5.5.4 Analytical Solution for Reaction with Pressure Drop

How will pressure drop, ΔP, affect our calculations?

Let’s reason out how pressure drop affects our CRE algorithm. Figure 5-8 shows qualitatively the effects of pressure drop on reactor design. Starting with Figure 5-8(a) we see how the Ergun equation predicts the pressure decrease down the packed-bed reactor. The subsequent figures, (b) through (e), show this effect of pressure drop on concentration, reaction rate, conversion, and volumetric flow rate, respectively. Each of these figures compares the respective profiles when there is a pressure drop with those profiles for no pressure drop. We see that when there is pressure drop in the reactor, the reactant concentrations, and thus ...
