SO2 Oxidation Heatup Paths

Fig. 12.6. Effect of CO2 on intercept temperature and % SO2 oxidized. Heatup path slope increases slightly with increasing CO2 in gas - because CO2 heat capacity is greater than N2 heat capacity, Appendix G. This decreases intercept temperature and increases % SO2 oxidized. CO2 calculations are described in Chapter 17.

Table M.l. Worksheei for determining 2" catalyst bed heatup path-equilibrium curve intercept. The non-zero equilibrium curve % SO2 oxidized - heatup path % SO2 oxidized value in cell G47 indicates that cell FI I s suggested 94% SO2 oxidized is not the intercept value. The actual intercept value is calculated in Table M.2.
