Continuously Stirred Tank Reactor Apparatus

Continuously Stirred Tank Reactor Apparatus

In an ideal CSTR (i.e. an ideal steady-state flow reactor) the contents in the reactor are well mixed and have uniform composition throughout. Thus the exit stream has the same composition as the fluid within the reactor. This type of reactor is known as a mixed flow reactor.


Description

In an ideal CSTR (i.e. an ideal steady-state flow reactor) the contents in the reactor are well mixed and have uniform composition throughout. Thus the exit stream has the same composition as the fluid within the reactor. This type of reactor is known as a mixed flow reactor. This setup is used to study a non-catalytic homogeneous second-order liquid phase 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. The CSTR is fitted with a stirrer for proper mixing. From the top outlet of it, samples are collected for analysis. Pressure Regulator, Pressure Gauge, and Safety Valve are fitted in the compressed airline.
