Characterization of a 5 Litre Continuous Stirred Tank Reactor

Characterization of a 5 Litre Continuous Stirred Tank Reactor

the ideal RTD for a continuous stirred tank reactor [7]. Continuous stirred tanks are used ubiquitously in the chemical process industry for mixing, reactions, and crystallizations. The mixing in a continuous stirred tank is often not ideal. The residence time distribution (RTD) is one of the ways to characterize the non-ideal mixing in the tank.

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.
