    • Crystallization kinetics for the sucrose-water system were studied in a continuous MSMPR cooling crystallizer. Growth and nucleation rates were derived from the measured size distributions using the population balance equation. In the region of higher supersaturation, where secondary nucleation occurs, it appeared that growth was a linear function of supersaturation; whereas, nucleation was approximately 1. 5 order in supersaturation. Growth rates were lower for crystals smaller than about 60 mu m, although these too increased with supersaturation. The latter trends were observed in both the higher (nucleating) and lower (non-nucleating) supersaturation regions. Preliminary batch studies indicated that the rate of secondary nucleation was also a function of both the method of contact and the impact energy.

  • Characterization of solution structure near the surface of a growing crystal by Raman spectroscopy
  • 1984

  • Konferensbidrag (refereegranskat)abstract
    • In situ structure analyses of the supersaturated aqueous NaNO//3 solution near a growing NaNO//3 crystal have been performed using micro Raman spectroscopy. It was observed that the relative concentrations of higher ordered species (contact-ion pairs, and ion aggregates) are diminished near the growing crystal, indicating that these species are dominant in the diffusion process when compared to free aquated ions or solvent-separated ions. There were no detectable differences between the spectra obtained for saturated and supersaturated solutions.
