Centrifuges for Diesel & Fuel Oil

Diesel Fuel Centrifuge

Reliable engine performance and prolonged life demand contaminant-free fuel. Alfa Laval diesel fuel centrifuges are designed to protect your engine room equipment by maintaining a clean diesel supply. They have proven their efficiency and reliability and have been used worldwide for decades. Installed between the storage tank and the day tank, these Alfa Laval diesel centrifuge modules remove water and sludge particles from the diesel fuel.

For heavy fuel and crude oils, Dolphin Centrifuge supplies a wide range of self-cleaning fuel purifiers. These are available as separate modules, and include pre-heaters and starter and PLC control panels.

A recent application using diesel fuel purifier for large scale black diesel recovery was supplied by Dolphin using Alfa Laval disc stack centrifuge (self-cleaning type).

How does a diesel centrifuge work?

Diesel centrifuge operation can be simply explained as follows. Under the extremely high centrifugal force inside the rotating bowl, the water & sludge are spun out towards the outer periphery of the centrifuge bowl while the clean diesel moves inwards and is continuously discharged through a ‘light-phase’ outlet. The water is collected and discharged through a separate passage from the bowl periphery. The separated sludge is periodically discharged by the ‘self-cleaning‘ mechanism built into the bowl.

Small Centrifuges for Diesel Purification on Work boats

Small foot-print Alfa Laval diesel centrifuges are designed for fuel & engine oil purification on vessels such as tugs, barges, yachts etc. Typically installed on day-tanks, these centrifugal diesel purifiers remove the water and sediment contamination providing a supply of clean fuel while keeping the lubricating oil clean. Shown below are diesel centrifuge packages of different capacities featuring Alfa Laval centrifuges.

Fuel Oil Centrifugal Purifier

Dolphin Centrifuge fuel oil centrifuges are fully automatic systems for the purification of light & heavy fuel oils. They feature Alfa Laval self-cleaning, disc stack, centrifugal separators.

The separation process is essential to remove contaminants such as heavy metals (vanadium, sodium, potassium etc.), as well as water and fuel sludge before the fuel is used.

Fuel Oil Purifier Application:

Contaminated fuel oil can cause premature failure of engine & turbine components due to corrosion, clogging and erosion of fuel system. Properly cleaned and treated fuel is usable in a range of gas turbine and IC engine power plants.

Features and Benefits:

• Meet turbine manufacturers fuel quality requirements
• Consistent fuel quality
• No pre-filtration required
• Reduced sludge volume for disposal (no filter cartridges)
• Fully automatic operation (minimal labor)
• No filter media related costs

Fuel Oil Purifier Operation:

Dolphin designed and manufactured fuel oil module will transfer untreated fuel oil through a pre-filtration and pre-heating system to the Alfa Laval centrifuge. The separated clean fuel oil is internally pumped by the centrifugal purifier to local storage tank which feeds the turbine or engine.
