Reactions carried out in a CSTR eventually reach steady state when a certain amount of conversion of the starting reagents has taken place. The steady state conditions will vary depending on the reagents concentration, flow rate, reactor volume and reaction temperature. The design equation of a CSTR at steady state can be derived by making a material balance for reactant A around the reactor. The steady state mass balance for component A can be written as: Input=Output+DisappearanceFAA=FAA(1XA)+(rA)V or, FA0V=(rA)XA To achieve the same overall conversion, the total volume of three CSTRs in series is less than that required for one CSTR. Figure 1 shows a schematic diagram for the experimental setup. To achieve the same overall conversion, the total volume of three CSTRs in series is less than that required for one CSTR. Figure 1 shows a schematic diagram for the experimental setup. Fig. I: A Sketch of The ExperimentalSer-Up For three CSTRs in series, the conversion X at any point is the total number of moles of A that have reacted up to that point per mole of A fed to the 1 " reactor provided no side streams withdrawn and the feed stream enters only the 1" reactor in the series.
