MODEL: BP 151

HE Benchtop CSTR in Series (Model: BP 151) has been designed as an economical way 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.
