The objective of this project is to develop a suite of documented Aspen models and accompanying training materials that focus on a minerals related project that incorporates both solids handling as well as chemical transformations to be used as teaching tools for second year Chemical Engineering module CHEE2002 – Process Systems Analysis.
Sodium cyanide is an inorganic chemical that is used extensively in mining industry for the extraction of gold ore. Therefore, its production process was chosen to be use to model this project’s objective. An important unit operation from the sodium cyanide production process such as the crystalliser was modelled and the training materials were developed.
This report documents the steps that were taken to develop the Aspen model. The model incorporated the use of an electrolyte method to handle the chemical transformations and solids handling aspects of the sodium cyanide production process.
Two training modules detailing the use of an electrolyte method and the validation of the electrolyte method were developed.
