Abstract

In situ ultrasonic attenuation spectroscopy is used to examine the batch crystallization of urea from supersaturated aqueous and methanolic solutions. Benchmarking studies carried out on three cases are presented: noncrystallizing milled urea crystals in sunflower oil suspension, crystallizing pure urea from aqueous solution, and crystallizing urea in the presence of biuret habit modifier from methanol solution. In all cases, the technique was found to be capable of monitoring the size and concentration of anisotropic urea particles and it was responsive to the length and width of the needle-shaped crystals up to its upper size limit of 1000 µm. From measurements of changing particle size and concentration during crystallization, mass and linear crystal growth rates were calculated.
