Evaluation of saturated liquid density prediction methods for pure refrigerants

Fourteen correlations and four equations of state (EOS) have been used to predict the liquid density of 15 refrigerants. Overall, Hankinson and Thomson correlation [R.W. Hankinson, G.H. Thomson, AIChE J., 26 (1979) 653–663] with an average of absolute percent deviation of 0.381 is the best for the prediction of liquid density of the refrigerants. The Chain of Rotator Group Contribution (CORGC) equation of state [J.D. Pults, R.A. Greenkorn, K.C. Chao, Chem. Eng. Sci., 44 (1989) 2553–2564] with an average of absolute percent deviation of 1.227 is the best among the equations of state and the fourth in overall.
