Model 2 The Ideal Continuous Stirred Tank Reactor CSTR with V Constant

2 Model 2 The Ideal Continuous Stirred Tank Reactor (CSTR) with V = Constant 

If one uses the quantity t [/i] = mean residence time or the quantity D = dilution rate of the fluid phase (cf. Equ. 3.47) 

In the steady state dcjdt = 0), one obtains the following mass equation for the CSTR 

for example, one is dealing with a microbial growth process in a CSTR, the Xj = 0, and one may apply Equ. 2.5a for the rate of growth and thereby obtain the well-known relations for the equilibrium state. This is the basis for the CSTR, the so-called chemostat or realstat mode of operation of a continuous fermentation process (see Sect. 6.1).
