Crystallization in a supercooled liquid or a glass occurs via a nucleation-growth mechanism which starts by the formation of small ordered germs. The germination can be enhanced by the presence of rough interfaces in the melt. Figure 4 gives an example of nucleation and growth curves for a glass. Figure 4.

Crystallization is a process step in a vast range of applications and industries such as chemicals, API production, food manufacturing and precipitation of ores. Depending on the process requirements, cooling, evaporation or precipitation is selected to form crystals. Accordingly, the variation of applied machines is numerous.

Crystallization is an important unit in the pharmaceutical and fine chemical industries. For high performance control of crystallization, real time process data is required. Increasing attention needs to be given to crystal shape. Reliable shape information can be obtained exclusively from crystal images.

Crystallization is the process of forming solid material from a liquid solution or melt, where the solid material formed has crystalline (as opposed to amorphous) structure. A crystallization process generally has the following characteristics: ... For a more complete analysis of population balance and its application to crystallizers, refer to ...

Dec 29, 2021 The continuous MSMPR crystallization of ASA was monitored in-line using image analysis in this work. The MSMPR reactor had overflow tubing for the outlet flow, which provided a unique, novel approach for the in-line monitoring of the process. A steep glass plate was placed under the tube, and a high-speed process camera was mounted in front of it.

Feb 18, 2020 Crystallization process parameters and reactor configuration are directly influencing the particle size distribution of an active ingredient (Engstrom et al ). There are many parameters influencing the PSD, to which we need to add the scale-dependence of many of these parameters.

Further analysis indicates that the cubic particles were formed by the classic crystallization process via layer-wise deposition, while the dendritic particles were formed by the non-classic crystallization process through cluster aggregation. The control over the chemical diffusion prolongs the nucleation period and produces nuclei ...
