WebFigure 1: Schematic diagram of a CSTR. A model of the CSTR is required for more advanced control approaches. The inlet stream of reagent A is fed at a constant rate F. After stirring, the end product streams out of the vessel at the same rate as reagent A is fed into the tank (the volume V in the reactor tank is thus kept constant). WebThis small slice of fluid behaves like a small CSTR reactor : it is very small and thus assumed perfectly agitated, and it is in steady state. The mass balance for the volume dV can then be done, using the general mass balance equation : F A,i = F A,o + r' A.dV + dn A /dt. With : FA,i : the molar flow at the inlet of the slice dV ... side effects of ace and arbs
