Consideration for Character of Stability and Ignition for Marine Fuel Based on Infraved Spectrophotometry (I. R)

We, vessel operator face to much loss not only labor but also expense when have some obstruction, which are like as blockage of fuel filter by sludge, on the line of fuel pre-treatment system cause to inferior stability of Marine Fuel Oil including to mingle different kind of fuel each other. But at the present, there should be no way to determine the quantity simply except visual inspection such as a ‘Spot Test’ In consideration of above, we will introduce our new method to know a character of Marine Fuel stability from Asphaltene content value/Aromatic ingredients value ratio from a view of generating sludge factor. And a method to estimate the stability for mixture/heating with I. R data of individual fuel before heating. And also a method to estimate the Ignition character of Marine Heavy Fuel Oil with original calculated Diesel index instead of Aniline point.
