2. Separator (oil production) - Wikipedia

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

   Oil and gas separators can operate at pressures ranging from a high vacuum to 4,000 to 5,000 psi. Most oil and gas separators operate in the pressure range of 20 to 1,500 psi. Separators may be referred to as low pressure, medium pressure, or high pressure. Low-pressure separators usually operate at pressures ranging from 10 to 20 up to 180 to ...

3. Oil production plant - Wikipedia

   en.wikipedia.org/wiki/Oil_production_plant

   the gas/oil ratio; the vapor pressure specification of the crude oil export stream; First stage separators in the Gulf of Mexico typically operate at 1500 to 1800 psi (103.4 to 124.1 bar), they operate as 2-phase liquid and vapour separators with a liquid residence time of 1 to 2 minutes. Produced water is removed in the low pressure (LP) 3 ...

4. Degasser - Wikipedia

   en.wikipedia.org/wiki/Degasser

   It operates at a low pressure to maximise the amount of gas (eg methane, carbon dioxide) that is removed from the water stream. [8] It can be located immediately downstream of the production separators prior to low pressure water treatment system such as dissolved gas flotation. In this case the degasser may also act as a surge drum to ensure a ...

5. Stock tank oil - Wikipedia

   en.wikipedia.org/wiki/Stock_Tank_Oil

   For a three stage train the operating pressures of the high, intermediate and low pressure separators might typically be: [4] HP separator: 1200 psig; IP separator: 200 psig; LP separator: 50 psig; Stock tank: 2 psig; The vapor pressure and relative volatility of constituent compounds is: [4]

6. Gas–oil separation plant - Wikipedia

   en.wikipedia.org/wiki/Gas–oil_separation_plant

   The high pressure is reduced at the choke valve to typically 7 to 30 bar at the separator, although the first stage separator could operate at higher pressure c. 250 bar. [2] Modern oil recovery practice may place a hydro-cyclone to replace the temporary GOSP, allowing the water to be removed immediately and re-injected into the reservoir.
