Removal of crude oil from kaolinite by water flushing at varying salinity and pH

Fogden, Andrew


The ability of crude oil to adhere to kaolinite in an aqueous environment by adsorbing or depositing its polar components (asphaltenes and resins), and the ability of subsequent water flushing to remove this bound oil, were compared for two oils and varying salinity and pH of the flushing solution. A scanning electron microscopy technique was used to image the locations of oil residues on and between kaolinite platelets, while fluorescence spectroscopy yielded the corresponding amount of...[Show more]
