Top 10 Questions for Oil Separator Interview

Essential Interview Questions For Oil Separator

1. Explain the working principle of an oil separator?

An oil separator works on the principle of gravity separation. The mixture of oil and water is introduced into the separator, where it is allowed to settle due to gravity. The oil, being lighter than water, rises to the top of the separator, while the water settles at the bottom. The separated oil can then be collected from the top of the separator, while the water is drained from the bottom.

2. What are the different types of oil separators?

Gravity Separators

  • API Separators
  • Parallel Plate Separators
  • Tilted Plate Separators

Coalescing Separators

  • Media Coalescers
  • Electrostatic Coalescers

3. What are the factors that affect the efficiency of an oil separator?

  • Oil droplet size
  • Specific gravity of oil and water
  • Flow rate
  • Temperature
  • Separator design

4. What are the applications of oil separators?

  • Industrial wastewater treatment
  • Oil spill cleanup
  • Automotive industry
  • Food processing industry
  • Oil and gas industry

5. What are the maintenance requirements for an oil separator?

  • Regular inspection and cleaning
  • Replacement of coalescing media or electrostatic grids
  • Monitoring of oil and water levels
  • Calibration of alarms and controls

6. What are the common problems associated with oil separators and how can they be resolved?

  • Oil carryover: This can be caused by high flow rates, small oil droplets, or poor maintenance. Possible solutions include increasing the separator size, using coalescing media, or optimizing the operating conditions.
  • Water carryover: This can be caused by low flow rates, large oil droplets, or poor design. Possible solutions include reducing the separator size, using gravity separators, or installing a coalescer.
  • Sludge accumulation: This can be caused by high solids content in the influent or poor maintenance. Possible solutions include regular cleaning, using a sludge removal system, or optimizing the influent conditions.

7. What are the latest advancements in oil separator technology?

  • Dissolved air flotation (DAF): This technology uses air bubbles to float oil droplets to the surface, which are then skimmed off.
  • Electrocoagulation: This technology uses an electrical current to destabilize oil droplets and promote coalescence.
  • Membrane filtration: This technology uses a semi-permeable membrane to separate oil from water.

8. How do you determine the size of an oil separator that is required for a specific application?

  • Determine the flow rate of the influent.
  • Determine the concentration of oil in the influent.
  • Select a separator that has a removal efficiency that is sufficient for the required application.
  • Calculate the required separator volume based on the flow rate and removal efficiency.

9. What are the environmental regulations that apply to oil separators?

  • Clean Water Act (CWA): This act regulates the discharge of pollutants into surface waters, including oil.
  • Resource Conservation and Recovery Act (RCRA): This act regulates the handling and disposal of hazardous waste, including oil.
  • National Pollutant Discharge Elimination System (NPDES): This program regulates the discharge of pollutants from industrial facilities into surface waters.

10. What are the career opportunities for oil separator professionals?

  • Oil separator design engineer
  • Oil separator sales engineer
  • Oil separator maintenance technician
  • Oil separator inspector
  • Oil separator researcher
