Preparing a Heatup Path

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. 

Inserted into Matrix Table 11.2, these values automatically give the result that 850 K gas is produced by 54.4% SO2 oxidation. 

An efficient method of calculating heatup path points is to put enthalpy equations directly into cells D8 - J8 of Table 11.2. This is detailed in Appendix I. 

The 850 K gas temperature at level L is, for example, represented by the enthalpy terms
