| Abstract [eng] |
Cement is one of the most abundant building materials, which requires significant resources and the production of which has a significant impact on the environment. As much as 5% of total carbon emissions come from cement production. At present, the concentration of carbon dioxide in the atmosphere is 0.041%, the highest in 650,000 years and growing rapidly, so opportunities need to be explored to reduce and use CO2. One option is to capture carbon dioxide using a "post-combustion" system. However, it needs to be assessed whether the use of collection systems will not cause more damage to the environment. Therefore, this master thesis carried out a life cycle assessment for cement production and analyzed three alternatives: cement production without carbon dioxide capture, carbon capture using post-combustion system with a monoethanolamine solvent, and collection using the same system but with a solvent changed to diethanolamine. |
