使用空气从水中脱氧是在四种不同的规整填料中进行的。由于氧气很容易转移到空气中，因此传质的阻力位于液体侧。从这些实验中，测得的整体体积传质系数 (KLae) 等于液相的个体传质系数 (kLae)。使用 1992 年提出的模型估算界面面积 ae 的值，并推导液体的单独传质系数，并与 1985 年发表的第一个蒸馏塔规整填料模型中使用的渗透理论进行比较。结果发现，用于使两个系数相等的校正因子 CE 接近于 1。
Stripping of oxygen from water using air was performed in four different structured packings. Because the transfer of oxygen to air is easy, the resistance to mass transfer lies on the liquid side. From these experiments, the measured global volumetric mass-transfer coefficient (KLae) is equal to the individual mass-transfer coefficient of the liquid phase (kLae). The value of the interfacial area ae is estimated using a model proposed in 1992, and the individual mass-transfer coefficient of the liquid is deduced and compared to one based on the penetration theory used in the first model proposed for structured packing in distillation columns published in 1985. It was found that the correction factor CE used to equate both coefficients is close to unity.
