The effect of stirring speed and reactant residence time in the bench scales CSTR on the reaction conversion of ZBS

The bench scales continuous stirred tank reactor (CSTR) for the synthesis of zirconium basic sulfate (ZBS) is one of the prototypes of research and development for the manufacture of nuclear-grade zirconium products in Center for Accelerator Science and Technology (CAST). The use of bench scale CSTR...
