Composite hollow fiber membranes for CO2 capture

Post-combustion carbon capture technologies: Energetic analysis and life cycle assessment

“…capture. In this study we consider a composite polyvinylamine (PVAm)/Poly(phenylene oxide)(PPO) hollow fiber membrane as it has very high permeance and selectivity, which approach to industrialization (Sandru et al, 2010). Considering the low CO2 concentration in the flue gas and the limitation of the membrane materials reported, since using one stage membrane process cannot reach the assigned capture ratio (90%) and CO2 purity (95mol%), therefore a two-stage membrane system is preferred.…”

“…In this work, the membrane is modeled based on the experimental data from literature (Sandru et al, 2010), and is assumed to be prepared by coating a PVAm selective layer on the outer surface of PPO hollow fibers. The thickness of PVAm selective layer is estimated to be 1.1 μm, and the diameters of porous support of (PPO) hollow fibers are estimated as 0.5/0.34 (outer/inner) mm.…”

Relationship between polymer–filler interfaces in separation layers and gas transport properties of mixed matrix composite membranes

“…Since membrane permeance is inversely proportional to thickness, the resulting thinner composite material will have a higher permeance than the starting material [14]. Up to now, large efforts have been devoted to develop thin film composite membrane [15][16][17]. Combining with respective advantages of mixed matrix membrane and thin film composite membrane, mixed matrix composite membrane provides a realistic probability to improve performance of polymer membrane furthest.…”

Conceptual designs of hydrogen production, purification, compression and carbon dioxide capture

“…Some schemes such as a monoethanolamine (MEA) CO 2 scrubbing process and cardo polyimide hollow fiber membrane capture [6,7] are applied to reduce the emissions of greenhouse gases including methane and carbon dioxide. Koumpouras et al [8] introduced a low-temperature hydrogen production with in situ CO 2 capture.…”
