Our Bio-Fuel Scrubber is a Patent pending system designed to significantly reduce the maintenance cost and premature failure by removing alkali metals in the fuel stock prior to combustion in gas turbine engines.
The elimination of salt, calcium and other alkali metal substances in the fuel stock by the Bio-Fuel Scrubber significantly reduces and in many cases eliminates the high temperature corrosion and premature failure in gas turbine engine components caused by the hot section sulfidation process.
During combustion in the gas turbine, sulfur from the fuel reacts with sodium chloride from the air intake of sea air at elevated temperatures to form sodium sulfate. The sodium sulfate then deposits on the hot-section components, such as nozzle guide vanes and rotor blades, resulting in accelerated oxidation (or sulﬁdation) attack and premature failures. In some cases this accelerated oxidation can reduce the operational life of a gas turbine by more than 50%.
This accelerated oxidation is commonly referred to as “hot corrosion”. Sulfur in the fuel is generally limited to 0.3% for commercial jet engines, but can be as high as 1.0% for marine diesel or higher for bunker fuel used in marine gas turbines. Sodium chloride comes from seawater. Seawater is also an unwanted source of sulfur, this compounds the problems with higher pollution in the exhaust emissions.
The Bio-Fuel Scrubber is the most economical solution currently available. With a ROI (return on investment) of 6 to 9 months the Bio-Fuel Scrubber not only pays for it self in initial maintenance cost savings, which after ROI become significantly reduced operating cost. Those reduced operating cost translate into higher profit margins, in some cases equaling millions of dollars saved. Finally, the benefits are not limited to maintenance cost savings The Bio-Fuel Scrubber will reduce emissions and make meeting the 2020 IMO emission regulation standards more affordable and in turn more realistic for marine operators.
