Heavy Fuel Oil (HFO), also known as bunker fuel, or residual fuel oil, is the result or remnant from distillation of crude oil and has viscous tar-like consistency. HFO is heavily contaminated with several different compounds including aromatics, sulphur and nitrogen, making emissions upon combustion more polluting compared to other fuel types.
Due to untreated HFO’s viscosity, it requires considerable energy to heat and combust, compared with other hydrocarbon fuel types, because not enough oxygen is readily available. As a consequence, combustion is inefficient and incomplete, resulting in significant wastage of fuel and the production of extremely toxic emissions.
Although an intricate process, simply put, part of the solution comes from adding water to ‘oxygenise’ HFO. Adding a small amount of RemNOx HFO Fuel Emulsifier, combined with ultrasonic process equipment incorporating the technologies of SulNOx Group Plc, SCi Med and Hielscher Ultrasound GmbH, the fuel is permanently and efficiently emulsified with the added water. Tests have shown that a combination of only 2% of RemNOx HFO Fuel Emulsifier, 18% Water, and 80% HFO, result in an effective emulsion for maximum benefits.
With reduced viscosity of the new emulsion, this forms the basis of a fuel ready to combust more completely, with less required energy, and with less resultant toxic pollutants.
Remarkably, resultant emulsified HFO remains stable for a very long period, a trait which is unparalleled.
