چکیده

Crystallization is a key unit operation that finds extensive applications in pharmaceutical, food and fine chemicals industries . The operating conditions of the crystallization process have a direct effect on the purity, size distribution, shape and polymorphic form of the crystals. These properties in turn affect the efficiencies of the downstream operations such as filtration, drying and formulating, and product effectiveness such as dissolution rate, bio-availability and toxicity . Therefore, batchto-batch uniformity of the crystal properties is important from a consumer and regulatory point of view .

Mathematical modeling and fuzzy availability analysis for serial processes in the crystallization system of a sugar plant

The binary states, i.e., success or failed state assumptions used in conventional reliability are inappropriate for reliability analysis of complex industrial systems due to lack of sufficient probabilistic information. For large complex systems, the uncertainty of each individual parameter enhances the uncertainty of the system reliability. In this paper, the concept of fuzzy reliability...

Particle Size and Shape Control in Crystallization Processes

Crystallization from solution is an industrially important unit operation due to its ability to provide high purity separations. The control of the crystal size distribution can be critically important for efficient downstream operations such as filtration and drying, and product effectiveness (e.g., bioavailability, tablet stability). This paper provides an overview on recent developments in t...
