Goal Seek calculations intercept

The Table J.2 Goal Seek calculation also shows that the intercept gas contains ... 

Fig. 19.5. Equilibrium curve, heatup path and heatup path-equilibrium curve intercept for after-intermediate-FESOj-making catalyst bed. Attainment of equilibrium in the catalyst bed gives 98.9% oxidation of the bed s input S02. The lines apply only to the graph s specified inputs and bed pressure. This graph is a blowup of Fig. 19.6. Its intercept is confirmed by a Goal Seek calculation in Appendix T. The S02 and 02 inputs are equivalent to 0.234 volume% S02 and 7.15 volume% 02.

The actual intercept value is determined by the Goal Seek calculation in Section J.4. 

This causes any change in feed gas composition (Cells E2, G2, 12, K2) to be reflected in the matrix. It allows new intercepts to be calculated at will (using only Goal Seek).
