AB  - This study described the solvent extraction of residual oil from filter cake sludge. This study was
conducted using soxhlet method with three different solvents, namely n-hexane, methanol and acetone. Prior
to that, the sample was dried at 105°C to obtain the profile of moisture content and optimum drying time. The
time consumed to dry the sample is 6 days and the moisture content is 64.12%. The oil extracts were analyzed
based on oil yield, pH value, antioxidant, FTIR and GCMS analysis. The result shows that the percentage of
oil extracted using methanol (yield 66.6%) is the highest compared to that of acetone and n-hexane. The
n-hexane extract is somewhat acidic. The FTIR and GCMS analysis suggested that the functional groups and
major components are mostly from the composition of fatty acids. The extraction was able to reduce the weight
of filter cake sludge for economical disposal and further studies would be needed to establish the useful
applications of the oil extracts.
