摘要

The gas-liquid multiphase Eulerian computational fluid dynamics (CFD) model was used to investigate hydrodynamics and CO_2 removal efficiency of a pilot-scale amine absorber with structured-packing. The structured-packing was represented by a porous media zone having porous resistance, gas-liquid interfacial drag force, and liquid dispersion force. This study aimed to find a reasonable way to identify four modification factors of the Ergun coefficient that determine the hydrodynamic characteristics of structured-packing. The two modification factors (a and b) for porous resistance were mainly related to the liquid holdup (h_L) with respect to the liquid load. The other two factors (c and d) for gas-liquid interfacial drag force depended on the specific wet pressure drop (ΔP_(wet)/L) versus the gas load factor. The h_L and ΔP_(wet)/L increased in parallel with the increase of a and c, respectively, while the slopes of h_L and ΔP_(met)/L increased with b and d, respectively.
