In this second part, a validation exercise is conducted to investigate the accuracy of the multicontinuum approach in estimating the permeation capacity of membranes used for the filtration of oily-water systems. Comparisons with the experimental works found in the literature reveals that the multicontinuum approach is quite accurate and show excellent match. Although the comparisons with the experimental data have been with respect to macroscopic integral variables, like the rejection capacity of membranes, the multicontinuum approach provides myriad information about the permeation process that have neither been presented nor even measured. Such detailed information has been highlighted in two examples. Details about which of the oil continua is going to be rejected or permeated through which porous membrane continuum are obtained. Furthermore, the flux of each oil continuum through every porous membrane continua is likewise obtained. These informations are then lumped to calculate the rejection capacity of membranes. © 2017 American Institute of Chemical Engineers AIChE J, 2017

解决跨薄的平膜的油水系统过滤问题的多连续方法:II。验证和示例

在第二部分中,进行了一项验证性练习,以研究多连续谱方法在估计用于油水系统过滤的膜的渗透能力方面的准确性。与文献中的实验作品进行比较表明,多连续谱方法非常准确,并且显示出极好的匹配性。尽管与实验数据的比较是针对宏观积分变量(如膜的排斥能力)进行的,但多连续谱方法提供了有关渗透过程的大量信息,这些信息既未提出,也未进行测量。这样的详细信息已在两个示例中突出显示。关于哪个油连续体将被排斥或渗透的细节,通过该多孔连续体获得。此外,同样获得每个油连续体通过每个多孔膜连续体的通量。然后将这些信息集中起来,以计算膜的截留能力。©2017美国化学工程师学会AIChE的Ĵ,2017年
