Abstract: | Twu, C.H., 1984. An internally consistent correlation for predicting the critical properties and molecular weights of petroleum and coal-tar liquids. Fluid Phase Equilibria, 16: 137–150.The objective of this work was to use normal boiling points and specific gravities to develop simple but reliable and accurate methods for predicting the critical properties and molecular weights of petroleum and coal-tar liquids. The normal boiling points of the systems investigated range up to 1778 R and the specific gravities up to 1.436. This virtually covers the entire range of practical interest. The predictions of critical properties based on the above data show significant improvement over published correlations. |
