Some considerations in detailed design

Exercise 7.3,4. Discuss the possible form of the heat generation curve for the first order reactions A — B — C when the second reaction is endothermic. 

Exercise 7,3.5. Using the notation of Sec. 4.4 and Exercise 4.4.3, show that if + Cgo) = jy is the dimensionless holding time, then the steady 

Exercise 7.3.6. Show that if the greatest production (i.e., greatest value of is required from a given reactor for a single exothermic reaction, then the heat removal line should pass through the highest point of the heat generation curve (see Fig. 7.10). 

Exercise 7.3.8. A second order reaction A B — 2C is taking place in the liquid phase in a continuous flow stirred flask of one 1 capacity. The feed concentrations of both A and B are (20/3) gm-mole/1 and the flow rate lOOcm niin their heat capacity is 650cal/UC the rate constant is 33 x 10 exp — 20,000/R7 1/mole min the heat of reaction 

To illustrate how the steady state equations lead back to the considerations that have to be faced in detailed design and cost analysis, let us sketch the
