“…The latter prediction is a direct consequence of the assumption made in equation (8) that the partial pressure of VOC in the air stream can be ignored. As is clear from Figure 10, this is an acceptable assumption for the toluene experiments, since a twofold reduction in air flow rate did not significantly change the toluene removal.…”

“…Progress has been made since that time, but [1][2][3] our basic understanding of membrane science has not changed. Although membranes with [4][5][6][7][8] useful selectivities to commercially interesting gas mixtures were known by the 1960s, the membranes were too expensive and the permeation rates were too low for large-scale applications. Both of these problems were solved in the 1960s and early 1970s by the developers of reverse osmosis membranes, who were the first to make defect-free, high-flux asymmetric membranes and incorporate large surface areas of these membranes into modules.…”

SUMMARYIn situ vacuum extraction, air or steam sparging, and vitrification are widely used methods of remediating soil contaminated with volatile organic compounds (VOCs). All of these processes produce a VOC-laden air stream from which the VOC must be removed before the air can be discharged or recycled to the generating process. Treatment of these off-gases is often a major portion of the cost of the remediation project. Carbon adsorption and catalytic incineration, the most common methods of treating these gas streams, suffer from significant drawbacks.Membrane Technology and Research, Inc. (MTR) proposes an alternative treatment technology based on permselective membranes that separate the organic components from the gas stream, producing a VOC-free air stream. The technology we propose to develop can be applied to off-gases produced by various remediation activities. The system will be skid-mounted and automatic for easy transportation and unattended operation. The system will remove the VOCs as a concentrated liquid phase and produce clean air (less than 10 ppmv VOC) for discharge or recycle and produce dischargeable water (less than 1 ppmw VOC).This report contains the results obtained during Phase I of a two-phase project. In Phase I laboratory experiments were carried out to demonstrate the feasibility of the proposed approach. In the subsequent Phase II, a demonstration system is to be built and operated at two field sites. The work performed in Phase I demonstrated that (1) membrane modules containing feed-side baffles have better VOC/air separation properties than conventional modules,hollow fiber contactors are very efficient stripping devices for the removal of VOC from water,the novel system design developed is capable of reducing the VOC concentration in remediation off-gas to 10 ppmv, while producing a concentrated VOC phase and dischargeable water containing less than 1 ppmw VOC, and (4) the membrane system is competitive with carbon adsorption if the VOC concentration in the remediation off-gas is 100 ppmv or higher.A design was prepared for a demonstration system able to treat 100 scfm off-gas, and two field sites have been identified. In the subsequent Phase II we propose to build the system and install it at the McClellan Air Force Base and the DOE Paducah site in Kentucky for field demonstrations.

“…The simulation of membrane based gas separations has been investigated for decades and the possibility to correctly predict the separation performances of a unit through a series of key equations and associated assumptions is abundantly documented (Bounaceur et al, 2006;Kaldis et al, 2000;Chowdhury et al, 2005;Coker et al, 1999;Matson, 1983;Zanderighi, 1996). Similarly to numerous studies in this field, a cross-plug flow model has been used for the simulations shown in this section.…”

Re´sume´-Proce´de´s membranaires pour le captage du dioxyde de carbone : e´tat de l'art et revue critique -Les proce´de´s de se´paration par membrane ont e´te´, dans un premier temps, rarement pre´conise´s pour le captage du dioxyde de carbone en post-combustion, les proce´de´s d'absorption gaz-liquide dans un solvant chimique e´tant conside´re´s comme la technologie la plus mature et la plus adapte´e pour assurer cette ope´ration. Une revue critique des possibilite´s et limites des membranes pour le captage du CO 2 par perme´ation gazeuse est pre´sente´e. Les performances de diffe´rents types de mate´riaux membranaires (polyme`res denses, mate´riaux inorganiques, matrices hybrides, membranes liquides) sont discute´es sur le plan de la se´lectiviteé t de la perme´abilite´, en prenant en compte les re´sultats expe´rimentaux les plus re´cents dans ce domaine. Les caracte´ristiques d'une unite´de perme´ation gazeuse mono-e´tage´e fonctionnant en re´gime permanent, de´termine´es par simulation, sont ensuite de´taille´es, en particulier par rapport aux contraintes de purete´et de de´pense e´nerge´tique de l'ope´ration, en lien avec les performances du mate´riau. Finalement, les possibilite´s des dispositifs membranaires multie´tage´s et des proce´de´s hybrides associant une unite´de perme´ation gazeuse et un autre proce´de´, encore peu e´tudie´es dans la litte´rature sont e´voque´es, ainsi que les besoins d'analyse technicoe´conomiques afin de mieux identifier la place et le roˆle optimal des membranes pour le captage du CO 2 .Abstract -Membrane Separation Processes for Post-Combustion Carbon Dioxide Capture: State of the Art and Critical Overview -Membrane processes have been initially seldom considered within a post-combustion carbon dioxide capture framework. More traditional processes, particularly gas-liquid absorption in chemical solvents, are often considered as the most appropriate solution for the first generation of technologies. In this paper, a critical state of the art of gas separation membranes for CO 2 capture is proposed. In a first step, the key performances (selectivity, permeability) of different membrane materials such as polymers, inorganic membranes, hybrid matrices and liquid membranes, including recently reported results, are reviewed. In a second step, the process design characteristics of a single stage membrane unit are studied. Purity and energy constraints are analysed as a function of operating conditions and membrane materials performances. The interest of multistage and hybrid systems, two domains which have not sufficiently investigated up to now, are finally discussed. The importance of technico-economical analyses is highlighted in order to better estimate the optimal role of membranes for CCS applications.
