SUMMARY:

The intensification of anthropological activity has led to an increase in greenhouse gas (GHG) emissions, which in turn affects differently the balance of the natural phenomenon known as the greenhouse effect. The gases that cause global warming, carbon dioxide (CO₂) produced by the post-combustion of fossil fuels aggravates the phenomenon, which is why it has the greatest effect (64%) in intensifying the phenomenon. Therefore, to reduce and neutralize high concentrations of CO₂ as well as corroborate energy transition measures, methods, and techniques have been addressed in the current scenario aiming to treat this component to enable its decarbonization. Carbon Capture, Storage, and Use Stations (CCUS) have been studied to reduce dirty gases and aim to integrate technologies with capture potential, including absorption, adsorption, amine looping, mineral carbonation, etc. In this sense, the present proposal aims to investigate the potential of amine-looping technology for the mineralization of carbon absorbed by monoethanolamine (MEA). Experimentally, CO₂ capture will be carried out in the presence of MEA solutions with different mass compositions under specific operating conditions (pressure, gas and liquid flow rates, temperature, and G/L ratio) in the presence of MEA solutions with different mass compositions. The mineralization reaction will be carried out under controlled operational conditions, with a study on the variable concentration of metal oxides (CaO and MgO). The carbonated products produced during the process and the regenerated MEA solution will be evaluated from morphological, thermogravimetric, and physicochemical perspectives. Based on the results obtained, a process model will be developed in the Aspen Plus® simulation environment (version 8.8) for subsequent technical-economic evaluation. Based on the reported experimental results and the applied model, the process will be optimized, and new conditions will be explored.
