Introduction. Spherical crystallization is a particle design technique in which crystallization and agglomeration occur simultaneously, yielding agglomerated crystals in a spherical shape, and has been established as a useful process intensification route that consolidates crystallization, milling and granulation. Kawashima et al. 1982, Kumar et. Furthermore, form I exhibits low polymorph stability. To solve these problems, spherical crystallization technologies were developed for the two shapes. For form I, the mechanism was studied and found to involve D-nucleation and spherulitic crystal growth. In the case of form II, the spherical crystallization process was based on agglomeration. Membrane crystallization MCr, which has made significant progress in recent years, is a hybrid technology platform with great potential to achieve this goal. This review illustrates the basic concepts of MCr and its promising applications for crystallization control and process intensification, including a state-of-the-art overview of microscale crystallization located at the frontier of chemical engineering, materials science and biochemical research and influenced by many factors . The precise regulation and control of crystal processes on a microscale is still a major challenge. In the heterogeneous induced nucleation process, the chemical and micro-nanostructural features of the, associated with hotspots, the safety and energy performance of EMs could be well balanced by crystallization. 1 Introduction. Energetic materials EMs are widely used in the civilian and military sectors. Many drugs have a tendency to agglomerate, resulting in poor fluidity. Spherical crystallization can be used to improve product properties including flowability and particle size. In this work, two: The semi-continuous anti-solvent crystallization process of pyraclostrobin was investigated using an integrated microfluidic device that includes both microfluidic channels and an agitated crystallizer. We successfully controlled the crystal morphology as quasispherical particles and reduced the particle size distribution in comparison. A highly controllable and efficient crystallization process is the urgent requirement for a hyperpure solid product and the green process technology. In particular, the precise regulation of microscale nucleation and crystal growth intensification is a multidisciplinary and multiscale topic that has attracted the attention of many researchers. Resume. Crystallization is a fundamental separation technology used for the production of solid particles. Accurate nucleation and growth process control are vital, but difficult. A new control technology that can simultaneously intensify the overall crystallization process remains a significant challenge. Recently, melt crystallization has emerged as an effective strategy for multiple applications in crystal engineering,. 2003.
