According to complex and undefined compounds in lube cuts, this complex material needs more
definition and specialization. In this paper, lube cut as a mixture of aromatic group and nonaromatic
groups (including paraffin and naphthene) is considered and each group considered as a
pseudo component. The results of the UNIQUAC (Universal QUAsi Chemical) and NRTL models
-applied in LLE system- by using numerical solution in different temperatures and different
volume ratios of solvent-to-feed is compared with the results of PNA method (RIAZI et al) based
on experimental data. There is a good agreement between the numerical method results and the
experimental data. The results of numerical method using UNIQUAC model are closer to the
experimental data in comparison with the results of numerical method using NRTL model.
Comparison values are include, equilibrium components weight or mole fractions, yield and other
parameter, in extract and raffinate phases.
