Abstract
CHEMSAGE, which was recently developed at Technische Hochschule Aachen in Germany, is a calculation software with a users-friendly interface for chemical equilibria. This software, based on the SOLGASMIX Gibbs energy minimizer, was designed to perform the calculation of thermodynamic functions, heterogeneous phase equilibria, and steady-state conditions for the simulation of simple multistage reactors. In this paper, the structure and characteristics of CHEMSAGE are introduced with some examples on the application of it for some metallurgical problems.
