PPT Slide
- Easy for single phase liquids and slow reactions
- Harder if very exothermic, very fast kinetics or multiple reactions (heat transfer and mixing)
- Harder still for multi-phase systems (mass transfer effects)
- Very hard for multiphase systems with high heat transfer loads, fast kinetics and multiple reactions (heat transfer, mass transfer, mixing)
If yields and selectivities are to be the same on the small scale in the laboratory and on the full scale plant then the molecules must experience the same temperature – concentration – time – space history
