The formation of wax crystals in petroleum fluids, due to decreasing in solubility of the heavy hydrocarbon components causes serious operational problems in the oil industry. A predictive approach to calculating the wax crystallization would help to control the deposition. The objective of this paper is to develop a thermodynamic model that is capable of predicting wax precipitation. The regular solution theory has been modified for the solid – liquid equilibrium modeling. The results are presented and compared to the reported experimental deposition data. It is shown that the model prediction is in an excellent agreement with these data.
