Interfacial tension is the force that holds the surface of a particular phase together and is normally measured in dynes/cm. The surface tension between gas and crude oil ranges from near zero to approximately 34 dynes/cm. It is a function of pressure, temperature, and the composition of each phase. Ver mais Two forms of correlations for calculating gas/oil surface tension have been developed. 1. The first form is a pseudocompositional … Ver mais In 1973, Rameyproposed a pseudocompositional method for calculating surface tension. The two components are oil and gas. Gas is free to dissolve in the oil … Ver mais Use this section to list papers in OnePetro that a reader who wants to learn more should definitely read Ver mais The surface tension of a water-hydrocarbon system varies from approximately 72 dynes/cm for water/gas systems to 20 to 40 dynes/cm for water/oil systems at … Ver mais WebInterfacial tension (IFT) arises from differences between the intermolecular forces at the two liquid surfaces in contact with each other. …Therefore, the surface has excess Gibbs energy relative to the interior of the liquid. Surface tension is the excess energy per unit area (force per unit length; SI unit is Nm-1).
