“…For the operating ranges investigated in this study, the fluxes of the individual components through the membrane can be considered as independent of each other. Hence, the permeances can be calculated using an Arrhenius approach according to:

true L = L_{\infty} \exp (- \frac{E}{RT})

“…Next to the pressure difference, the pressure ratio plays a dominant role in membrane gas separation , as the selectivity of a membrane cannot be exploited when the pressure ratio is not sufficiently high. Modern flat sheet thin‐film composite membranes developed for CO 2 separation exhibit CO 2 permeances in excess of 3 m 3 (STP) m −2 h −1 bar −1 with selectivity, expressed as the ratio of single gas permeance, of 60 to 50 at 20 to 25 °C , , . The membranes consist of porous support layers as well as gutter, separation and protection layers applied on top.…”

“…Although these membrane module types are quite well established, new module designs for flat sheet modules are desirable in order to transfer the superior flux performance characteristics of novel thin‐film composite membranes into practical applications. One of the applications for which these membranes were developed in the recent years is the separation of CO 2 from various gas sources as, e.g., flue gases or biogas . The former separation is thought to play an important role in the fight against global warming and in safeguarding the supply of carbon sources to the chemical industry .…”

Modern high‐performance flat sheet gas separation membranes exhibit high permeances as well as high selectivities, e.g., for CO2 separation. Novel membrane modules are desirable to transfer the intrinsic membrane performance to the process. The introduced module implements countercurrent flow, which allows for the best utilization of the required driving force, provided concentration polarization and pressure drops can be kept at bay. As such, it is different from established flat sheet modules for gas separation. The design features allow for straightforward scaling and easy adjustment to other operating conditions. During module development equation‐oriented modeling, computer‐aided engineering design and application of computational fluid dynamics for flow optimization were integrated. The prototype was investigated in a pilot plant. The experimental results reflected the simulation predictions and proved the validity of the module concept.

“…A remarkable feature of this membrane is the high CO 2 /N 2 selectivity at relatively high CO 2 permeance, which are favorable characteristics for an efficient membrane application [ 3 , 4 ]. Experiments at laboratory and pilot-plant scale have proven the good CO 2 separation characteristics of this membrane at pressures up to 10 bar [ 5 ]. Nevertheless, there are several processes, which require the separation of CO 2 from permanent gases and C 1 –C 3 hydrocarbons at higher pressures.…”

“…Additionally, a reliable model to predict the permeances has to be developed. At pressures up to 10 bar, the Free Volume Model (FVM) developed by Fang et al [ 8 ] has already been successfully applied for CO 2 separation from various gas mixtures with PolyActive™ TFCM [ 5 ], and for modeling of hydrocarbon separation [ 9 ]. The FVM has the advantage that parameters required for the description of mixed gas separation can be determined from single gas experiments.…”

Applicability of PolyActive™ Thin Film Composite Membranes for CO2 Separation from C2H4 Containing Multi-Component Gas Mixtures at Pressures up to 30 Bar

The PolyActive™ thin film composite membrane (TFCM) has already been successfully applied for CO2 separation tasks at feed pressures up to 10 bar. To investigate the applicability at higher pressures, measurements were undertaken with C2H4 containing gas mixtures with a composition comparable to the product stream of the oxidative coupling of methane process, as well as single gases up to a feed pressure of 30 bar. Furthermore, the permeances of the conducted gas mixture experiments were simulated. The results show a strong swelling influence of CO2 on the used membrane depending on the CO2 fugacity. This swelling effect leads to a pronounced decrease in selectivity. The observed membrane behavior at high pressures could not be predicted by the Free Volume Model (FVM). Two different simulations were conducted: one based on parameters calculated from single gas data measured at pressures up to 2 bar; and a second based on parameters calculated from single gas data measured at pressures from 2 to 30 bar. The two simulations differ in their prediction accuracy. However, they confirm that it is possible to predict the measured permeances in the pressure range up to an average CO2 fugacity of 6 bar.

considerable attention since 1980. [5] Despite the significant attention paid to the improvement of properties, most of the polymers studied did not exceed the Robeson upper bound, and none of them found use in the efficient separation system. [6] To obtain higher permeability and better selectivity, several approaches have been implemented, such as thermal rearrangement of the polymers, [7] formation of mixed matrix membranes (MMMs) by incorporation of metal-organic frameworks (MOFs), [8] covalent organic frameworks (COFs), [9] and other fillers into the polymer matrix. Every year, the drinking water demand increases, and thus energy-efficient water separation becomes more and more significant in terms of safe water supply in the world. Since we need to supply the world population with drinkable water from salty ocean, seas, and brackish water, water needs to be separated from its constituents such as salts, organic compounds, and bacteria. The primary membrane separation methods used widely for this purpose are forward osmosis (FO), reverse osmosis (RO), ultrafiltration (UF), nanofiltration (NF), microfiltration (MF), and electrodialysis reversal desalination (ERD). As a robust and low-energy-consuming technique, membrane distillation (MD) has recently received extensive attention. For this purpose, hydrophobic microporous polymeric membranes based on polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF), polypropylene (PP), etc., are implemented. In MD, a hot water stream circulates on the surface of the hydrophobic membrane, while only water vapor can pass through the porous structure of the membrane. The separated water vapor afterwards condenses on cold surfaces. Lee et al. reported that an electrospun perfluorooctyltriethoxysilane-coated titanium dioxide/polyvinylidene fluoride-co-hexafluoropropylene (F-TiO 2 /PVDF-HFP) membrane showed superhydrophobicity and a high water flux of 40 L m −2 h −1 compared to pristine PVDF membranes, [10] while the water flux of the PVDF nanofibrous hydrophobic membranes reinforced with fabric substrate was 49 kg m −2 h −1. [11] Being a 2D material, graphene oxide (GO) has attracted extensive attention in membrane science as a potential material due to its mechanical strength, [12] the possibility for property alteration by covalent and noncovalent chemical bonding, [13] and its cost-effective production. Recent works [14] show how GO incorporation affects the selectivity of polyimide-and Graphene oxide is functionalized with poly(2-diethylaminoethyl) methacrylate (PDEAEMA), and the resulting material is used as a selective layer of a thin-film composite membrane (TFCM). The polymer synthesis is carried out by surfaceinitiated atom transfer radical polymerization (SI-ATRP) from bulk and also from single-layer graphene oxide (GO). The polymer brushes synthesized by the "grafting from" method are characterized by size exclusion chromatography (SEC), nuclear magnetic resonance spectroscopy (NMR), Fourier-transform infrared (FTIR) spectroscopy, thermal gravimetric analys...
