Heatup paths plots

Prepare a heatup path for 12 volume% S02, 13.2 volume% 02, 74.8 volume% N2, 675 K feed gas - as described in Appendix I. Plot the path with Excel s Chart Wizard function. 

Table 12.1 % S02 oxidized-temperature points near heatup path-equilibrium curve intercept. They have been calculated as described in Appendices I and D. They are plotted in Fig. 12.1. and E are defined by Eqns. (10.1) and (10.2).

Fig. 12.1. Plot of Table 12.1 heatup path points and equilibrium curve, expanded from Fig. 11.7. Below the equilibrium curve, S02 is being oxidized, gas temperature is increasing and equilibrium is being approached up the heatup path. Maximum (equilibrium) oxidation is attained where the heatup path meets the equilibrium curve.

The 2nd catalyst bed heatup path is prepared by re-doing Section 14.9 s calculation for many different temperatures in the bed. Only cells HI5 to K15 are changed (most easily with enthalpy equations in cells, Appendix K). The results are tabulated in Table 14.3 and plotted in Fig. 14.3.
