1. Introduction

• Purpose is to clean fluids• Different cleaning methods

2. Usage of separators• 2.1 Industry separators - Crude oil product - Food industry

(edible oil, milk) - Pharmaceutical - Chemical - Petrochemical

processes - Treatment of

industrial fluids

• 2.2 Marine separators - HFO - Lubricating Oil - Bilge oil separator - Evaporating water separator

3. General information about marine separators

• Bowl rotating and centrifugal force

• Gravity disc

• Water seal• Operating water• Water for rinsing

4. Fuel oil and lubrication oil separators

• Purifier eliminates contaminants • Clarifier eliminates high density impurities• Why is it important to separate HFO and LO?

5. Parts

• 1: Product feed,•  2: Disc stack, • 3: Separating disc, • 4: Concentrate chamber, • 5: Nozzles, • 6:Centripetal pump for light phase, • 7: Discharge of light phase, • 8: Centripetal pump for medium phase, • 9: Discharge of medium phase, • 10: Feed for wash water or concentrate recycle

• Bowl

• Disc stack & Distributor

• Paring disc

• Gravity discs

• Heater

6. How it works

• The contaminated product is pumped to the separator• Separation takes place inside a rotating bowl• Light phase is discharged through the outlet pipe• Water forms a seal around the outer edge• The solids collect in the periphery where they are discharged

7. Troubleshooting and maintenance

• Emulsion

• Suspension

• Unsuitable gravity disc

• Deposit accumulation

• Maintenance and repair manual

8. Conclusion

• Simple handling and maintenance

• Greater security of facility

• Lower operation costs
