The design of crystallization processes becomes more complicated when mixing affects the final crystal product quality (e.g., crystal size distribution and polymorphic form). Such mixing effects are more apparent in antisolvent and reactive crystallizations, which involve the blending of different fluids, and in large-scale crystallizers, where homogeneity cannot be easily achieved. In this pap...

Our research on knowledge management is rooted in the community perspective. We believe that knowledge systems should serve primarily to help people create and share new knowledge. But we also acknowledge the role of stable, structured and reliable information, both as a component of our systems and as a component of the organizations within which we work. The contribution of the paper is a fra...

The growth kinetics of calcite crystals are studied in a batch-fluidized-bed crystallizer, which is maintained at a constant pH. The growth experiments are conducted in the metastable region explored as part of this research. The crystal growth rates are e®aluated from the consumption rates of calcium ions, using the cured natural calcite or silica sand as seeding materials. Se®eral operation ®...

−To obtain highly purified naphthalene, a column crystallizer was employed and operated in the continuous multistage countercurrent fractional mode. The principles and characteristics of the process are introduced. A large amount of experimental work has been done on the crystallization process in a D=50 mm×1,350 mm column. The effects of operation conditions including the composition of feed, ...
