Measuring Fines Precipitation to Improve Solid/Liquid Separations

Poor filtration and bulk density are often related to the number of fine particles present in a system. Inline particle size and count measurements identify the exact moment and conditions when fine particle formation occurs. By pinpointing the source of the inconsistency, the root cause can be identified, and a smarter process may be developed with improved solid/ liquid separations.

In a recent study of sugar crystallization, the effects of dissolved product concentration (supersaturation), pressure, and mixing efficiency on the number of fine particles (in the range 0.5-5μm) were measured over time. By leveraging immediate feedback researchers minimize undesirable nucleation events and eliminate filtration bottlenecks during laboratory development and in manufacturing.

Process variability is eliminated by quickly optimizing the concentration and minimizing nucleation. By understanding the particle size distribution in real time engineers eliminate yield losses and avoid downstream bottlenecks caused by excessive fines in the centrifuges, filters and dryers (dust).
