Separators are used to separate oil, water and gases from crude extracted from well. This presentation describes different types of separators and their parts and functioning.

2. SEPARATORS
 Used to separate oil,gas and water.
 Used for efficient transportation and storage of oil and gas,as they need to be
stored separately.
 Prevent corrosion in transportation media by the removal of salts,if present in
water.
 Two types based on the fluid flow:
 2 phase separators (Oil+Water / Oil+Gas)
 3 phase separators(Oil+Water+Gas)
 Two types based on the arrangement :
 Vertical Separatos
 Horizontal Separators

3. VERTICAL SEPARATOR

4. VERTICAL SEPARATOR
 Mainly useful for offshore wells because of limited space.
 Can handle foamy or sluggish fluid.
 Difficult to repair and clean.

5. HORIZONTAL SEPARATOR

6. HORIZONTAL SEPARATOR
 Mailny used in onshore fields because they occupy large area.
 Can handle high flow rates.
 Easy to clean and maintain.
 Can handle foamy fluids,muds,slugs.

7. COMPONENTS OF SEPATATOR
 Separator has following main components :
 Primary Separation Section
 Baffles
 Oil Settling Section
 Water Drain Section
 Oil,Water and Gas outlets.
 Mist Extractor

8. PRIMARY SEPARATION SECTION
 Present at the entry to the separator.
 Most of the separation takes place here, as oil entering at high speed strikes
here,and oil,gas and water separate due to inertia.

9. OIL SETTLING SECTION
 Oil settles here, and gas, if present, separates from the top of the oil layer.
 At the bottom of this section, oil outlet pipe is present to extract separated oil and
is sent to transportation media.

10. BAFFLES
 Present between the oil and water settling section.
 Prevent backflow of fluids.
 Also separates particles with size between 140-300 microns.

11. MIST EXTRACTOR
 Present just before the gas outlet.
 Absorbs small oil molecules of size less than 140 microns.
 Categorised in 2 types:
 Mesh type
 Vein type
