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.

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.

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.
