Abstract

The influence of interfacial tension between oil and water on permeation and rejection of oil drops during produced water treatment using a slotted pore metallic membrane has been evaluated. It was found that the rejection and permeation of oil drops through the membrane had a direct link with the interfacial tension experimentally and analytically. Oil/water emulsion with a range of interfacial tension (4 and 30 mN/m) were tested experimentally and analytically and a comprehensive set of data is presented. The higher interfacial tension between oil and water phases provided better rejection and lower permeation through the slots. The oil drops were assumed to be passing through slots by the drag force generated by the flow of the fluid passing around the drops. While the other force referred to as the static force tried to restore the spherical shape of the drops and plays an important role in the rejection of drops. The static force had a direct association with the interfacial tension. The drag force and the static force counter each other at every stage. The higher the drag force than the static force cause permeation of the drops, while, in the case of a higher static force than the drag force, rejection of drops was dominant.
