Heat Recovery for Lube Oil Treatment EnergyMaster


Cost saving has become a very attractive proposition on board of ships as the operating costs have risen sharply. The overall economy and less consumption of fuel are essential to be more competitive and to operate a green and environmentally friendly vessel.

Easy cost saving for lube oil treatment systems

In traditional lube oil treatment systems the energy for heating the lube oil upstream of the centrifugal separator is lost, because after separation the hot oil goes back to the engine sump tank to be cooled by the engine cooling system. As an integral part of the lube oil treatment system in compact unit design the GEA EnergyMaster recovers part of this energy. The recovery heat exchanger is the heart of this system and designed as a brazed plate heat exchanger.

The GEA EnergyMaster is available as:

  • An integrated part of the heater unit, HRU
  • A retrofit package for existing heater units

The return of investment period is outstanding short even for retrofit systems.

The return of investment period is outstanding short even for retrofit systems. The cold dirty oil inlet to the separator system is pre-heated by the recovery heat exchanger before the dirty oil is heated up to separating temperature by the standard steam, thermal oil or electric pre-heater. The hot clean oil outlet of the separator is used for pre-heating the cold dirty oil inlet. The footprint is not larger with separator systems in compact unit design. The system contains a brazed plate heat exchanger, a mounting plate, by-pass lines and isolating valves. The EnergyMaster is easy to handle, self-regulating and maintenance free.

Technical Data:

Example heat recovery calculation

  • Throughput capacity: 12,000 l / h
  • Inlet temperature from separator: 90 °C
  • Outlet temperature to sump tank: 80 °C
  • Capacity saving :63 kW power or 104 kg / h steam
