Dr. Bing Han is currently working as a Post-Doctoral Researcher in the Department of Chemical Engineering, , Finland. His research interests includes As a solid-liquid separation technology, crystallization is a much more difficult and complicate process compared to other chemical unit operations. Crystal properties, quality and particle size of the product depend on operational conditions. Various crystallization processes such as reactive crystallization and anti-solvent crystallization are studied in the present research work. The target is to fully understand the fundamental and utilization of crystallization, and find out a proper method to control particle size distribution, especially for three phase system. Gas-liquid mass transfer of absorption in the presence of solid particles in a stirred tank is investigated in order to know how different-sized particles interact with gas bubbles. By using experimental and modern analytical methods, precipitation kinetics, mechanism and mass transfer of magnesium carbonate hydrates from a reaction of magnesium hydroxide and CO2 were systematically investigated. It can give greater insight on gas-liquid-solid reaction principle and mechanism from this heterogeneous crystallization. And new research approach developed can provide theoretical guidance and useful reference to promote development of gas-liquid reactive crystallization. Moreover, solubility prediction model by Pitzer thermodynamic model is investigated based on solubility measurements of potassium dihydrogen phosphate in non-electronic solutions. It not only fills the gaps in the literature data but also shows an easy and economic way to choose solvent in anti-solvent precipitation..
