2.3.1 CSTR (Also Known as a Backmix Reactor or a Vat)

Recall that the CSTR is modeled as being well mixed such that there are no spatial variations in the reactor. For the general reaction,

the CSTR mole balance Equation (1-7) can be arranged to

We now substitute for FA in terms of FA0 and X

and then substitute Equation (2-12) into (2-11)

Perfect mixing

Simplifying, we see that the CSTR volume necessary to achieve a specified conversion ...
