2. API oil–water separator - Wikipedia

   en.wikipedia.org/wiki/API_oil–water_separator

   The API separator is a gravity separation device designed using Stokes' law principles that define the rise velocity of oil droplets based on their density, size and water properties. The design of the separator is based on the specific gravity difference between the oil and the wastewater because that difference is much smaller than the ...

3. Industrial wastewater treatment - Wikipedia

   en.wikipedia.org/wiki/Industrial_wastewater...

   An API oil-water separator, for removing separate phase oil from wastewater. [43]: 180 A clarifier, for removing solids from wastewater. [44]: 41–15 A roughing filter, to reduce the biochemical oxygen demand of wastewater. [44]: 23–11 A carbon filtration plant, to remove toxic dissolved organic compounds from wastewater. [43]: 210

4. Downhole oil–water separation technology - Wikipedia

   en.wikipedia.org/wiki/Downhole_oil–water...

   This allows the intake of a DOWS system to receive the petroleum and water mixture. In some types of DOWS systems, a pump will force the received mixture through the oil/water separation system. In some DOWS systems, the pressure of the fluids in the borehole will be enough to force the water-rich stream into a permeable zone below the DOWS system.

5. Separator (oil production) - Wikipedia

   en.wikipedia.org/wiki/Separator_(oil_production)

   A heated-water bath is probably the most effective method of removing foam bubbles from foaming crude oil. A heated-water bath is not practical in most oil and gas separators, but heat can be added to the oil by direct or indirect fired heaters and/or heat exchangers, or heated free-water knockouts or emulsion treaters can be used to obtain a ...

6. Oil–water separator - Wikipedia

   en.wikipedia.org/wiki/Oil–water_separator

   Downhole oil–water separation (DOWS) technology is an emerging technology that separates oil and gas from produced water at the bottom of the well, and re-injects most of the produced water into another formation which is usually deeper than the producing formation, while the oil and gas rich stream is pumped to the surface.

7. Separation process - Wikipedia

   en.wikipedia.org/wiki/Separation_process

   Oil-water separation, gravimetrically separates suspended oil droplets from waste water in oil refineries, petrochemical and chemical plants, natural gas processing plants and similar industries; Precipitation; Recrystallization; Scrubbing, separation of particulates (solids) or gases from a gas stream using liquid.

8. Centrifugal water–oil separator - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_water–oil...

   In a centrifugal oil and water separator, the force of gravity is one-thousand [citation needed] times greater that of the coalescing plate pack separator or the petrol interceptor, so the separation is much greater. Not only is the force of separation greater, but there are fewer working parts so maintenance is much easier and cheaper.

9. Oil production plant - Wikipedia

   en.wikipedia.org/wiki/Oil_production_plant

   Produced water, the densest phase, settles out at the bottom of the separator, oil floats on the top of the produced water phase, and gas occupies the upper part of the separator. [8] The separator is sized to provide a liquid residence time of 3 to 5 minutes which is sufficient for light crude oil (>35° API) as produced in the North Sea.
