Abstract EN
The precipitation of wax/solid paraffin during production, transportation, and processing of crude oil is a serious problem.
It is essential to have a reliable model to predict the wax appearance temperature and the amount of solid precipitated at different conditions.
This paper presents a work to predict the solid precipitation based on solid-liquid equilibrium with regular solution-molecular thermodynamic theory and characterization of the crude oil plus fraction.
Due to the differences of solubility characteristics between solid and liquid phase, the solubility parameters of liquid and solid phase are calculated by a modified model.
The heat capacity change between solid and liquid phase is considered and estimated in the thermodynamic model.
An activity coefficient based thermodynamic method combined with two characteristic methods to calculate wax precipitation in crude oil, especially heavy oil, has been tested with experimental data.
The results show that the wax appearance temperature and the amount of weight precipitated can be predicted well with the experimental data.
