Abstract

The present work consists of the study of the intensification of the processes of crystallization and precipitation, through the use of intensifying energy generated by ultrasound. The intention is to study the systems of crystallization by cooling of solutions in batches and of chemical precipitation in solution operating in semi-continuous regime. We will evaluate the parameters of the crystallization and precipitation: nucleation, growth and aggregation, when the systems are subjected to different intensities of energy generated by ultrasound.
