Water-in-oil emulsions of Athabasca bitumen diluted with toluene have been studied using the latest advances in acoustic and electroacoustic spectroscopy. From the sound attenuation spectra of emulsions, the water droplet size distribution is measured. ...
It is shown that acoustic spectroscopy can sense the presence of a small sub-population of large particles in a concentrated dispersion of much smaller particles. ...
An ultrasound pulse interacts with dispersed particles while propagating through the dispersed system, thereby attenuating. An acoustic spectrometer measures this attenuation for a set of frequencies and calculates the corresponding particle size. ...
This distribution is asymmetrical on the logarithmic scale of particle sizes.The modified log-normal distribution is especially useful for acoustic spectroscopy because sound attenuation is very sensitive to the presence of large particles. ...
