Abstract Scope |
Glencore’s Sudbury Integrated Nickel Operations (Sudbury INO) Smelter produces Ni/Cu/Co Bessemer matte, which must meet strict Fe target limits. To provide a real-time Fe estimation, XPS developed a thermodynamic process simulator using a custom thermodynamic database. A proof-of-concept model implemented in MS-Excel and OSIsoft PI-Datalink reads measured values of matte mass, composition, totalized air, oxygen, flux, reverts and custom feed transferred to the finishing converter. The model identifies all the inputs to the vessel by correlating crane events, mass inputs and assays then predicts required amounts of oxygen and flux for each blow to achieve the target Fe, displaying the estimated Fe composition, slag quality and SO2 produced every minute. After initial successful plant-trial, the model, thermodynamic-library and database were ported to Emerson’s KNet analytics software for full integration into the plant control System. This article describes in detail the thermodynamic and convert model, plant trial results and KNet implementation. |
