The document discusses separators used in the oil and gas industry to separate oil, gas, and water for efficient storage and transportation. It describes two types based on fluid flow: two-phase and three-phase separators, and two arrangements: vertical and horizontal separators, each with its uses and maintenance considerations. Additionally, it outlines key components of separators, including primary separation section, baffles, oil settling section, water drain section, and mist extractor.

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
