For the past few years, the refining industry has limited its focus on interfacial problems to corrosion and emulations. Interfacial Properties of Petroleum Products covers all aspects of interfacial problems, discussing the properties of crude oils and petroleum products at the oil/metal, oil/water, and oil/gas interfaces that lead to rust, corrosion, stable emulsions, and foaming. This book provides an understanding of the effects of surface active molecules, trace contaminants, processing, and the use of surface active additives. It also addresses such topics as air entrainment and ion-exchange resin treatment, which has the potential to improve stabilities and interfacial properties.
