The water solubility of crude oils and petroleum products

Abstract

Solubilities are reported for 42 crude oil and petroleum products in water as a function of temperature, salinity, oil weathering and water-to-oil volume ratio. The applicability of several analytical techniques (purge-and-trap gas chromatography, high pressure liquid chromatography, and fluorescence) for the determination of dissolved hydrocarbon concentrations is discussed critically. The effect of water-to-oil volume ratio on the apparent solubility of oils in water is discussed in detail.
