7. Separator Purpose’s
Separators are mechanical devices for removing and collecting liquids from natural gas A properly designed separator will also provide for the release off entrained gases from the accumulated hydrocarbon liquids

8. Separator’s must perform the following
Cause a primary-phase separation of the mostly liquid hydrocarbons from those that are mostly gas
Refine the primary separation by removing most of the entrained liquid mist from the gas
Further refine the separation by removing the entrained gas from the accumulated liquid

9. Horizontal Separator
Horizontal separators are ideally suited for well streams having high gas-oil ratios, constant flow, and small liquid surge characteristics
Horizontal separators are smaller and less expensive

10. Higher gas velocities can be obtain due to two forces acting upon the liquid particles
( gravity and the horizontal force of the gas stream )
The horizontal separator has a much higher gas-liquid interface area than other types which aid in the release of solution gas and reduction of foam

11. The horizontal configuration is best suited for the two liquid phases.
In addition to being easier to hook up, easier to service , and easier to skid mount
Horizontal separators can be stacked in piggy back fashion to form stage separation assemblies and minimize horizontal space requirements

12. A well stream separator must
Discharge the separated gas and liquid from the vessel
and insure that no re-entrainment of one into the
other takes place
