Heatup path preparation

The heatup path for the Section 11.5 feed gas is prepared by re-doing the above calculation for many different levels and temperatures in the catalyst bed, Fig. 11.4. Only cells G8 to J8 in Table 11.2 are changed. 

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. 

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. 

Preparation of these heatup paths requires S03, S02, 02, N2 and C02 enthalpy values and equations over this temperature range. This appendix ... 

Table J.l. Worksheet for calculating 1st catalyst bed heatup path-equilibrium curve intercept. Preparation instructions are given in Section J.3. Operating instructions are given in Section J.4. Notice that equilibrium curve % S02 oxidized (cell FI 1) heatup path % S02 oxidized (cell 139). So 894.2 K in cells A14 and J30 is not the intercept temperature. The intercept value is calculated in Table J.2.
