Nomogram for Deriving CCAI A straight line connecting the viscosity and density of a fuel oil gives the CCAI, which can be used to rank ignition performance. High CCAI (845-865) (Calculated Carbon Aromaticity Index) Aderco additives break down the agglomerations and disperse the asphaltenes in the bulk of the fuel, thereby improving combustion and producing less soot. Aderco additives reduce exhaust gas temperature by 30ºC. High Instability / Incompatibility Aderco additives are strong surfactants which homogenize unstable fuels and resolubilize precipitated asphaltenes, thereby restoring centrifuge operations to normal values and cleaning cycles. This operation is performed in less than 8 hours. High Vanadium The dispersant action of Aderco additives enhances combustion and reduces soot to a minimum, resulting in the complete elimination of vanadium in the exhaust system without deposits or corrosion. Clean Tanks Aderco additives disperse and regenerate the sludge formation slowly and safely into burnable fuel, protecting tank interiors, piping and other components against corrosion. No more expensive tank cleaning required, and, more specifically, no more costly sludge to dispose of. In many ports sludge disposal is increasingly regulated and expensive. Clean Filters / Pre-heaters Reduced deposits and less maintenance of the fuel pre-heaters mean better heat transfer and a more efficient operation. Reduced cleaning frequency requirements for the filter elements translates into longer filter element life, especially in the very sensitive back flush filters elements. HFO without Aderco shows large agglomerations. Same HFO with Aderco shows that large agglomerations have disappeared and particles are finely dispersed. Without Aderco With Aderco Deposit on Injection Nozzle Clean Centrifuges Since Aderco additives homogenize the fuel and disperse the sediments, centrifuge overload disappears and throughput returns to normal with minimum dry sludge rejects. With this smoother operation, cleaning intervals are significantly lengthened. Supervised tests have demonstrated savings, through reduced dry sludge rejects with treated fuel, sufficient to cover the cost of these additives. There is 40% less sludge production with Aderco additives. Clean Injectors Aderco additives prevent both needle sticking and trumpet formations on injector nozzles. The result is a fine mist of symmetrically distributed droplets ensuring complete and efficient combustion. The quantity of droplets is increased by 30%. Clean Combustion chamber Aderco additives reduce the risk of cylinder coverhead cracks. Keep nozzles free from carbon build-up and maintain extremely clean piston and crown surface. Rings are Free Aderco additives keep ring backside carbon free, maintain ring elasticity and help minimize ring and liner wear. Clean Scavage area and stuffing boxes Aderco additives drastically reduce carbon deposit and minimize the risk of fire. Clean Exhaust valves As already mentioned, without formation of unburned solids, deposit accumulations in exhaust valve cages and on valve stems and seats are minimal. High temperature corrosion is not a factor, blow-by will be eliminated and time between overhaul (TBO) can usually be extended by more than 30%, depending on the quality of fuel used. Clean Turbo-chargers Better combustion with no unburned solids means clean and efficient turbo-chargers with no high temperature corrosion. Aderco additives prevent surging. Clean Exhaust gas boilers The clean exhaust gases, as we have seen in the turbo-chargers, also mean clean and more efficient exhaust gas boilers providing better heat transfer and extended TBOs. Aderco prevents the risk of fire! Clean Funnel With increasing environmental concerns, the much cleaner funnel provided by Aderco additives is a major advantage. The reduction of sparks and carbon fallouts represents essential environmental improvements. Particulate emissions are reduced by 25%.
