PEES8AA REACTOR SYSTEME ANALYSIS

PEES8AA

Reactor System Analysis

ECTS Credits : 2

Duration : 21 hours

Semester : S8

Person(s) in charge :

Fabrice PATISSON, Professor, fabrice.patisson@mines-nancy.univ-lorraine.fr  

Keywords :  Systemic approach, reactors, heat exchangers, process engineering, chemical kinetics, transfers

Prerequisites :  Transport phenomena

Objective: To become familiar with the systemic approach to reactor and heat exchanger modelling .

The goals of this course are to illustrate the way energy, process and environment interact, to give the theoretical tools to size reactors and to calculate their matter and energy balances. This course builds the methodological bridge between the SP131 "Transport phenomena" and SP145 "Environmental Impact Assessment". After introducing the systemic approach in process engineering, it will be applied to determine the working parameters of reactors and exchangers used for energy production in the industry, before moving on to the assessment of their environment impact.

Progress : - Course presentation. Goals. Systemic analysis. Reactor classification. Energy hungry and/or CO₂ emitting industrial processes : examples. Ideal reactors. (1) Chemical kinetics revision class. Matter balance in a transient state closed reactors. (2) Matter balance in perfectly mixed reactors and steady-state pistons. Associating reactors. (3) Energy balance in ideal reactors. - Heat exchangers. (1) Inter phase transfers. Simplified theory of matter exchangers, closed and open. (2) Simultaneous heat and matter exchanges. Humid air processing.

Complementary conference : CO₂ sequestration processes for industrial energy production.
