CRYSTALLIZATION
82328. 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 is simply a very fast, perhaps uncontrolled, crystallization process. For others it is crystal formation resulting from a chemical reaction. It can also vary by industry; in the pharmaceutical industry “crystallization” is common and in the chemical industry “precipitation” is the vernacular.A Guide to Effective Crystallization Process Development

Crystal-size distribution-based dynamic process modelling,
The industrial crystallization process development has been acknowledged in the literature as one of the most challenging with respect to optimization and scale-up, as it depends on the complex interplay of several thermodynamic and scale-dependent kinetic, transport, and hydrodynamic phenomena in a heterogeneous system Crystallization is an extremely old unit operation, but is still used to produce highly specified speciality chemicals, and pharmaceuticals. In fact, there are few branches of the chemical and process industries that do not, at some stage, employ crystallization or precipitation for production or separation purposes (Mullin, 2003).Industrial crystallization in practice: from process to product

Organic crystallization processes ScienceDirect
Nucleation. Growth. 1. Introduction. Crystallization has been arguably the most important separation and purification process operation in the pharmaceutical industry throughout its history. Many parallels exist in the fine chemicals industry as well. In the past one to two decades, the study of crystallizer operation has taken on even higherProcess Quality. Crystallization also influences process quality, such as drying, flowability and scalability. For example, a wide particle size distribution of the API crystallization process could cause slow filtration and inefficient drying, thus creating a bottleneck in the entire manufacturing process.Crystallization & Precipitation Definition, Steps, Equipment

Systematic Investigations on Continuous Fluidized Bed Crystallization
Recently, continuous crystallization has again become the focus of many research activities. Efforts have been made to develop design rules based on comparing it with the corresponding batch process [1,2] or to elucidate basic mechanisms, for example, the impurity incorporation and carryover [].Additionally, novel concepts, applying to The effect of ultrasonic time (from 1 to 9 h at an interval of 1 h) on L-glutamic acid crystallization was studied. The effects of stirring speed (120, 160, 180, 200, and 220 rpm) and acid adding rate (0.1, 0.5, 1.0, and 1.5 mL/min) on L-glutamic acid crystallization were determined.

Recrystallization Guide: Process, Procedure, Solvents METTLER
Recrystallization is a technique used to purify solid compounds by dissolving them in a hot solvent and allowing the solution to cool. During this process, the compound forms pure crystals as the solvent cools, while impurities are excluded. The crystals are then collected, washed, and dried, resulting in a purified so.Crystallization is the main thermal process resulting in the formation of solid products and, therefore, is widely spread in all kinds of industries, from fine chemicals to foods and drugs. For these high-performance products, a quality by design (QbD) approach is applied to maintain high product purity and steady product parameters.
