Description

Direct Air Capture (DAC) technologies are gaining increasing attention as a key component of future carbon-neutral energy and industrial systems. By extracting carbon dioxide directly from ambient air, DAC enables the provision of sustainable carbon feedstock for Power-to-X (PtX) applications, synthetic fuel production, and long-term carbon management strategies. In particular, the combination of DAC with high-temperature electrolysis technologies offers significant potential to produce renewable synthesis gas and downstream chemicals.
 

This work focuses on the development of a process model of a Direct Air Capture (DAC) plant in Aspen Plus. The model will represent the main process units as well as the associated mass and energy flows of a selected DAC process concept. The developed model will be used to analyze process performance under different operating conditions and to identify key factors influencing energy demand and overall system efficiency. Furthermore, it will provide a basis for future studies on the integration of DAC technologies into Power-to-X and carbon utilization pathways. Building upon the developed process model, selected operating strategies and process configurations
will be evaluated through sensitivity studies. In particular, the influence of operating pressure in key
process units will be investigated to assess its impact on process performance, energy consumption, and overall plant operation.
