SENSITIVITY ANALYSIS OF COMPLEX CHEMICAL-EQUILIBRIA IN HETEROGENEOUS SYSTEMS

Sensitivity analysis of an equilibrium multiple chemical reaction syst em with several pure condensed phases and one ideal gas phase is consi dered. It is shown that, in this case, response equilibria also play a n important role. The particularity of such systems is that the system 's response may be presented as a sum of contributions coming only fro m those response equilibria defined by gas phase species. The effect o f temperature, pressure and initial amounts of species is analyzed for gasification of coal (graphite).
