Abstract
Calcination is the last process step of the sulphate method for production of titanium dioxide. The chemical reactions that occur during calcination are analysed by means of simultaneous DTA-TG-MS-measurements in order to provide a 5-step reaction schematic. The corresponding enthalpies of reaction are determined calorimetrically by means of the reversed drop method. The developed schematic is suitable for process modelling purposes.
Research highlights▶ Calcination step of sulphate process for production of titanium dioxide considered. ▶ Calcination of samples monitored by simultaneous DTA-TG-MS-measurements. ▶ 5-step reaction schematic identified. ▶ Enthalpies of calcination reactions determined calorimetrically.
