碩士 === 國防大學理工學院 === 化學工程碩士班 === 101 === Purity control is a key factor in industrial application, and crystallization is one of technologies with purified separation. To investigate the variation of operation relation, has important implication for crystal purification effect. Therefore, controlling to make higher purity, better polymorphs and crystal size distribution procedure, has play an important role. In this study, using 1,3,5-Trinitroperhydro -1,3,5-triazine (RDX) be the object, with crystallization property and operation condition in the crystallization. To product the impact of demand range with produce, using dynamic method explore the process of population balance, nucleation rate and interference mechanism with experimental variables. The nucleation and growth rate of RDX expression the results in a particle size from zero has significantly different rate. And in the effective diameter 64μm, with a rate of B = 13885.23σ-0.09Mt11.42C12.02, and G =2.25x10-8σ0.10C-2.15. With the mechanism of crystal, it appears lower additives supersaturation increase from with particle size decrease, and a high degree decreased then with the amount increases.
