| Abstract: | A detailed derivation of the model for calculation ofcomplex gas-phase reaction equilibria has been given on the basis of the atom free energy contribution concept. This model is particularly suitable for the case where the details of s tochichemical equations are unavailable, such as the Claus complex reaction system. Satisfactory results' are obtained when the method is applied to the Claus main combustion furnace and reheat burner. The paper provides theoretical proof and method for exact process design and optimization. The program developed for computer aided design is universal and rapid in calculation. |
