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.

A continuous stirred tank glass reactor design is simply a batch reactor which comes with an impeller. Apart from the impeller, it can as well have other mixing devices aimed at increasing the efficiency of the mixing liquids. It is also referred to as the agitated reactor.Some processes require continuous mixing so that the desired effects can be realized.

Experimental data from loop reactors show that the desired oxygen transfer is possible by all means: 350 mol/m3 hr corresponding with 10kg/m3 hr; this in contrast with traditi onal stirred tank reactors. Easthouse is currently developi ng a reactor, com bined wi th a stirred tank and an external loop.

Thus far in our study of chemical kinetics, we have considered reactions in isothermal batch reactors, in which reactions taking place in closed containers maintained at a constant temperature. While such reactions are commonplace in chemistry labs, most industrial processes instead use continuously stirred tank reactors (CSTRs).

Stirred Tank Reactor. A stirred tank reactor (STR) is probably the most common type of reactor found in industry. Mixing is achieved via stirring using an impeller, and aeration is done via a sparger (a pipe that pumps in air). Baffles are also used in STRs to reduce vortexing (mini whirlpools) of the fluid.

While such reactions are commonplace in chemistry labs, most industrial processes instead use continuously stirred tank reactors (CSTRs). In these reactors, reactants are continuously flowed into the reactor, where they undergo a chemical reaction.

I. Stirred Tank Reactor Ideal CSTR has an exponential RTD and is perfectly mixed on a molecular level i.e, is in the state of maximum mixedness. Can the exponential RTD and perfect molecular mixing be approached in practice? It depends on the design and operation of the stirred tank and on the characteristic reaction time.
