Title: Prediction of cloud point temperatures and amount of wax precipitation

Abstract

The paper presents a vapor-liquid-solid model for predicting phase equilibria of oil mixtures taking into account the possible formation of a wax phase. The gas and liquid phases are described using the Soave-Redlich-Kwong equation of state while the wax phase is assumed to be an ideal mixture. Only part of the heavy hydrocarbons are considered to be able to potentially enter into a wax phase. A procedure is developed for estimating the fraction of the heavy hydrocarbons which may potentially form wax. Calculation results agree very well with experimental wax precipitation data.
