupled to monitor the fluid.

Methods, systems and designs are provided for removing mercury from crudes. Crude oil containing a synthetic reducing agent is heated to a temperature above 100&#xb0; C. and held at that temperature for a specified period of time to convert all of the forms of mercury in the oil into the elemental mercury form. The elemental mercury is then stripped from the crude oil by e.g., flashing the hot oil and/or contacting it with a gas phase.

Process for removing mercury from crude oil

Methods, systems and designs are provided for removing mercury from crudes. Crude oil is heated to a temperature above 100&#xb0; C. and held at that temperature for a specified period of time to convert all of the forms of mercury in the oil into the elemental mercury form. The elemental mercury is then stripped from the crude oil by e.g., flashing the hot oil and/or contacting it with a gas phase. This process transfers the elemental mercury from the oil phase into the gas phase. Elemental mercury can then be removed from the gas phase by methods such as condensation, precipitation, or absorption either alone or in combination.

Removing mercury from crude oil

Methods, systems and designs are provided for removing mercury from crudes. Crude oil is heated to a temperature above 100&#xb0; C. in a stabilization column for a time sufficient to convert all of the forms of mercury in the oil into the elemental mercury form. The elemental mercury is then stripped from the crude oil by flashing, or preferably by gas stripping with a gas injected at the bottom of the column. Either process transfers the elemental mercury from the oil phase into the gas phase. Elemental mercury can then be removed from the gas phase by methods such as condensation, precipitation, or absorption either alone or in combination.

Methods and apparatus relate to treating fluid to at least reduce selenium content within the fluid. The treating includes conditioning stages to alter a composition of the fluid prior to removal of the selenium content from the fluid. The composition of the fluid after the conditioning stages facilitates the removal of the selenium content or at least limits detrimental impact to selenium removal efficiency.

Treatment stages for selenium removal

A method of selecting a mercury-contaminated solid surface followed by heating a cleaning solution to a temperature less than 100&#xb0; C. The cleaning solution can contain hydrocarbon oil and one or more organic sulfur compounds. Afterwards, the heated cleaning solution is contacted with the mercury-contaminated solid surface to remove the mercury contamination.

A process for removing naphthenic acids from an aqueous stream using a composition comprising calcium and activated carbon, and optionally a process for removing naphthenic acid and selenium compounds from an aqueous stream, is disclosed.

Naphthenic acid removal process

A process for removing selenium from an aqueous stream using a supported sulfur material, and optionally the addition of an activating agent for enhanced removal of selenite, is disclosed.

Selenium removal process

A process for removing selenium from an aqueous stream using a supported sulfur material, to convert selenocyanate to selenite, followed by removal of the selenite from the aqueous stream.
