Effect of Feed Gas SO2 Strength on Intercept

The industrial impact of these effects is discussed in Section 12.10.

Fig. 12.3 shows the effect of feed gas SO2 strength on intercept temperature and % SO2 oxidized. Increased SO2 strength is seen to ... 

Fig. 18.7 shows the effect of feed gas O2 strength on intercept SO2 oxidation efficiency. 

Fig. 12.5. Effect of feed gas O2 strength on constant SO2 strength heatup paths, equilibrium curves and intercepts. Intercept temperature and % SO oxidized increase slightly with increasing 02-in-feed-gas. Heatup path is barely affected by O2 strength - 3 paths are superimposed on this graph. The effect is small because ...

Fig. 18.6. Effect of 1 catalyst bed feed gas SO2 strength on intercept SO2 oxidation efficiency. The effect is significant after beds 1 and 2 but not after bed 3. The lower SO2 oxidation efficiency with higher SO2 strength is explained in Section 11.13.1 and Fig. 12.3.

Fig. 18.7. Effect of volume% 02 in feed gas on intercept S02 oxidation efficiency. % SO2 oxidized increases with increasing 02 strength - but the effect is small, especially after 3 catalyst beds.
