“…As expected, the MSZW decreases with an increase in the mixing intensity. [40][41][42][43] Additionally, Ni and Liao 10 also described a similar trend for the crystallization of L-glutamic acid in an OBC. 9 As with the results in Fig.…”

This work aims to show the viability of applying video imaging techniques to the cooling crystallization of paracetamol in an oscillatory baffled crystallizer for the determination of the metastable zone width and crystal size distribution. From these data, the effects of supersaturation and mixing on metastable zone width and mean particle size are examined. Both sets of data are in good agreement with previous studies in a stirred tank and oscillatory baffled crystallizers. Finally, utilizing the Kubota's interpretation of metastable zone width, we demonstrated that the video imaging techniques are as sensitive to nucleation events as FBRM probes

“…The development of nuclei which refer to the influential of microscopic crystals in the magma is the phenomenon of secondary nucleation [15]. This nucleation happens when the crystal growth is introduced with a contact of other existing crystal or "seeds" [16].…”

Nucleation is one of the processes that involves at the beginning of the certain process like freezing, melting, boiling, condensation and crystallization. This process normally occurs in the industry, where it is involving the thermodynamic phase that involves work, energy and temperature. The nuclei growth happens when the initial phase changes to the other phase. Unfortunately, the detail for the theory of nucleation is not well-known around the people who are working in the industry, even though there are many reports or writings available. Thus, few types of nucleation like homogeneous and heterogeneous nucleation and the other theory of nucleation have been summarized in this chapter.

“…The most reliable and accurate procedure appears to be that, suggested by Chianese et al (1993), based on the performance of batch seeded crystallization runs under very low supersaturation. This latter condition is required to assure that i) the fines are originated only by fragments, since primary nucleation in the solution bulk is negligible; ii) the size distribution of fines is not greatly affected by crystal growth, thus being representative of the size distribution of the generated fragments.…”

The present work reports the results Or50 called "impact experiments" on nine different kinds of crystals, five inorganic salts and four organic acids, performed by letting ten crystals fall through an evacuated tube onto a glass plate. The ratio between the abraded volume ofa crystal and the volume ofthecrystal itselfis inversely proportional to the plasticity index of the material. The size distribution of the fragments, in terms of number density function vs. size, is well fitted for all the systems by a power law equation with an order equal to -2.82.For one of the system examined, potassium sulphate, the size distributions of fragments obtained by the impact experiments have been successfully compared with those of the fines produced during batch seeded crystallizations carried out at low supersaturations. It therefore appears that the size distribution of the fragments generated by crystal attrition in a crystallizer may be generally predicted by means of the proposed power law equation.
