Abstract
A system for quantifying the petroleum content of aqueous media includes a sample cell; a first light source for generating a first light signal that stimulates fluorescent emissions when the first light signal irradiates hydrocarbons present in an aqueous solution in the sample cell; a spectral detector for generating a first electrical signal that represents spectral components of the fluorescent emissions in response to detecting the fluorescent emissions that are emitted from the sample cell; a second light source for generating a coherent light signal that is transformed into scattered light signals when the coherent light irradiates oil droplets in the aqueous solution; a detector for generating a second electrical signal in response to detecting scattered light signals emitted from the tube, where the second electrical signal represents the intensities and scatter angles of the scattered light signals; and a processor for determining a particle size distribution of the oil droplets from the second electrical signal and the hydrocarbon content of the aqueous solution from the first electrical signal and the particle size distribution.
