ABSTRACT

Interfacial tension is an important property for many processes such as enhanced oil recovery by gas injection and flow through porous media, and in mass and heat transfer applications. The objective of this study is to study four prevalent interfacial tension models along with their governing mechanisms. Also, Mechanistic Parachor model has been studied in comparison with Parachor Model. The trait of the Mechanistic Parachor model is that it considers the mass transfer mechanism responsible for attaining the thermodynamic fluid phase equilibria in multi component hydrocarbon systems, while the other three IFT models doesn’t consider the effect. The Mechanistic Parachor model has been tested on Rainbow Keg River (RKR) crude oil-gas systems and showed better IFT prediction over the conventional Parachor model.

Key words: Interfacial Tension, Parachor Model, Mechanistic Parachor Model, Gradient Theory.
