Advanced Chemical Reactors
This course assumes prior knowledge and understanding of chemical reaction kinetics and chemical reactors design, operation and control. It covers the details and irreversibilities found in real life chemical reactors due to the nature of design, mass and heat transfer and competing phenomena within the ‘ideal’ vessels. Transport phenomena, kinetics, thermodynamics, computational chemistry and CFD simulation are used to accurately represent the real life environment and flows within real reactors.
Objectives
- To refresh and understand reaction kinetics and reaction thermodynamics
- To understand the concepts of governing steps and multi step reaction schemes
- To refresh types and classifications of chemical reactions and reactors
- To understand the fluid flows within vessels
- To understand multi phase, multi component flows
- To understand the differences of ideal vs real industrial reactors
- To see how simulation helps to design, optimize and troubleshoot industrial reactors
- To understand catalytic reactors
- To understand competitive phenomena via dimensionless numbers
