Structured packings are widely used in oil & gas industries, as they can provide substantial surface area and high void fraction, thus enabling high mass transfer efficiency at a low pressure drop. This study investigates the hydrodynamic performance of two structured packings, namely, Mellapak 250Y and Montzpak B1−500. The pressure drop and liquid distribution are reported for a column of 200 mm diameter and 400 mm packing height. Wire-mesh sensor (WMS) is used to monitor the liquid distribution at the location of packing transitions. Packing replicas manufactured using a Fused Deposition Modelling (FDM) 3D printer is compared with commercial packings in terms of pressure drop and liquid distribution. A Computational Fluid Dynamics (CFD) model is initially validated using experimental data and then is used to investigate the effects of packing features, such as plate thickness, packing corrugation angles, holes, and packing transitions. The 3D-printed replicas show consistent performance compared to the commercial packings but can provide more information when measuring liquid distribution. The methodology and results discussed in this study can provide in-depth insights into the performance of structured packings, which is of critical importance when optimising packing parameters and testing new designs.

结构填料被广泛用于石油和天然气行业，因为它们可以提供较大的表面积和高空隙率，因此在低压降下具有很高的传质效率。这项研究调查了两种结构填料，即Mellapak 250Y和Montzpak B1-500的流体力学性能。报告了直径为200 mm，填充高度为400 mm的色谱柱的压降和液体分布。丝网传感器（WMS）用于监视填料过渡位置处的液体分布。使用融合沉积模型（FDM）3D打印机制造的包装副本在压力降和液体分布方面与商用包装进行了比较。首先使用实验数据验证计算流体动力学（CFD）模型，然后将其用于研究填料特征（如板厚，填料波纹角，孔和填料过渡）的影响。与商业包装相比，3D打印的复制品表现出一致的性能，但在测量液体分布时可以提供更多信息。本研究中讨论的方法和结果可以提供对结构包装性能的深入了解，这对于优化包装参数和测试新设计至关重要。与商业包装相比，3D打印的复制品表现出一致的性能，但在测量液体分布时可以提供更多信息。本研究中讨论的方法和结果可以提供对结构包装性能的深入了解，这对于优化包装参数和测试新设计至关重要。与商业包装相比，3D打印的复制品表现出一致的性能，但在测量液体分布时可以提供更多信息。本研究中讨论的方法和结果可以提供对结构包装性能的深入了解，这对于优化包装参数和测试新设计至关重要。
