Sammanfattning

Mineral carbonation presents itself as the most promising method to sequester CO2 in Finland. A staged process for CO2 mineralisation, using magnesium silicates, is being intensively developed at Abo Akademi. Aspen Plus ® software was used to model the process and a pinch and exergy analysis were performed to acquire information on process layout for optimal heat recovery and integration. The simulations allow for concluding that the fixation of 1kg of CO2 requires 3.04MJ and 3.1kg of serpentinite mineral rock. Additionally, the process gives considerable amounts of goethite and Ca(OH)2 as by-products making the integration of mineral carbonation with the steelmaking industry a very attractive opportunity to reduce CO2 emissions and raw materials inputs.
