ABSTRACT
Carbon capture technology is a significant step towards mitigating the effects of climate change. As the world continues to grapple with the challenges of global warming, carbon capture technology has emerged as one of the most promising solutions to reduce carbon emissions. Chemical absorption is one of the most widely used commercial carbon capture technologies, and amine is the most commonly utilized solvent. However, despite the progress made in this field, there is still room for improvement. To address this need for improvement, a quantitative study was conducted to understand the impact of CO2 physical properties and solvent selection on carbon capture process design parameters. The study collected data from research papers and journal articles published between 1937 and 2024, and the selected research papers were based on their relevance to the research objective and their contribution to the understanding of the design of carbon capture technology. The study identified key themes, concepts, and methodologies pertaining to CO2 capture processes and process design considerations. The quality and rigor of the selected research papers and the journals were critically evaluated to assess the reliability and validity of the data. The data were analyzed using various metrics such as CO2 concentration %, gas flow rate, distance from the bottom of the distillation column, packer surface area, packer void fraction, number of film segments, and CO2 out. The results of the study show that lower density requires a large column diameter and vice versa. Denser liquids tend to have a higher viscosity, which leads to higher pressure across the column. Moreover, the mass transfer of CO2 through the gas film is reduced when the viscosity of the gas phase increases. These findings provide valuable insights into the impact of CO2 physical properties and solvent selection on carbon capture process design parameters, which would aid other researchers in the development of new materials for improving CO2 capture. Overall, this study highlights the importance of continued research and development in the field of carbon capture technology. As climate change continues to pose a threat to our planet, it is essential to explore and implement innovative solutions to reduce carbon emissions. This study is a significant step towards achieving this goal, and it is hoped that the findings will inspire further research and development in this critical field.
