Aluminum and Silicon determination in bunker marine fuel

 

Aluminum and Silicon determination in bunker marine fuel

Engines manufactures recommend controlling Si (Silicon) and Al (Aluminum) content in residual marine fuel. Increased Si and Al content indicates catalyst particles presence in fuel, which may lead to abrasive wear-out of engine parts.

Si (Silicon) and Al (Aluminum) content is specified in ISO 8217:2010. From 25 to 60 mg/kg total Al and Si are permitted in marine fuel dependent on its type.

X-ray fluorescence method provides Al and Si content determination with minimum sample preparation. Definite mass of sample material is filtrated through filter (membrane filter with pores diameter  n*0,1 micron). To improve filtration the sample material may be diluted by hydrocarbon solvent. Catalyst particles stay on the filter; the filter is dried and analyzed. The obtained amount of Al and Si is divided by the sample mass (in g), so Al and Si concentration is obtained.

The method sensitivity is the first tenth parts of microgram per filter. So 2 grams of the sample material is sufficient for two concurrent measurements.
SPECTROSCAN МАКС-GVM

"SPECTROSCAN MAKC-GVM" WDXRF spectrometer determines elements from Na (Sodium) to U (Uranium) in solids, liquids or powders, in solutions and thin films, deposits on filters.
