The course aims to provide fundamental knowledge in multiphase reactors used in process industries

Train to carryout simple calculations on exchange coefficients of mass, energy and momentum, response times and coupling parameters in multiphase reactors

To make the students able in quantitative design of a multiphase reactor

After completion of the course the students will be able to:
1. Understand the basic types of multiphase reactors in process industries, their advantages and drawbacks
2. Quantify exchanges of momentum, heat and material in the separate phases and between phases in multiphase systems
3. Perform the preliminary design of Fixed Beds, Fluidized Beds (particulate, bubbling, turbulent and circulating) and three-phase reactors
4. Calculate response times and coupling parameters multiphase reactors and develop simple mathematical model in multiphase flows
5. Explain issues regarding formulating momentum-, energy- and material balance in multiphase systems
6. Make a quantitative design of a multiphase reactor for a given application
