(378i) Development of Acoustic-Driven Packing Material a Novel Uky-Caer Technology for CO2 Capture
Authors
This presentation will cover the development of acoustic-driven packing material starting from proof of concept, bench scale testing with random packing material, and ending on the first prototype structured packing test. Lessons learned for future development will also be discussed such as the importance of impedance matching and variable frequency emitters. At 20 and 28 kHz, acoustic-driven packing material has been shown to provide up to a 20% relative increase in solvent absorption rate with 30 wt% monoethanolamine. Additionally, adding 1 wt% fine solids, â 40 µm, to the absorption solvent in combination with acoustic-driven packing material has been shown to further increase absorption rate by up to 40% over baseline testing. Acoustic amplitude was observed to be positively correlated with a minor increase in solvent absorption rate. This suggests that the smallest amount of power required to generate acoustic streaming in the solvent would be the most efficient choice in terms of power consumption optimization. Lastly, no decrease in performance has been observed when scaling from proof concept to prototype testing.
