In reaction engineering, the average residence time 7 is the amount of time an element of fluid spends in a reactor and is related to the amount of substance present in the system. The easiest method to determine 7 is via a pulse stimulus, where a small amount of a tracer is put into a reactor operating under steady state and the effluent concentration is measured over time.

Transcribed Image Text:1. In reaction engineering, the average residence time 7 is the amount of time an element of fluid
spends in a reactor and is related to the amount of substance present in the system. The easiest
method to determine 7 is via a pulse stimulus, where a small amount of a tracer is put into a
reactor operating under steady state and the effluent concentration is measured over time. The
average residence time is calculated as:
