Een Lussysteem voor Hybride Amine-Ondersteunde CO2-Afvang en Minerale Carbonatatie

Anthropogenic CO2 emissions have significantly increased, with an average annual release of 18.7 billion tons over the past decade, raising atmospheric CO2 levels to 416 ppm. To mitigate the resulting greenhouse effect, technologies such as Carbon Capture, Utilization & Storage (CCUS) are being explored. Amine-based CO2 capture is efficient but energy-intensive. This thesis investigates a novel hybrid technology, CO2 Capture-Mineral Carbonation (CCMC), which combines amine absorption with mineral carbonation using alkaline waste streams. The study focuses on optimizing the CCMC process, including selecting effective amines and understanding the mechanisms involved. It was found that tertiary amine DEAE showed high carbonation efficiency and stability, while amine structure, basicity, and other factors influenced the reaction rates and product quality. The thesis also explores amine recovery using bipolar membrane electrodialysis (BMED), achieving high recovery rates and efficiency. A techno-economic analysis demonstrated the feasibility and potential profitability of a closed-loop CCMC system, despite high operational costs, highlighting its industrial applicability.
