“…Membrane technology is primarily used to separate CO2/CH4 separation for natural gas treatment, H2/CO2 separation for hydrogen production in fuel cells, CO2/N2 separation in flue gas, and O2/N2 separation for the generation of oxygen-enriched air [1]. Polymer, ceramic, carbon, metal, and liquid are just a few materials that may be used to create membranes [2]. Different membranes have been researched for gas separation; polymeric nanoparticles are still the most typical because of their physical stability, processing capabilities, ease to use, and, most significantly, low cost [3,4].…”

This reaserch examines different analytical models based on the ideal case membrane structure that can use to evaluate gas penetration into mixed-matrix membranes (MMMs) loaded with non-partial fillers. Many models predicted CO2 permeance over PSF/FCTF-1(MMMs) and were compared to experimental results. The models were compared using standard criteria for validating models, such as the difference in penetrant permeability between the two phases ( and the absolute average relative error percentage. A comparison of those models was carried out based on the widely used model validation criteria, including a convenient measure of penetrant permeability difference between the two phases and absolute average relative error percent. Based on the typical values of morphological characteristics, it was determined that the following models fitted the data in the best order: Lewis‐Nielsen model< Pal model<Higuchi< Bruggeman model< Chiew and Gland < Maxwell model having AARE% values of 6.79, 8.45, 8.53, 10.23, 13.10, and 14.33, respectively. A scanning electron microscopy (SEM) examination of the cross-sectional image confirmed that the fillers were really ellipsoids scattered inside the matrix. The Maxwell-Wagner-Sillar model and the Lewis-Nielsen model were then used to evaluate the prolate effect, and the optimization curves of maximum packing () and shape factor (n) produced the least deviations. The AAR% variation was determined to be in the order of 0.01n 0.3, indicating the significance of the shape factor parameter in determining the accurate CO2 permeance.

“…It is important to undertake treatment, i.e. the removal of CO2 and other gaseous pollutants from natural gas, in order to fulfil the quality requirements specified by the majority of pipeline distribution companies, as stated in Table 1, because of this high concentration of CO2 in natural gas [2]. Acidic solutions resulting from the presence of CO2 are also corrosive [3].…”

Gas separation membranes are one of the most important processes in purifying natural gas. CO2 reduction of natural gas is essential for purifying the gas and increasing its calorific value. A covalent organic framework (COF) has been developed as a filler in mixed-matrix membranes (MMM) to separate gases. COF materials were chosen because of their economical rate, good thermal and chemical stability, and flexible microporous structure. Mixed matrix membranes (MMMs) have received significant interest for their improved permeability and selectivity in natural gas purification. The results of using COF combined with other chemicals added to MMM. It has been observed that CO2 permeability increases as the COF content in the MMM increases, which enhances the gas-separation performance of the MMM. This review evaluated and analyzed the current scientific and the technical breakthroughs in developing MMMs, especially the unique type of organic fillers, which has been the basis of numerous new research for CO2 separation.

“…The impact of competitive sorption and plasticization by CO 2 and H 2 O-induced free volume blocking was significantly greater, leading to fugacity-dependent permeabilities for CO 2 and CH 4 that were below those of the pure gas components. Relative to the simplified models, the new model predicts differences up to 2% and 18% in CH 4 recovery at low feed flow rates, and the difference in CO 2 removal can be as significant as 50% [ 24 ].…”

CO2 Plasticization Resistance Membrane for Natural Gas Sweetening Process: Defining Optimum Operating Conditions for Stable Operation

Membranes with a stable performance during the natural gas sweetening process application are highly demanded. This subject has been immensely explored due to several challenges faced by conventionally used polymeric membranes, especially the high tendency of plasticization and physical aging. In this study, polysulfone (PSf) hollow-fiber membrane was formulated and tested for its application in natural gas sweetening based on several compositions of CO2/CH4 mixed gas. The effects of operating conditions such as pressure, temperature and CO2 feed composition on separation performance were analyzed. The findings showed that the formulated membrane exhibited decreasing CO2 permeation trend with the increase in pressure. Conversely, the increase in operating temperature boosted the CO2 permeation. High productivity can be attained at higher operating temperatures with a reduction in product purity. Interestingly, since PSf has higher plasticization pressure, it was not affected by the change in CO2 percentage up to 70% CO2. The experimental study showed that the membrane material formulated in this study can be potentially evaluated at the field stage. Longer testing duration is needed with the real feed gas, appropriate pre-treatment based on the material limitations, and optimum operating conditions at the site to further confirm the membrane’s long-term lifetime, resistance, and stability.
