Regardless of their configuration, Two Phase Gas–Oil separators, also known as Low Pressure Production Trap (LTTP), usually consist of four functional sections:

1. Section A: Initial bulk separation of Oil and Gas takes place in this section. The entering fluid mixture hits the inlet diverter. This causes a sudden change in momentum and, due to the gravity difference, results in bulk separation of the Gas from the Oil. The Gas then flows through the top part of the separator and the Oil through the lower part.
2. Section B: Gravity settling and separation is accomplished in this section of the separator. Because of the substantial reduction in Gas velocity and the density difference, Oil droplets settle and separate from the Gas.
3. Section C: Known as the Mist extraction section, it is capable of removing the very fine Oil droplets which did not settle in the gravity settling section from the Gas stream.
4. Section D: This is known as the liquid sump or liquid collection section. Its main function is collecting the Oil and retaining it for a sufficient time to reach equilibrium with the Gas before it is discharged from the separator.
