Equilibrium in ProMax
March 30, 2007
Like the Gibbs Minimization reactor, the Equilibrium reactor in ProMax also calculates chemical equilibrium. However for this reactor stoichiometric equation information must be entered by completing the data for a Reaction Set. The required equilibrium constant may be determined by one of two options. ProMax can calculate the equilibrium constant from the Gibbs free energy or it can be entered by the user as a function of temperature. A temperature approach to equilibrium can be specified based on pilot plant data or plant experience. Isomerization reactors for paraffin or xylene isomerization are often be modeled as equilibrium reactors.
