Welcome to Lab of Crystallization and Bioprocess 

Crystallization is a separation, purification, or finishing step which is required in many industries. There found in many industries, and our research focus on the application of crystallization in sugar industry (e.g., crystallization of sucrose), dairy industry (e.g., crystallization of lactose), and biopharmaceutical industries (e.g. crystallization of amino acids and proteins), etc. 

Bioprocess is any process that uses living cells to produce a product. Our research focus on the using the science and engineering for planning, designing, controlling, and building of biological processes to produce biochemicals (e.g., amino acids, sugar).

Our laboratory belongs to School of Chemical Engineering, Suranaree University of Technology, Thailand.
