| Summary: | In this work, the effects of operative parameters on CH<sub>4</sub>, CO<sub>2</sub>, O<sub>2</sub>, and N<sub>2</sub> membrane gas separation for poly (4-methyl-1-pentane) (PMP) membrane modified by adding nanoparticles of TiO<sub>2</sub>, ZnO, and Al<sub>2</sub>O<sub>3</sub> are assessed and investigated. The operative parameters were type and percentage of nanoparticles, and cross membrane pressure. The membrane permeability and selectivity were selected as the responses and indexes of separation process performance. To design the experimental layout, design of experiment methodology (DoE) techniques were used. Further, the separation process was modeled and simulated using artificial intelligence (AI) methods. So, a robust black-box model based on radial basis function (RBF) network was developed and trained with the ability for predicting the performance of membrane process. The developed model could simulate the process and predict the permeability with R<sup>2</sup>-validation of 0.9. Finally, it was found that addition of nanoparticles and increasing the operative pressure had positive effects on membrane performance. Maximum permeability values for O<sub>2</sub>, N<sub>2</sub>, CO<sub>2 </sub>and CH<sub>4</sub> were 181.58, 52.09, 550.85, and 54.26, respectively. The maximum values of validation-R<sup>2</sup> of optimum structure for CO<sub>2</sub>/N<sub>2</sub> and CO<sub>2</sub>/CH<sub>4</sub> selectivity were 0.8697 and 0.7028, respectively. |
