2. Experimental determination of residence time distribution
The method involves using a tracer to mark molecules at the reactor inlet, and using a suitable detector to count these molecules in the outlet stream as a function of time.
To get as close to reality as possible, we need to use a tracer with the same hydrodynamic properties as the fluid, and ensure that the detector's analysis does not locally disturb the fluid's hydrodynamics.
2.1 Various disturbances
Tracer injection can be carried out using a variety of disturbances dictated by the environment in which the reactor under study is located.
Pulse injection is generally used on small installations, and involves injecting the desired quantity of tracer over a very short period of time. These injections can be...
