Abstract
The high demand of road transport has forced the oil refining industry to
produce gasoline and diesel in greater quantities. Consequently large marine engines, which
employ Heavy Fuel Oil (HFO), a mixture of oil refinery residue blended with cutter stock, as a
fuel are receiving more carbon rich and higher aromatic content fuel causing serious problems
such as piston ring wear, cylinder liner scuffing, solid deposition, exhaust valve sticking. HFO
contains thousands of different components, hence classical thermodynamics modelling is
inadequate and an alternative approach such as continuous thermodynamics is required to
model multicomponent fuel. This paper outlines procedures for determining the chemical
composition of HFO by separating it into chemical fractions differing in chemical composition
and physical properties, and subsequent analysis. Sequential elution solvent chromatography
was used to separate HFO into Saturates, Aromatics, Resins and Asphaltenes. Gas
chromatographic analysis is insufficient to determine the overall composition of HFO, because
most of the heavy compounds are not sufficiently volatile. Subsequent mass spectrometric and
elemental analysis showed a wide range of molecular weight distributions for the fractions. The
results also indicate that the saturates fraction contains cyclic structures with aliphatic side
chains while the aromatics fraction contains tetracyclic aromatic rings with aliphatic side
chains.
