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.
