Improving efficiency and flow capacity of structured packings can help reduce absorption column investment costs in acid gas treatment and CO2 capture plants. IFPEN has recently patented a structured packing geometry with concepts that were applied to manufacture a number of packing elements with a geometric area of 200 m2/m3 named IFPACC 2X™. Hydrodynamic properties and effective area properties were evaluated in a 1 m diameter column. The performance results are compared to those of commercial packings. Relative to the Sulzer’s Mellapak 250.X, for example, this new packing can offer a 10% higher flow capacity with the same effective area yet with less geometric area.
