Description du projet
Production durable d’alliages de manganèse
Le manganèse est le deuxième métal de transition le plus abondant après le fer. La majeure partie du manganèse créé est exploitée sous forme d’alliages de ferromanganèse et de silicomanganèse pour la production d’acier et de fer. Cependant, la production d’alliages de manganèse consomme énormément d’énergie et est responsable de l’émission de grandes quantités de CO2. Le projet PreMa, financé par l’UE, fera la démonstration d’une série de technologies de prétraitement du minerai de manganèse permettant d’utiliser plus efficacement les flux d’énergie et de matières et de réduire les émissions de CO2. PreMa étudiera des technologies innovantes de récupération de l’énergie, notamment des effluents gazeux riches en CO2 et de la chaleur résiduelle. Les chercheurs se sont fixé des objectifs ambitieux: 5 % de réduction des coûts d’exploitation, 20 % d’augmentation de l’efficacité énergétique et 20 % de réduction des émissions totales de CO2.
Objectif
Global Manganese-alloys (Mn) are highly linked to the steel sector for key engineering applications in Europe. In 2017, Mn-alloy production was approx. 4 Mio tons, required 12,200 GWh electrical energy and emitted around 14.2 Mio tons of CO2. Therefore, an energy intensive and inherent cross-sectorial value chain that is, nowadays, led by the Asian market demand. PREMA is an ambitious initiative that aims at demonstrating an innovative suite of technologies (involving heat recovery and solar technologic approaches) that allow to pre-treat Mn ores, utilising more efficiently energy and material streams and decreasing direct and indirect CO2 emissions (along with SO2 and NOx). LCA and LCCA methodologies will be implemented from early stages to ensure the technical, economic and environmental viability of the solution across the whole Mn-alloys’ value chain. The vision of PREMA is thus to make the Mn-alloys sector in Europe more flexible, sustainable and attractive. In order to cover the whole value chain, there is a strong presence of South African (SA) partners in the consortium, SA being the top 1 in high quality Mn ores’ extraction and exports worldwide. A win-win situation in order to strengthen the Mn-alloys and steel value chains in Europe. PREMA consortium puts together a total of 11 production facilities spread over Europe and SA among 4 Mn producers, representing an aggregated process capacity of 380 MW (Transalloys in SA, Eramet in France and Norway, Ferroglobe in Norway and Spain and OFZ in Slovakia). The innovative character of the project is brought by major players in R&D across Europe and SA, with the Norwegian organisation SINTEF as coordinator. Last but not least, clustering with other EU initiatives, including other SPIRE projects, will be paid special attention in order to create awareness of the project developments from early stages of the demonstration.
