Abstract:Herein, the hybrid control mechanism of the crystal morphology modification for the treatment of a classic industrial ternary solution system (NaCl-EG-H2O) via membrane assisted crystallization was demonstrated. Solution concentration and component diffusion played the hybrid role on determining the polymorphic outcome of the crystal products. Metastable zone width under various operation temperatures and solution composition was simulated and validated by experimental results. The impact of the dominating growth mechanism (diffusion controlled growth or polynuclear growth) on the crystal morphology was also investigated. An optimized operation route aimed to simultaneously improve the crystal morphology and the separation effect was then developed based on the hybrid control mechanism. The solvent loss decreased from 4.8 to 1.2 wt%. Benefitting from the improved crystal morphology, the operative duration of corresponding downstream was also shortened. Advanced membrane assisted crystallization is a promising technology toward targeted crystal morphology for high-end solid products.
