Mathematical Modelling and Numerical Simulation of a COREX® Reduction Shaft

Problem:
COREX® is an ecologically beneficial process for iron production, which has been developed by VOEST Alpine Industrieanlagenbau. In a 3D process simulation model of the COREX® reduction shaft, the gas and solid flow, the energy balances, the chemical reactions and the dust deposition are to be calculated. This development was a joint project of Siemens VAI Metals Technologies GmbH & Co, the Industrial Mathematics Institute and MathConsult.

Results:
Left: the pressure distribution in the solid material
Center: the temperature distribution in the gas flow
Right: the mass fraction of FeO in iron ore

Transferable expertise:
Mathematical modelling of complex technical processes, numerical simulation in process engineering.
