Postcombustion carbon capture using a chemical absorbent is a promising technology to reduce CO₂ emission. However, the overall construction and operating costs remain a major challenge. In order to intensify the absorption process and to reduce these costs, a novel dynamic polarity structured packing (DP packing) with alternate patterns of surface polarity has been developed to enhance local macro-scale turbulence within the advanced viscous solvent to reduce the mass transfer diffusion resistance. Three DP structured packings that incorporate multiple polymeric materials were fabricated using three-dimensional printing technique and evaluated through parametric testing using a bench-scale integrated CO₂ capture unit with 76.2 mm ID absorber. At optimized operating conditions, the DP packing showed a relative 22.7% increase in absorption and 20.0% decrease in energy penalty.

在台式集成 CO2 捕获系统中使用 3D 打印动态极性填料增强 CO2 吸收

使用化学吸收剂的燃烧后碳捕获是减少CO ₂排放的有前途的技术。然而，总体建设和运营成本仍然是一个重大挑战。为了加强吸收过程并降低这些成本，已经开发了一种具有交替表面极性模式的新型动态极性规整填料（DP 填料），以增强先进粘性溶剂内的局部宏观尺度湍流，从而减少传质扩散反抗。使用 3D 打印技术制造了三种包含多种聚合物材料的 DP 规整填料，并通过使用小型集成 CO _{2的参数测试进行了评估}带有 76.2 毫米 ID 吸收器的捕获单元。在优化的操作条件下，DP 填料吸收增加了 22.7%，能量损失减少了 20.0%。
