Energy utilisation at Mo Industripark

Sammendrag

Process data has been collected to describe the energy flows between industrial clients located at Mo Industripark (MIP). The annual energy flow (in GWh) has been visualised in the form of Sankey diagrams while the quality of the available energy is presented in the form of a grand composite curve which describes the amounts of latent energy available at different temperature levels. High temperature flue gas from ferrosilicon (FeSi) production at Elkem Rana represent the largest heat source available for utilisation. A theoretical assessment of potential applications for this energy is presented and includes: 1) electricity production (via a steam Rankine cycle); 2) biocarbon production, where surplus heat is utilised for drying of wood chips produced at MIP; 3) carbon capture (via amine based post combustion technology), where surplus heat is utilised for amine solvent regeneration. The theoretical studies indicate that the MIP ambition from 2016 of increasing the energy recovery from 400 GWh to 640 GWh is realistic and may contribute both to increasing the energy recovery and facilitate overall reductions in the carbon footprint of the activities at MIP. The three scenarios which have been explored theoretically are for simplicity closely linked to the Elkem production process. However, there are obvious synergies with the ferromanganese (FeMn) and silicomanganese (SiMn) production at Ferroglobe, both in terms of biocarbon production and carbon capture facilities. The existing CO network at MIP distributing CO rich flue gas from Ferroglobe is a valuable asset. Today CO gas is used for energy purposes by Celsa and SMA, but parts of the gas may also be a valuable resource for upgrading of pyrolysis oil from a future biocarbon production line. Investment in a common utility network for surplus heat may lower the threshold for establishing other energy clients at MIP. These are some of the possibilities which may be investigated in more detail in future work.
