The scope of this presentation is to introduce ChemApp, a thermodynamic software interface consisting of a library of Fortran subroutines based on the phase equilibrium calculation module of ChemSage. Potential applications for the use of the ChemApp routines in programs for handling repetitive complex equilibrium calculations are almost limitless and can cover an extremely diverse range of applications. ChemApp can for instance be linked into any third-party process simulation package, CFD programs (Phoenics, Fluent) and general simulation programs (Aspen Plus, Apros) included. In this paper, the most important features and subroutines of the ChemApp interface are discussed and demonstrated through examples.
