Improvement of CO2 Adsorption Performance using TPMS-Based Flow Controllers

This study investigates the improvement of CO2 adsorption performance using a flow controller with a TPMS Gyroid structure. CO2 is a greenhouse gas that contributes to atmospheric pollution, and various adsorption technologies are being developed to address this issue. In this study, the TPMS structure was applied to control the inflow to a 13X-based CO2 filter, and the adsorption efficiency and pressure drop were measured with various unit cell sizes from 5 to 40 mm . The filter performance was evaluated based on the quality factor which which reflect the overall performance taking into account adsorption efficiency and pressure drop. The unit cell size of 10 had the best performance. The Gyroid structure can control velocity swirl and turbulence intensity of inflow, enhancing the interaction between the filter and CO2.
