Lecture 24: Continuously stirred tank reactors - Chemistry .

Simultaneously, an exit stream is extracted from the reactor at the same flow rate as the inlet stream to maintain a constant volume inside the reactor. CSTRs allow for the continuous production of the desired chemical without the need to repeatedly empty and fill the tank. Figure 24.1 displays diagrams for a batch reactor and CSTR.

History. The concept of residence time originated in models of chemical reactors. The first such model was an axial dispersion model by Irving Langmuir in 1908. This received little attention for 45 years; other models were developed such as the plug flow reactor model and the continuous stirred-tank reactor, and the concept of a washout function (representing the response to a sudden change .

Continuous Stirred Tank Reactor

Thus the exit stream has the same composition as the fluid within the reactor. This type of reactor is known as mixed flow reactor. This set-up is used to study a non-catalytic homogeneous second order liquid phase reaction under ambient condition. The set up consists of two feed tanks through which two reactants are fed to the reactor.

Chemical reactor - Wikipedia

Continuous stirred-tank reactors (CSTRs) are frequently used plants in the chemical and food industries. Control of CSTRs is a challenging problem due to the non-linear behaviour, multiple steady-states, heat effect of the chemical reactions, time delay, and effect of various time-varying uncertainties, see ( Luyben, 2007, chap. 1 ).
