Water_Permeation_Data_Nafion_Membrane

The provided Excel-files contain the steady-state water permeation data at different operating conditions in a membrane humidifier. The membrane humidifier "Module 1" is a flat-sheet, single-layer membrane module in a counter-flow configuration. In the "Analysis" tab the calculated results for the four gas streams, Wet Inlet, Wet Outlet, Dry Inlet, and Dry Outlet are presented. From these values the water recovery rate in the membrane module, the water flux, and the overall permeance was calculated. The tab "Averaged raw data" shows the averaged measurement values of the experimental setup that are used for the calculations in the "Analysis" tab. Measurement values were taken every second and each test point was measured for at least 30 minutes after reaching steady-state conditions. The data was then averaged over the measurement time at steady-state. Since the values for water permeation varied for different membrane samples, multiple test runs with different membrane samples were averaged. The tab "Averaged raw data" shows the averaged values for these different test runs. For Nafon 211, the data shows the average of two different membrane samples and one test run with each sample. Three different samples and a total of seven test runs are averaged for Nafion 212 and two samples and a total of four test runs are averaged for Nafion 115. The tab "Properties" contains coefficients for the calculation of the saturation vapor pressure with the Wagner equation, the coefficients for the calculation of the enhancement factor and compressibility, and the molar masses. The other tabs show diagrams of the overall permeance and water flux for different operating conditions.

所提供的 Excel 文件包含了在不同操作条件下膜加湿器中的稳态水渗透数据。膜加湿器“模块 1”为对置流配置下的单片、单层膜模块。在“分析”标签页中，展示了四个气流的计算结果，包括湿进料、湿出料、干进料和干出料。根据这些值，计算了膜模块中的水回收率、水通量和整体渗透率。在“平均原始数据”标签页中，显示了用于“分析”标签页中计算的实验装置的平均测量值。测量值每秒记录一次，且在每个测试点达到稳态条件后至少测量了 30 分钟。随后，对稳态条件下的测量时间进行了平均值计算。由于不同膜样品的水渗透值存在差异，因此对多个不同膜样品的测试运行进行了平均。在“平均原始数据”标签页中，展示了这些不同测试运行的平均值。对于 Nafion 211，数据展示了两个不同膜样品的平均值以及每个样品的一个测试运行的平均值。Nafion 212 有三个不同样品，共计七个测试运行的平均值，而 Nafion 115 则有两个样品，共计四个测试运行的平均值。在“属性”标签页中，包含了使用 Wagner 方程计算饱和蒸汽压的系数、计算增强因子和压缩性的系数以及摩尔质量。其他标签页展示了不同操作条件下的整体渗透率和水通量图。
