摘要：

The paper presents a review of methods to predict parachors of heptane-plus (C-7+) fractions and pseudocomponents. A quantative comparison is made of seven existing correlations and one proposed in this study using the Weinaug-Katz interfacial tension model. With the exception of one (based on critical volumes) which gave very poor predictions, all the correlations predicted the results with mean absolute deviations around 20-40%. The study has been limited in scope and is inconclusive because of the paucity of experimental data. However, it serves to illustrate the problems to be addressed in the future.
