Lube oil treatment

The quality of your lube oil determines engine lifetime. Efficient oil cleaning is crucial for minimizing marine engine wear and damage, and ensuring consistent operation at peak performance. Separators and automatic filters are recommended by engine manufacturers for continuous cleaning of circulating lube oil due to their high capacity in removing dirt, insoluble combustion products and water.

Longer lasting and cleaner lube oil with Alfa Laval MIB 503 Separator

Aboard the Prins Maurits – a Dutch fishing vessel – Chief Engineer Auke van Slooten has doubled the life expectancy of his main engine’s lube oil, saving 1,400 L of oil a year and nearly two hours of cleaning time per week using an Alfa Laval MIB 503 Separator.

Alfa Laval lube oil treatment

Lubrication oil is an essential part of vessel operations and plays an important role in engine efficiency and overall engine lifetime. The cleaner you can keep the lubrication oil, the better it is for the engine. Effective cleaning also means the oil needs to be replaced less often, saving time and money in the long-term. Alfa Laval can offer the optimal solution to ensure your lubrication oil stays cleaner and lasts longer, while helping to ensure that your engine stays protected.

Heat recovery for lubrication oil treatment system

Energy efficiency strongly influences a vessel’s cost effectiveness and its environmental footprint. Improving energy efficiency lowers fuel consumption and related cost. In addition, it makes the operation more environmentally friendly. By installing an Alfa Laval Heatpac® CBM heat exchanger, it is possible to recover excess heat energy downstream of the separator, re-purposing it to heat the oil prior to separation and thereby reduce the load on both the separator preheater and the cooling system.

Lube oil centrifugation

Lube oil centrifugation enables you to discard waste without the need to buy disposables such as filter cartridges. This makes lube oil cleaning more convenient, cost-effective and environment-friendly.

Powerful, productive and cost-effective

  • Removes both water and solids in one operation
  • Effective cleaning of even small particle sizes
  • Minimal maintenance, enabling more process uptime
  • Prolongs equipment lifetime
  • Low total cost of ownership (TCO)

Lube oil centrifugation uses a centrifugal force 5,000 times stronger than gravity to separate particles of different densities and continually directs cleaned oil back into your process. The water is released while the contaminating solids are stored separately. If your processes result in low amounts of solid waste, you can generally remove it manually. Higher waste amounts are automatically cleaned. Lube oil centrifugation can also handle large cleaning volumes and a temporary high influx of water.
