Energy balance CFSTR

The following derives an energy balance for a CFSTR based on the following assumptions (Figure 6-2) ... 

In a CFSTR, it is necessary to perform a material and an energy balance on an element of the system to understand its behavior. 

Consider a jacketed CFSTR with an external jacket as shown in Figure 6-27 in which the coolant fluid temperature Tc is not maintained constant. This situation requires solving an energy balance equation on the coolant along with the mass and energy balance... 

For the minimum volume in a CFSTR under adiabatic condition, Equation 6-192 requires only that the operating temperature within the reactor be Topt. In this case, there is nothing about the mode of operation, such as the feed temperature T0 or heat transfer, either within the reactor or upstream of it. However, if the CFSTR is operated adiabatically for specified conversion (XA) and molar flowrate (FAO = uCAO) without internal heat transfer, T0 must be adjusted to a value obtained from the energy balance as determined by...
