Dataset of pressure drop and liquid holdup of ceramic structured column packings

This dataset contains experimental measurements on the hydraulic performance (pressure drop and liquid holdup) of six distinct ceramic structured packings (K125X, K125Y, K250X, K250Y, K350Y, and K450X). The data were obtained from tests conducted in a pilot-scale column (422 mm inner diameter) operated with an air/water system. Pressure drop across the packed bed was measured at various superficial gas velocities ranging from 0.7 to 5.3 m/s. Additionally, irrigated pressure drop and the associated liquid holdup were recorded over a range of liquid loadings between 6 and 120 m/h.本数据集包含六种不同陶瓷规整填料（ceramic structured packings）的水力性能实验测试数据，涵盖压降（pressure drop）与持液量（liquid holdup）两项指标。实验数据取自一套以空气-水为工质的中试塔装置（内径422 mm）内开展的测试：在0.7~5.3 m/s的空塔气速范围内，测定了填料床的压降；此外，在6~120 m/h的液体负荷区间内，同步记录了喷淋压降（irrigated pressure drop）及对应的持液量。
