📄 Abstract（原文）
Abstract Deep eutectic solvent (DES)‐based systems have recently emerged as promising alternatives to conventional liquid sorbents for CO 2 capture due to their tunable properties and potential for enhanced mass transfer. In this work, two DES‐based slurry systems previously developed for CO 2 capture, one aqueous and one non‐aqueous, were further evaluated under conditions relevant to industrial operation. Their performance was investigated using pure CO 2 as well as the CO 2 /N 2 and CO 2 /CH 4 gas mixtures up to 1.5 MPa to elucidate the effects of operating pressure and non‐reactive gas components typically present in industrial gas streams. It shows that the species other than CO 2 revealed a negligible impact on CO 2 uptake. Subsequently, to assess the practical applicability of the slurry systems, CO 2 capture was performed using conditioned flue gas after the biomass combustion at the Smurfit WestRock industrial site in Piteå, Sweden. The slurries demonstrated stable performance, with the aqueous slurry exhibiting higher uptake.
