Reacting systems - 3FME1027

Goal(s)

Learning outcomes :

• To understand a simple total or balanced chemical reaction based on the basic elements of apparent velocity laws (Kinetic laws; Reaction speed; Mechanisms; Progress rate...)
• To write material balances with reaction and energy transfer
• To size homogeneous chemical reactors, ideal isothermal or non-isothermal (volume, flow, temperature action, operating stability, etc.) based on reactor positions and classifications, balances (materials and energy) as well as knowledge of applied fluid mechanics (flow, agitation, etc.) and mathematical tools (solving simple differential equations);
• To determine the potential performance of reactors (selectivity, efficiency,...), and choose or even combine them, according to criteria (volume; kinetics; single, multiple series or parallel reactions);
• To characterize and model real reactors from ideal reactors by integrating the problems related to their implementation (Distribution of Residence Time,...)
