Title: DEPLETION OF WATER FROM OIL USING MAGNETIC HYDROPHILIC NANOPARTICLES
Abstract:
A method of removing water from oil comprising contacting the oil with hydrophilic paramagnetic or super-paramagnetic nanoparticles so as to provide water depleted oil is provided. The hydrophilic nature of the nanoparticles may be due at least in part to a coating of hydrophilic polymer. The method allows for depleting the water content in the oil to below 1 wt% water content. The method is suitable for oil-water emulsions, oil comprising a water layer, oil containing water droplets or containing only dissolved water.
