CSTR IN SERIES

MODEL: BP 107

HE CSTR In Series (Model: BP 107) has been designed to introduce students of Chemical Engineering

on the dynamic behaviour of reactors in series. The unit is based on the simplest classic case of a well-

mixed, multi-staged process operation that basically consists of three reactors connected in series by

piping. The solution in each reactor is well stirred and the concentration can be measured. Sump tanks, feed pumps

and instrumentations are also provided with the unit.

Students shall be able to compare the measured

responses of the vessel concentrations to a deliberate

change at the inlet with a theoretical prediction. The

piping arrangement has been designed to include a

“dead time” coil in the system. Feed liquid to the first

vessel is drawn from either of the two sump tanks by a

pump, via a flowmeter and control valve. The tracer

material concentration in each sump tank is made to be

different. At a selected instant, a sudden change from

one feed to the other is made: either for a continuous

period (“step function”), or for a short interval (“impulse

function”), and the concentration changes with time in

each vessel is measured. The results are compared

with the predicted exponential responses for 1st

order

system in series.
