Learning Objectives

The course introduces to the knowledge of the more widespread process industry plants and equipment (Unit Operations), providing the fundamental elements for the choice and the calculation of the main units used in the operations of phase separation and for their management. At the end of the course, the student will be able to correctly determine the specifications of the individual devices and to evaluate the effects of a variation of operating parameters on the performance of the process.
