ISOTHERMAL BATCH REACTOR APPARATUS

ISOTHERMAL BATCH REACTOR APPARATUS Description: A batch reactor is a closed system with no input and output streams. A batch reactor can operate under conditions like Isothermal (Temperature of Reaction Mass remains constant), perfectly mixed (composition of reaction mixture is uniform throughout), and constant volume (volume of the reaction mixture within the reactor remains constant, there is no appreciable change in the density of reaction mass). 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. 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.

In an ideal Plug Flow Reactor (PFTR) there is no mixing in the direction of flow and complete mixing perpendicular to direction of flow. Concentration of reactants varies along the length of reactor but not in radial direction. In case of a coil turbulence is introduced due to frequent change in direction of flow and presence of secondary flow, so a higher value of reaction rate constant is expected in coil tube type plug flow reactor. In an ideal CSTR the contents in reactor are well mixed and have uniform composition throughout. Thus the exit stream has the same composition as the fluid within the reactor. The set up consists of two feed tanks through which two reactants are fed to the reactors fitted in series. Rotameters are provided to measure the individual flow of Chemicals. The flow rate can be adjusted by operating the needle valves provided on respective rotameter.
