COMBINED FLOW REACTOR APPARATUS

Product Description

This set-up is used to study a non-catalytichomogeneous second order liquid phase reaction under ambient condition in acombined 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 mixingperpendicular to direction of flow. Concentration of reactants varies along thelength of reactor but not in radial direction. In case of a coil turbulence isintroduced due to frequent change in direction of flow and presence ofsecondary flow, so a higher value of reaction rate constant is expected in coiltube type plug flow reactor. In an ideal CSTR the contents in reactor are wellmixed and have uniform composition throughout.

Thus the exit stream has the same composition asthe fluid within the reactor. The set up consists of two feed tanks throughwhich two reactants are fed to the reactors fitted in series. Rotameters areprovided to measure the individual flow of Chemicals. The flow rate can beadjusted by operating the needle valves provided on respective rotameter. Thecompressed air is used for circulation of feed. 1st is a helical coil tube typereactor made up of SS pipe. Reactants enter at lower end coming out of the topof coil from where it is fed to CSTR fitted with stirrer for proper mixing.Samples are collected for analysis. Pressure Regulator, Pressure Gauge andSafety Valve are fitted in the compressed air line.
