Thermodynamic Process Modelling

Experience has shown us that it is not sufficient to know that something occurs - we need
to know why. Therefore, it is important to understand the background of a process and be aware of the fundamental influences and interrelationships. METTOP FIS uses thermodynamic software (e.g., HSC Chemistry and FactSage™) to model metallurgical processes.

The customer-specific process information is used to create a thermodynamic process model, which subsequently serves as a tool for optimization:

• Design of new processes
• Plant and furnace layout
• Optimizing existing processes

The advantages of thermodynamically modelling pyrometallurgical processes are that decisions are not only made on the basis of experience and estimations but on a combination of founded figures and experience. Entire process streams can be examined in relation to multiple aspects including the chemical reactions, input amounts, and the heat balance.

The model should represent a comprehensive combination of empirical data and thermodynamic calculations that supports planning, ongoing operations, and optimization, and can also be used for training purposes.
