E-Fuel, Heavy Fuel Oil Emulsion

Pollution and Inefficiency, Meet E-Fuel! Many Industries around the world rely on Fuel Oils to conduct operations. These fuels are notorious for being low quality and high in sulfur, asphaltenes and vanadium. A consequence of these undesirable features are high particulate emissions and levels of SO3 (sulfur trioxide), as well as high levels of corrosion and deposits due to the incomplete combustion process (as typically found with most inferior fuels).Through the use of patented, innovative technologies, E-Fuel SA has developed specific methods in which to permanently stabilize emulsified fuels. These methods make it possible to improve both efficiency and performance of boilers and engines. Most importantly, these innovations more than successfully reduce both harmful emissions and unburnt fuel.

E-Fuel, Success Through Innovation

Great lengths have been taken by the scientists at E-Fuel to silence the most disconcerting critics towards emulsified fuels. Precision manufacturing, ease of operation, long lifespan and low maintenance requirements are a few of the main features of E-Fuel emulsion technologies. Because of its low overall cost and strong economic advantages, the technologies made available by E-Fuel assure a quick return on investment.

Technical BenefitsFuels produced with E-Fuel’s patented emulsification process assist in improving overall efficiency of steam and industrial boilers as well as industrial ovens. In addition to standard diesel fuel, E-Fuel makes it possible to emulsify HFO, marine bunker and heavy bunker oils. • Less consumption = less cost• Low maintenance cost • Complete combustion = improved efficiency of boilers, ovens and engines• Fully customizable applications

• Choose the percentage of emulsion and quality of fuel and adapt to your specific need (storage, transport, heating...)

Environmental BenefitsBattling global warming is a constant struggle. E-Fuel has effectively developed a way for companies and individuals alike to increase productivity and cut costs while simultaneously protecting the environment.E-Fuel’s patented emulsification process offers a valuable solution for immediate reduction in emissions, ash and the production of black smoke along with: • Reduced particulate emissions• Lower soot production, studies confirm by as much as 90%• Verified reduction of harmful emissions (verified through independent

laboratories and users)

The Economics of E-Fuel Make $$$Combustion of hydrocarbons are complete when all available fuel is transformed into Carbon Dioxide and all Hydrogen is transformed into water vapor.Combustion efficiency is directly related to Oxygen levels. Therefore, the lower the Oxygen content, the greater performance and fuel savings.Each percentage point increase in combustion efficiency corresponds to 3% of energy saving (oil use).

The industrial cost of an emulsion with the shown mixture of components is 15% lower than the cost of conventional fuel oils.

• In the 12% HFO emulsion, CO emissions are reduced by 82%

• The NOx emissions are reduced by about 20%• Boiler efficiency remained unchanged. • CO2 remained unchanged.

Pre-heating temperature of HFO (no emulsion) was 338°F (170°C) while HFO with 12% emulsion was 280°-284° F (138°-140°C).

E-Fuels patented surfactant delivers oxygen to the combustion process. As a result, the air regulation shutter could be further closed without causing emission elevations in CO and providing an increase in boiler efficiency.

NOTE:The improvised HFO burner with the boiler formerly run with diesel oil was poorly adapted however showed the correct trend of emission reduction.

The emulsion remained homogeneous and stable. The product was held in an open tank with a return connection to the burner at 280°F (140°C), being subjected to continuous changes in temperature and thereafter to ambient temperature , the product did not suffer any falling or separations.

• In the 18% HFO emulsion, CO emission are reduced by 82% • The NOx emissions are reduced by about 40%• Boiler efficiency improved by 2%• CO2 remained unchanged.

Pre-heating temperature of HFO (no emulsion) was about 338°F (170°C) while HFO with 18% emulsion was about 248° -266° F (120°-130°C).
