(183a) Scale-up of Additively Manufactured Structured Packing Device for CO2 Capture

A new structured packing device that utilizes additive manufacturing has recently been designed at Oak Ridge National Laboratory. This device combines external gas-liquid contacting for mass transfer with internal coolant channels for heat transfer that results in process intensification for CO₂ capture with amine-based solvents. Previous generations of this device were manufactured and successfully tested at smaller scales with an 8-inch internal diameter column. Employing a new 12-inch-diameter column that was recently set up in our laboratories, we have demonstrated an increase in scale to 12-inches internal diameter. In the current scale-up study of this device, we examined the hydraulic properties of the corrugated geometry, the heat transfer performance under an air-water system, and the CO₂ capture performance with and without coolant in its internal cooling channels.
