Presentation Title PreMa-project Development of New Technologies to Reduce CO2 Emissions in Mn-alloy Production
Author(s) Eli Ringdalen
On-Site Speaker (Planned) Eli Ringdalen
Abstract Scope PreMa is an EU Horizon 2020 project developing technologies to reduce CO2 emissions and consumption of electrical energy in Mn-alloy production. The main concept is to pretreat Mn-ores in a separate unit prior to final alloy production in submerged arc furnace. Various pretreatment technologies using different energy sources like CO-rich industrial off-gas, bio-carbon and solar thermal are investigated and will be developed and demonstrated. Investigations of selected industrial Mn-ores are done on different scales. Kinetic parameters are determined and effect of various pretreatment conditions on industrial materials are investigated in laboratory scale. Different pretreatment technologies and subsequent alloy production from produced materials are tested in pilot scale. Environmental effects are assessed, and process flow sheets compared by modelling. The paper gives an overview over the process concept, how the different parts are linked, and main results from the investigations.
