Principles and Operation of Production Separators
─ Gas, oil and water separation was achieved by
the difference in gravity, or weight, of each fluid.
─ Production separator do the same job, except they
are built to handle a continuous-flow stream and
have features to improve separation efficiency
under flow conditions.

Three general types of separators
─ Horizontal separator ─ for high-pressure and medium-pressure service
─ Vertical separator ─ for low-pressure service (generally) ─ Spherical separator ─ more compact and cheaper ─ limited separation space and liquid surge capacity ─ for low-volume remote platforms

Separation methods
─ Stage separation method
─ Low-temperature separation method

Stage separation method (two stage separation)
Any number of separators may be used in stage separation as long as stage operates at successively lower pressures.

Low-temperatures separation method
It is used to handle the production from high-pressure gas wells
Well fluids – a mixture of gas & some light liquids
Dehydration – the removal of water vapor from gas

Low-temperature separation method
For high-pressure gas wells (well fluids: mixture of gas and some light liquids)
─ Dehydration to remove water vapor from gas
