The CatGuardTM system uses state-of-the-art Nuclear Magnetic Resonance (NMR) technology to
measure catfines in heavy fuel oil (HFO). Cat fines are zeolite-type aluminosilicates that,
when present in the fuel oil, cause abrasive wear of engine system parts, ultimately leading
to costly engine breakdown. Since silicon posesses lower sensitivity for NMR analysis than
aluminium, the CatGuardTM system measures the aluminium content of the HFO, and use silicon
modelling in order to obtain the total catfines level. Silicon modelling is based on the
aluminium to silicon ratio found from a NanoNord study of 248.000 paired Si/Al laboratory
measurements of HFO.
