What is the plan? In the following pages we manipulate Equation (11-9) in order to apply it to each of the reactor types we have been discussing: batch, PFR, PBR, and CSTR. The end result of the application of the energy balance to each type of reactor is shown in Table 11-1. These equations can be used in Step 5 of the algorithm discussed in Example E11-1. The equations in Table 11-1 relate temperature to conversion and to molar flow rates and to the system parameters, such as the overall heat-transfer coefficient and area, Ua, with the corresponding ambient temperature, Ta, and the heat of reaction, ΔHRx.
