CO2-selective membranes for hydrogen production and CO2 capture – Part I: Membrane development

Extended flue gas trials with a membrane-based pilot plant at a one-ton-per-day carbon capture rate

“…Research programs around the world have been operating field trials with carbon capture or related membrane systems [4][5][6][7][8][9][10][11]. For example, as part of a European Union project, small membrane modules developed by NTNU in Norway were recently tested at a coal power plant in Portugal.…”

Recent developments in membranes for efficient hydrogen purification

“…For hydrogen purification from shifted synthesis gas, CO 2 -selective membranes are reverse selective membranes where larger CO 2 molecule can permeate faster than smaller H 2 molecule [2,14]. In order to achieve CO 2 preferential permeation, the membrane should possess enough strong CO 2 affinity.…”

“…In addition, hydrogen is an important feedstock with increasing demands for the chemical industries. Hence, about 53 million metric tons of hydrogen worldwide was produced annually, and the hydrogen market valued at $88 billion in 2010 [2].…”

“…Therefore, hydrogen purification is essential to satisfy the purity requirements of various potential applications, and it is an important issue for efficient hydrogen supply. Moreover, H 2 -CO 2 separation is a key process in pre-combustion CO 2 capture for integrated gasification combined cycle (IGCC) power plants, even though the required hydrogen purity for subsequent electricity generation is generally lower than that of aforementioned applications [2]. It should be noted that hydrogen possesses a very low volumetric energy density despite its aforementioned advantages over conventional liquid fuels.…”

Parametric analysis and potential prediction of membrane processes for hydrogen production and pre-combustion CO 2 capture

“…According to previous studies, most of the membranes reported were measured as spiral-wound modules that can be applied over a high-pressure range (Lin et al, 2014;Schwinge et al, 2004). Models describing the spiral-wound membrane have been commonly used in previous studies, such as the cross-flow model, the cocurrent flow model and the countercurrent flow model.…”
