Direct air capture system: a feasibility study for Izmir

This study aims to reduce 1% of the annual emissions in the city of Izmir. In line with this target, this study worked on the integration of a liquid solvent-based DACS system within Izmir. Primarily, the emissions within the city boundaries were calculated based on the calculation method of each sector. For the mentioned target, each component's energy requirement of the KOH solvent-based DACS system was calculated in detail. According to these calculations, the system's total energy requirement, economic, and area calculations were obtained. As a result, the total emission amount was calculated as 11,809,362 tCO(2). Total needed energy, area, and cost for DACS system resulted to be 1,169 kJ kg(-1), 12,527 m(2), and $136.6 million, respectively. In addition to numerical results, DACS is the most logical solution apart from increasing environmental awareness for creating a better, stronger, and environmentally friendly city for the near future.
