“…The design and simulation of solvent extraction processes have been done mostly by fully empirical methods [6]. This approach is limited because the experimental information is not usually available and a more rigorous model is needed to simulate changes in operating conditions or feed quality.…”

“…Three main methods have been presented for modeling of such mixtures namely pseudocomponent by Mukhopadhyay and Dongaonkar [9] and Rahman et al [12], continuous by Chorn and Mansoori [4] and Riazi [14], and making model molecules by Ruzicka et al [17]. The pseudocomponent method which is the oldest among the above mentioned methods, is suitable for those processes in which the characteristics of the individual molecules in the mixture are not of a great importance.…”

A method has been developed for the modeling of complex hydrocarbon mixtures which is based on the accurately simulated distillation gas chromatography analysis as well as the extended method of Ruzicka et al for making the model molecules. The method has been used for modeling of the complex mixture of the lube-oil cut SAE 10 in the aromatics extraction process with the solvent N-methylpyrrolidone (NMP) from the Tehran Refinery. To carry out the liquid-liquid equilibria calculations, the van der Waals surface and volume size parameters of the model molecules and NMP as well as their interaction parameters are required which they are calculated by the Bondi's group contribution method with the NMP molecule taken as a functional group according to the approach of Rahman et al. Solvent extraction process at two temperatures of 50 and 42 C both at 1 atm have been carried out in a batch mixer-settler and the properties of resultant phases (extract and raffinate) have been determined by the precise measuring systems using the standard methods of ASTM and the well-known Riazi's equations. Finally, the results of the equilibrium calculations have been compared with the experimental data and good agreement was found.
