Chemical reactor - Wikipedia

When a reactor is brought into operation, either for the first time or after a shutdown, it is in a transient state, and key process variables change with time. There are three idealised models used to estimate the most important process variables of different chemical reactors: Batch reactor model, Continuous stirred-tank reactor model (CSTR), and

Fundamentals of Chemical Reactor Theory1

A Continuous-Stirred Tank Reactor (CSTR) is a well-mixed vessel that operates at steady-state (Qin=Qout=Q). The main assumption in this case is that the concentration of the incoming fluid will become instantaneously equal to the outgoing upon entering the vessel. Fig. 2 explains visually this concept. Fig. 2. Continuous-Stirred Tank Reactor
