Isothermal Plug Flow Reactor Apparatus

Model Number: KMS-1 Key Specifications/Special Features: Isothermal plug flow reactor apparatusTechnical description: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. This set-up is used to study a non-catalytic homogeneous reaction under isothermal condition. The set up consists of two feed tanks through which two reactants are fed to the reactor. 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. It is a helical coil tube type reactor kept in a constant temperature water bath to conduct the experiment at various temperatures. Reactants enter at lower end coming out of the top of coil from where samples are collected for analysis. Pressure regulator, pressure gauge and safety valve are fitted in the compressed air line.Learning objectives/experiments:Specifications reaction study in isothermal plug flow reactor.To determine reaction rate constant and effect of temperature on it.Required for operation:
