heal.abstract	Hydrocarbon fluids play an important role in today's society, being essential components of oil and fuels. Phase equilibria knowledge of such mixtures is important in designing equipment and processes. Among the least studied equilibriums is that between solid and liquid phases (SLE) which is required in, e.g., wax formation studies. Still, a number of models have been proposed for estimating the activity coefficient but are rarely investigated against SLE data. In this study, a number of 'well-established' and 'up-to- date sophisticated' activity coefficient models are tested for their capability in predicting solid-liquid equilibria of alkane systems. A large database covering 63 alkane/alkane systems for which SLE data are available is considered. The models include several of the popular approaches proposed during the past 30 years covering the gap of a comprehensive literature review. The capabilities and limitations of the models are discussed and those that provide successful predictions are recommended at various levels of accuracy and complexity.Hydrocarbon fluids play an important role in today's society, being essential components of oil and fuels.
