Combined Flow Reactor Apparatus - Application: Chemical Engineering Laboratory Equipments

This set-up is used to study a non-catalytic homogeneous second order liquid phase reaction under ambient condition in a combined reactor.
It consists of two reactors connected in series; one is plug flow reactor and another is CSTR. 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. The compressed air is used for circulation of feed. 1st is a helical coil tube type reactor made up of SS pipe. Reactants enter at lower end coming out of the top of coil from where it is fed to CSTR fitted with stirrer for proper mixing. Samples are collected for analysis. Pressure Regulator, Pressure Gauge and Safety Valve are fitted in the compressed air line.
