Retention time distribution
Thread Content
I have a question: for a reactor, if it’s not possible to conduct tracer experiments, what other methods can be used to determine its residence time distribution and the flow patterns within the reactor? I would appreciate it if some experts in reaction engineering could help answer this. Thank you!~
Could it be simulated using Computational Fluid Dynamics (CFD)?
I’m not quite sure what type of reactor you have; it’s already possible to simulate three-phase mixing
Depending on the specific reactor design and reaction mode, deviation from the ideal state is inevitable. The main task of chemical engineering is to determine how to describe the factors that cause these deviations, to predict such issues, or to optimize situations where deviations have already occurred.
The residence time depends on the amount of material fed into the reaction and the amount of reactant produced, that is: amount of reactant produced / amount of material fed into the reaction = residence time； The flow direction of the materials inside the reactor is determined by the mechanism of reaction formation, which in turn determines the appropriate mixing equipment. Generally, in addition to controlling the intensity of mixing, the mixing equipment in a reactor must also have impeller shapes designed based on the mechanism of reaction formation.
