A multi-component evaporation model to determine the onset of crude oil emulsification in seawater

Jennifer Anne Cragan, University of Rhode Island

Abstract

Once crude oil is spilled in an aquatic environment, its emulsification state becomes a key property in combating the spill. The onset of emulsification has been hypothesized to be due to decreases in the solvent strength of bulk crude oil. To better predict when emulsification will occur, compound-specific evaporation model was developed for crude oil spilled on surface seawater. A preliminary comparison between the proposed approach and common practice in oil spill modeling suggests that the component specific approach better tracks the evolution of bulk crude oil properties and composition, thus providing a method for determining when and if spilled oil will form an emulsion. Results indicate that the evaporative flux method proposed agreed well with published literature values.^
