  4. Abstract:
  5. In this paper, the soave-Redlich-Kwong (SRK) Eos is modified based on perturbation theory. The parameter of the new cubic equation of state considered reduced temperature and a centric factor dependent. The average of absolute deviations of predicted vapor pressure, vapor volume and saturated liquid density of 30 pure compounds are 0.814.2.G14 and 5.814%, respectively. Also comparison with the new equation of vaporization of pure compounds are given. The florry-Hugines (FH) model is similarly modified by an adjustable parameter. This parameter is defined based on molecular weight of asphaltene to molecular weight of heavy oil ratio in form of polynomial function. The phase behavior of asphaltene was extended by these modifications and the precipitation of asphaltene is calculated by three n-alkanes solvents. The comparison between results is shown. The new model relatively accurate for predicting phase behavior of asphaltene in heavy oil. Copyright 2004, Society of Petroleum Engineers Inc
