- 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.

- The Lulea Image Processing System is presented. Some fundamental system design criteria are discussed together with some aspects of the actual implementation. The system is structured in two levels in form of a pseudo-overlay. The layout of the image Data File is recognized as an integral part of system architecture. A number of major processing tasks are discussed in detail
