Abstract

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.
