The feed (equimolar A and B) to a reactor is heated from (100^{circ} mathrm{F}) to (500^{circ} mathrm{F})

Question:

The feed (equimolar A and B) to a reactor is heated from \(100^{\circ} \mathrm{F}\) to \(500^{\circ} \mathrm{F}\) in a \(1-2\) parallel-counterflow heat exchanger with a mean overall heat-transfer coefficient of \(75 \mathrm{Btu} / \mathrm{hr}-\mathrm{ft}^{2{ }^{\circ} \mathrm{F}}\). It is converted to \(\mathrm{C}\) by the exothermic reaction \(\mathrm{A}+\mathrm{B} \rightarrow \mathrm{C}\) in an adiabatic plug-flow tubular reactor (Figure 7.35). For a process simulator, prepare a simulation flowsheet and show the calculation sequence to determine:

(a) Flow rates and unknown temperatures for each stream.

(b) Heat duty and area of the countercurrent shell-and-tube heat exchanger.
