Abstract

The development of a technique of vanishing interfacial tension (VIT) was discussed. A parachor IFT model was used for determining the miscibility which was compared with the VIT experiments and equation of state (EOS) calculations. It was observed that interfacial tensions computed using the parachor model was differed from the experimental measurements by more than 1.0 dyn cm-1 when IFT was above 3 dyne cm-1. Analysis shows that the parachor computational model over-predicts minimum miscibility pressures when compared to VIT experiments (by about 4.5 MPa) and EOS calculations (by about 1.0 MPa0.
