Product Description

COMBINEDFLOW REACTOR APPARATUS

COMBINED FLOWREACTOR APPARATUS

This set-up is used to study a non-catalytic homogeneous secondorder liquid phase reaction under ambient condition in a combined reactor.

It consists of two reactors connected in series; one is plug flowreactor and another is CSTR. In an ideal Plug Flow Reactor (PFTR) there is nomixing in the direction of flow and complete mixing perpendicular to directionof flow. Concentration of reactants varies along the length of reactor but notin radial direction. In case of a coil turbulence is introduced due to frequentchange in direction of flow and presence of secondary flow, so a higher valueof reaction rate constant is expected in coil tube type plug flow reactor. Inan ideal CSTR the contents in reactor are well mixed and have uniformcomposition throughout.

Thus the exit stream has the same composition as the fluid withinthe reactor. The set up consists of two feed tanks through which two reactantsare fed to the reactors fitted in series. Rotameters are provided to measurethe individual flow of Chemicals. The flow rate can be adjusted by operatingthe needle valves provided on respective rotameter. The compressed air is usedfor 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 fedto CSTR fitted with stirrer for proper mixing. Samples are collected foranalysis. Pressure Regulator, Pressure Gauge and Safety Valve are fitted in thecompressed air line.
