The impact of binary water-CO2 isotherm models on the optimal performance of sorbent-based direct air capture processes.

First, an investigation of the co-adsorption of water and CO₂ onto a benchmark amine-functionalised adsorbent. Following on from this is a detailed process modelling and optimisation study of this sorbents performance in a direct air capture process. Next is a demonstration how the results are affected by the co-adsorption descriptions. Finally, a comparison between the modelled direct air capture process to existing and literature processes to benchmark the energy consumption of direct air capture.
