Crystallization

Crystallization is an operation widely spread in the industry.

It concerns an important variety of products : pharmaceutical, farm-produce, chemical…

However, this operation remains delicate to run.

Proposed run aims to make sensitive the student in various parameters and variable occurring

in the application of a crystallization.

This study will allow, from material and thermal balances, to end on this unit operation

of the Chemical Processing.

 

Parameters influence

Temperature, stirring speed, concentration

Feeding flow rate influence
