Increase the utility feed rate by \(50 \%\), and maintain the base-case process feed stream.

a. Determine the conversion obtained.

b. Determine the percent change in the acetone produced.

Problems 23. 21-23.26 investigate the performance of the acetone reactor system. The reaction kinetics are presented in Section 23. 5.3. The reactor and internal heat exchanger are fixed. For the base case, the active volume of the reactor is \(5.1 \mathrm{~m}^{3}\) at the operating conditions given in Figure 23. 10. Unless otherwise stated, the heat transfer coefficient and reactor pressure drop are to be assumed constant. The feed temperature, pressure, and component concentrations remain constant. For these calculations, assume the utility fluid to be n-heptadecane (at pressures more than \(30 \mathrm{bar}\) ). At the base case, the utility flow is \(58 \mathrm{kmol} / \mathrm{h}\).
