In an industrial jacketed reactor, we have two temperature probes:
- one on a baffle the extends down about to the 50% fill line
- one built into reactor, very close to the bottom valve.
When is it more reliable and practical to use one location over the other when monitoring and controlling the temperature in a chemical process? Please ignore obvious situations, such as the liquid level is too low for the baffle so the bottom must be used.
I've heard some reasons for each location. For example, baffle temperature is best when reacting at a constant temperature, or when a slurry presents possible solids buildup on the bottom probe.
Are there any solid industry best practices relating to this?
