  • Continuous Stirred Tank Reactors | Flow Technology

    A Continuous Stirred Tank Reactor (CSTR) is a reaction vessel in which reagents, reactants, and often solvents flow into the reactor while the product (s) of the reaction concurrently exit (s) the vessel. In this manner, the tank reactor is considered to be a valuable tool for continuous chemical processing.

     · Continuous stirred tank reactors in series have been studied experimentally in detail for their dynamic behavior. By introducing the step and impulse input changes in concentrations and flow rates of reagents, the system is confirmed to be first order. The step and impulse response curves are found to be the sigmoid and exponential respectively.
