| Popis: | This paper (Part 2 of 2) revises and expands on the original model for the laminar flow continuous settling crystalliser presented in Part 1 in an effort to understand why the original model over-predicted product particle d 10 and d 50 and under-predicted the span and d 90 . Because agglomerates were observed experimentally, an agglomeration term was added to the initial theoretical model resulting in no significant particle size distribution prediction changes. On further analysing potential flow conditions a region of high flow and a subsequent area of low flow explained the d 50 and span deviations found experimentally. It was concluded that the difference between the ideal predicted spans and the experimental spans was due to non-ideal laminar flow conditions existing in the column. Although not achieved experimentally, it is postulated that an ideal parabolic laminar column flow profile would result in a narrow particle size distribution. |
