Plug Flow Tubular Reactor (Straight Tube Type) apparatus

In an ideal Plug Flow Reactor (PFTR) there is no mixing in the direction of flow and complete mixing perpendicular to the direction of flow. The concentration of reactants varies along the length of the reactor but not in the radial direction. This setup is used to study a non-catalytic homogeneous reaction under ambient conditions. The setup 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 the respective Rotameter. Compressed air is used for the circulation of feed. A straight tube-type reactor is kept horizontally and inclined upward at the outlet from where samples are collected for analysis. Pressure Regulator, Pressure Gauge, and Safety Valve are fitted in the compressed airline.
