The flow rate can be adjusted by operating the needle valve provided on Rotameter.
Axial diffusion and dispersion of fluid in packed beds are important for
design and operation of separation equipment and Chemicals reactors.
The tracer technique, the most widely used method for the study of axial dispersion.
The setup consists of a glass column packed with Rasching Rings and one feed tank.
Water is fed to the reactor through a liquid distributor, fitted at the bottom of the column.
Rotameter is provided to measure the flow of water.
In stimulus-response experimentation, we perturb the system using pulse
input of tracer and then see how the system reacts or responds to this
The analysis of the response gives the desired information about the system.
Samples can be taken periodically from the top outlet of the reactor.
For understanding the R.T.D. characteristics, a special arrangement to
inject a tracer into the lower end of the reactor, using a syringe, is
Pressure Regulator & Pressure Gauge are fitted in the compressed air line.
To plot RTD curve for Packed Bed Reactor.
To determine the Dispersion No.
