Workshop 10.3b
The results are virtually identical to those of Workshop 10.3a. One
may observe from Figure 10.27, a plot of the results from a sensitivity study, that
450
◦
F is the optimal operating temperature.
Workshop 10.3c
The effect of pressure shown in Figure 10.28, a plot of the results
from a sensitivity study, is pronounced. Based on these results the optimal operating
conditions would be 450
◦
F and 14.7 psia. This analysis did not consider pressure
effects at other temperatures, and one might find another optimal solution. This point
is revisited in Chapter Thirteen.
Workshop 10.3d
Results of the case study show that low pressure favors hydrogen
formation and high pressure favors the formation of small quantities of dimethyl ether.
Methyl formate formation is negligible.
