Simulation and experimental evaluation of seed and supersaturation control design approaches for crystallisation processes
conference contribution
posted on 2013-01-16, 14:13 authored by Erum Aamir, Zoltan NagyZoltan Nagy, Chris RiellyChris RiellyThe paper presents a methodology for the systematic design of operating recipes for
batch cooling crystallisation systems with the aim to produce a desired target crystal
size distribution. The population balance model is solved using the method of
characteristics under the assumptions of a constant supersaturation and growth
dominated process, yielding a simplified analytical expression for the size distribution.
A method is proposed for designing the seed distribution, which can be used in
conjunction with the supersaturation set-point design to shape the product crystal size
distribution (CSD). The approach designs the seed as a mixture of crystals obtained
from standard sieve analysis. A second approach is also proposed which uses dynamic
seed addition during the batch to control the final size distribution.
