Adsorption Dataset on a Fully Packed Silica Gel Bed and three Z-Annular Flow Silica Gel Packed Beds

This dataset contains experimental primary adsorption data obtained from a fully packed bed (FPB) and three Z-annulus packed bed configurations. The three Z-annulus packed bed configurations are described by their annular dimensions as small (SAPB), medium (MAPB) and large (LAPB) corresponding to diametrical ratios (Do/Di) of 2, 2.35 and 3.08, respectively. The packed beds were filled with silica gel (Silicon Dioxide/SiO2) of particle size between 3.35mm-4.75mm.

The dataset contains raw temperature data from three mass transfer zones (MTZ) designated on the packed beds and their adjoining walls. The temperatures from the mass transfer zones and corresponding walls were obtaining using Omega K-type thermocouples. The inlet and outlet air conditions of temperature, velocity and relative humidity were obtained using Sentry ST732 Hotwire Anemometers and AZ 8829 Temperature and RH% data loggers. Inlet and outlet pressures were obtained using QEALY differential pressure meter connected to the Yokogawa MV2000 Data Logger. They were obtained as electrical pulses in Voltage and then converted into Pascal’s using manufacturer provided conversion factor. The inlet conditions were setup using a purpose-built air mixing box incorporating a convective fan and humidifier.

The dataset has spreadsheets captioned FPB Primary Data, LAPB Primary Data, MAPB Primary Data and SAPB Primary Data, respectively for two experimental test runs, Run 1 and Run 2. On each spreadsheet for each test run are the measured parameters in colour codes along with their units. Graphical plots of the inlet and outlet air temperature and relative humidity obtained from the AZ 8829 Temperature and RH% data loggers are also presented for each packed bed configuration and corresponding test run. From this primary data, the humidity ratio, amount of moisture removed (adsorption capacity), and pressure drops can be determined using appropriate correlations. The typical adsorption profile can also be determined using this data.

This dataset also includes spreadsheets on silica gel surface and pore property data from BET measurement obtained from Micromeritics ASAP 2020 (along with a summary report), specific heat capacity data from EXSTAR SII DSC 6220 differential scanning calorimeter (DSC), and thermal conductivity and resistivity data, volumetric specific heat capacity and thermal diffusivity data all obtained from KD2 Pro Thermal Analyser. Three analysis reports on true volume and density measurements from Quantachrome Ultra PYC 1200e gas pycnometer are also included.

本数据集包含了从全填充床（FPB）及三种Z形环状填充床配置（SAPB、MAPB、LAPB）中获取的实验性初级吸附数据。这三种Z形环状填充床配置分别以其环形尺寸小（SAPB）、中（MAPB）和大（LAPB）来描述，其直径比（Do/Di）分别为2、2.35和3.08。填充床由粒径介于3.35mm至4.75mm之间的硅胶（二氧化硅/SiO2）填充。数据集中还包含来自三个质量传递区（MTZ）及其相邻壁面的原始温度数据。质量传递区和相应壁面的温度是通过Omega K型热电偶获取的。进气和排气空气的温度、速度和相对湿度是通过Sentry ST732热线风速仪和AZ 8829温度及相对湿度%数据记录器获取的。进气和排气压力是通过连接到 Yokogawa MV2000 数据记录器的QEALY差压计获取的，它们以电压的形式作为电脉冲被记录，然后根据制造商提供的转换系数转换为帕斯卡。进气条件是通过一个专用的空气混合箱设置的，该混合箱内置了对流风扇和加湿器。数据集中包含FPB初级数据、LAPB初级数据、MAPB初级数据和SAPB初级数据四个电子表格，分别对应两次实验测试运行，即运行1和运行2。在每个测试运行的电子表格中，以彩色编码的方式展示了测量参数及其单位。同时，还展示了来自AZ 8829温度及相对湿度%数据记录器的进气和排气空气温度和相对湿度的图形曲线，这些曲线针对每种填充床配置及其相应的测试运行进行了呈现。通过这些原始数据，可以确定湿度比、去除的 moisture量（吸附容量）和压降，并利用相应的相关性确定典型的吸附曲线。此外，数据集还包括了来自Micromeritics ASAP 2020（附带总结报告）的硅胶表面和孔径属性数据（BET测量）、EXSTAR SII DSC 6220差示扫描量热计（DSC）的比热容数据、KD2 Pro热分析仪获取的热导率和电阻率数据、体积比热容和热扩散率数据。还包括了来自Quantachrome Ultra PYC 1200e气体密度计的三份关于真实体积和密度测量的分析报告。
