The influence of barium sulphate crystallization parameters on its crystals size

Matynia A., Wlazło P., Koralewska J.

Polish Journal of Chemical Technology

2001

Vol. 3, nr 1

15-20

The research results of barium sulphate crystallization from barium chloride solutions are presented. Barium sulphate was precipitated in the continuous crystallizer with the internal circulation of suspension fed with crystalline ammonium sulphate. The influence of barium chloride concentration in feeding solution, residence time and the temperature on barium sulphate crystals size and growth rate were determined. The advantage of the research results and elaborated relations may be utilised in the post quenching salts treatment process.
