PREMA – Energy efficient, primary production of manganese ferroalloys through the application of novel energy systems in the drying and pre-heating of furnace feed materials

PREMA is a H2020 project aimed at demonstrating an innovative suite of technologies, involving utilization of industrial off-gases and solar thermal energy to reduce energy consumption and CO2 emissions from manganese production as a means to obtain sustainable production of Mn-alloys and steel.

The main concept of PREMA is to increase energy flexibility and allow the use of sustainable energy sources and reduce the overall energy consumption and CO2 emission in Mn-alloy production. This will be done by dividing the Mn-alloy production, today done in submerged arc furnaces (SAF), into two separate units as illustrated below. A pretreatment unit will be added before the existing furnace. Within the project various pretreatment technologies using different energy sources like: CO-rich industrial off-gas, bio-carbon and solar thermal energy will be developed and demonstrated.

Integration of the novel PREMA pretreatment technologies with the process currently used by smelters will lead to a better flexibility in terms of raw materials leading to a 20% reduction in the consumption of fossil carbon, more energy efficient production processes giving a potential for a 20% reduction in overall energy consumption and a global reduction of operation costs by at least 10%.
