dc.description.abstractThis thesis investigates the use of custom 3D-printed structured packings to improve CO₂ absorption performance in a lab-scale column using water as the solvent. Two geometries were designed and fabricated (Design A: fine corrugation, 6.3 mm height; Design B: coarse pyramid-type, 17 mm height), and their specific surface area, porosity, and hydraulic behavior were characterized. Design A provided a much higher specific surface area (6.21×10² m²/m³) but lower porosity and consequently a higher estimated dry pressure drop (5.1×10² Pa/m), whereas Design B offered a lower surface area (2.32×10² m²/m³) with reduced pressure drop (~1.6×10² Pa/m). CO₂ absorption experiments over 10-minute runs showed moderate capture efficiencies, with Design A achieving about 4.6% and Design B slightly higher at 5.1%, indicating a trade-off between interfacial area and hydrodynamics. The results demonstrate that 3D printing enables tailoring of packing geometry either towards intensified mass transfer (Design A) or towards lower energy consumption and higher gas-handling capacity (Design B). Overall, the work highlights the potential of additively manufactured columns to support next-generation, more efficient CO₂ capture systems.
