CAT NO: DIDACTICNSSE0033
Semi Batch Reactor.
Semi Batch Reactor A
isothermal semi-batch reactor is a semi-closed system with one input stream. It
is operated under conditions like Isothermal (Temperature of Reaction Mass
remains constant) and perfectly mixed (composition of reaction
mixture is uniform throughout). This set-up is used to study a non-catalytic
homogeneous reaction under isothermal condition. The set up consists of a
Reactor fitted in a constant temperature water bath. Before starting the
reaction the reactor is charged with measured quantity of one reactant. From a
feed tank another reactant is fed to the reactor. Using a sampling pipette
samples can be taken out for analysis after fixed interval. Rotameter is
provided to measure the flow of Chemicals. The compressed air is used for
circulation of feed. One stirrer is fitted for mixing the reactants in reactor
and other is fitted in water bath to keep the uniform temperature throughout in
the bath. The temperature of bath can be maintained from ambient to 70C with
the help of Digital Temperature indicator Cum Controller. Pressure Regulator,
Pressure Gauge and Safety Valve are fitted in the compressed air line.
