  • www.wasp-pfs.com The production of diesel fuels containing FAME (biodiesel) is increasing in Europe as a consequence of the following EU Directives: 2003/30/EC (Biofuels) 2009/28/EC (Renewable Energy Directive) 2009/30/EC (Fuel Quality Directive) The new specification (Introduced Jan 1st 2011) EN590 Specification • Diesel, derv (white diesel) MDO, red diesel, gas oil, fuel oil; all middle distillate derivatives • Biodiesel/FAME (fatty acid methyl ester) content • 7% FAME blend is not in all fuels, but... • Fuel manufacturers/importers have informed us they only want to sell one blend, so 7% has to be the assumption • Low sulphur content (10ppm) • Aim: to approach becoming carbon neutral
  • www.wasp-pfs.com Although the EU aims for more sustainable fuel, the chemical composition of biodiesel causes a number of fuel quality issues, including poor fuel stability, microbiological contamination and an acceleration of fuel decay. In particular, the hygroscopic nature of bio-diesel significantly increases the saturation level, meaning the water content in fuel is well above the maximum specified level. This causes many concerns, which worsen if the fuel tank is outside or not in a temperature controlled environment. Water in fuel is at the root of microbial growth, waxing, sludge, bacterial infections, sediments and other foreign matter.
  • www.wasp-pfs.com A little bit more about Bio-Diesel • Biodiesel blends reduce a fuel’s carbon footprint • Biodiesel in EN590 can be made from any source (no effective regulation) • Infected fuel can have significantly higher acidity levels • Poor oxidisation stability compared to mineral fuels • Higher viscosity and density than mineral fuels • Lower energy content than mineral fuels • Compatibility issues with some metals, plastics and rubbers Fuel without biodiesel naturally decays, and could be out of specification after 6-12 months. However, bio-diesel causes fuel to decay much faster than natural fuel (with pure biodiesel decaying after a few weeks). It is therefore recommended blended fuels are only stored for up to 6 months to reduce contaminations.
  • www.wasp-pfs.com Typical contaminations • Water • Microbial growth • Waxing • Bacterial infection • Sediment Water in fuel • Free water (water separated from fuel) • Emulsified water (fuel looks cloudy)
  • www.wasp-pfs.com Water in fuel is at the root of microbial growth, waxing, sludge, bacterial infections, sediments and other foreign matter. These microbial contaminations can lead to corrosion of pipe work, cause fuel blockages and cause damage to the tanks and the engine’s injectors. Furthermore the lack of lubricant in biodiesel decreases the engines efficiency. This increases the temperature, causing component wear, wasting electricity and potentially good quality fuel as well as leading to back-up generator when it’s running during an emergency situation.
  • www.wasp-pfs.com Fuel Biomass Water Waxy deposits Contaminated fuel taken from a back-up generator
  • www.wasp-pfs.com Contaminated fuel • Unusable in some cases • Potential to stop, damage or destroy engines/generators • Costly disposal • Massive carbon impact in disposal • Cost of replacement fuel • Health and safety risk • Your business continuity plan is in danger
  • www.wasp-pfs.com “The increased use of FAME introduces new challenges.”.. “and requires strict application of good housekeeping practices throughout…” + Source: CONCAWE Report 9/09 “Proper control of water and sediments is therefore essential for preventing microbiological problems. This can be achieved by a combination of periodic sampling and testing of storage tanks and immediate removal of any water or sediment that is present.” + Source: CONCAWE Report 9/09 Fuel Quality and Emissions Management Group “Establish a system for filtering the contents of the main storage tank through a re-circulating filter system. ” + Source: Long Term Diesel Storage.

  • www.wasp-pfs.com To prevent fuel contamination occurring, WASP PFS Ltd and the CONCAWE group suggests applying strict ‘good fuel housekeeping’ practices to ensure these challenges are controlled and prevented. These practices include purchasing good quality fuel, using a fuel polishing process and testing the fuel every 6 months. Furthermore, using a fuel polishing process (below) can prolong the usable life of fuel.
  • www.wasp-pfs.com The 7 Do’s and Don’ts of fuel housekeeping And of course, do not worry; help is at hand. Do Don't Ensure regular fuel polishing Ignore the problem Test/sample your fuel every few months Wait until you have an issue Integrate to your BMS (data is valuable) Use biocides without taking advise Audit your fuel supplier Assume you do not have biodiesel Ensure your engines are biodiesel ready Assume your in line filters will cope Read CONCAWE and similar information Ignore a fuel’s shelf life Speak to experts in the field Assume a generator test is a fuel test
  • www.wasp-pfs.com Fuel Polishing • Automated ‘good fuel housekeeping’ • Self pumping, self monitoring • Recirculation of fuel in storage tank sometimes referred to as ‘kidney loop’ or ‘dialysis’ • Removal of free and emulsified water • Particulate removal to 2 micron absolute Absolute filtration (100% of particulate) is finer than nominal filtration (over 50% of particulate) • Multiple stage filtration system • Integrate into building management system For feedback and cost saving measurements Fuel polishing is the innovative technological cleaning process used to remove water, bacterial infection, sludge, and solid and semi-solid contaminates from diesel and similar middle distillate fuels (gas and fuel oil, MDO etc).
  • www.wasp-pfs.com By polishing fuel every 2-4 weeks • Any water ingress is quickly found and removed • Any bacterial infection is removed • No build up of water, sludge or biomass • Removes of any potential requirement for additives • Removes chemical handling, H&S and REACH requirements • Maintains fuel in optimum condition and quality By preserving fuel quality • Massive potential saving in both carbon and monetary terms • No costs for disposal of old fuel • No costs for new fuel
  • www.wasp-pfs.com Severe Weather Brown Outs Network Failures Power Cuts Power Shortage Blackouts Maintenance Issues Think… The design of the fuel polishing system aims to maintain optimum fuel quality in diesel which is stored for the medium to long term, preventing the fuel from causing back-up generator failures during an emergency situation. With reports about the 4% slack in the system causing unplanned blackouts and power cuts, it is essential for organisations to start thinking about ensuring their generator is supported.
  • www.wasp-pfs.com Why is this the solution? • Reduces the risk of losing power during a crisis • Improve continuity, efficiency and resilience of your generator • Limits costs of exposure to fuel replacement • Avoids costs of disposing of fuel • Avoids losing ability to trade • Improves the reputation of the company • Reduces your carbon footprint • Saves money
