Separator Internals1Gas / Water/ Oil Separation
2Vessel Internals3Vessel Internals
4Inlet DiverterFunction ~ disengage the gas and liquid .
Types - baffle plates can be a spherical dish, flat plate, angle iron, cone
5Inlet DiverterFunction ~ disengage the gas and liquid .
Types - centrifugal diverters
6Wave BreakersFunction ~ dampen any wave action that caused by incoming fluids
Vertical baffles
Place perpendicular to the flow
In liquid collection section
Install in long horizontal vessel
Why eliminate wave?Liquid control problem Reduce separation 7Wave Breakers
8Defoaming PlatesFunction ~ to aid in coalescence of the foam bubbles.
Inclined parallel plates or tubes to promote coalescence, or merging, of the foam bubbles liberated from the liquid.
9Defoaming Plates
10Vortex BreakerVortex- a whirling mass of fluid or air, especially a whirlpool or whirlwind
A vortex breaker is a device used in engineering to stop the formation of a vortex when a fluid (liquid or gas) is drained from a vessel
The formation of vortices can entrain vapor in the liquid stream, leading to poor separation in process steps such as distillation or excessive pressure drop or causing cavitation of downstream pumps
Some use radial vanes or baffles around the liquid exit 11Vortex Breaker
12Sand Jets and DrainsThe Sand Jetting system is commonly used in the upstream separator to remove solids that settles in gravity separators.
It fluidizes the solids with pressurized water introduced through specially designed nozzles.
The solids are then discharged through sand drains located down the length of the vessel13Mist ExtractorFunction ~ to remove liquids mist from gas stream
Made of wire mesh, vanes, centrifugal forces devices
Liquid droplets impinge on the matted wires and coalesce
Effectiveness of wire mesh depends largely on the gas velocity.
High ~the liquids knocked out will be re-entrained.

15Mist Extractor
16Mist Extractor
17Coalescing PlatesSpecific for oil/water separation
Function~ increase size of water droplets in oil phase.
Make gravity settling easier
Problem face ~ plugging with solids particles
