| Abstract Scope |
A numerical model of iron ore reduction process on pilot and industrial scale was built using finite element analysis on COMSOL Multiphysics. A 2D-axisymmetric geometry was used to build the pilot scale model at a steady-state, and it was validated using the experimental metallization data obtained from the GISH project pilot campaigns. The pilot scale model was scaled-up to an industrial scale reactor by increasing the diameter of reactor model geometry from 0.254 m to 7 m, and pellet feed rate from 206.6 ton/year to 3.34 million ton/year. The scale up of pilot scale model is needed to account for the changes in the energy consumption and mass fraction profiles of the solid species. The mass balance data obtained from the reactor model simulation was used to perform techno-economic analysis and determine the economic penalty when moving from a pure natural gas operation to a pure hydrogen operation. |
