There are several technological options for post-combustion CO 2 capture. Absorption with novel solvents, adsorption, conversion of CO 2 into chemical products, calcium looping, and membrane technology are the main alternatives to the conventional absorption process based on amines. In this review, an overview of these technologies is presented and the role that membranes play is evaluated considering two approaches: (i) processes based on selective membranes (gas permeation and supported liquid membranes), and (ii) processes based on non-selective membranes (membrane contactors). The process performance demonstrated by recent research shows that membrane technology can fulfi ll the technical requirements for CO 2 capture but a closer interaction with the industrial partners and membrane manufacturers is needed to implement this technology in the industry.

“…To date, a body of models tentatively describes the existence of strong couplings between mechanical, thermal and diffusive phenomena occurring in polymeric materials in fluid transport, with the additional difficulty in modeling the state of the fluid within the polymer. Theoretical descriptions of these coupling phenomena are based on empirical or thermodynamic interpretations, as given in the selected open literature [25][26][27][28][29][30][31][32][33][34][35][36][37].…”

-The work aims at identifying the key diffuso-elastic couplings which characterize a numerical tool developed to simulate the irreversible 'Explosive Decompression Failure' (XDF) in semi-crystalline polymer. The model proposes to predict the evolution of the gas concentration and of the stress field in the polymer during the gas desorption [DOI: 10.10161j.compositesa.2005.05.021]. Main difficulty is to couple thermal, mechanical and diffusive effects that occur simultaneously during the gas desorption. The couplings are splitting into two families: -indirect coupling (i.e., phenomenology) that is state variables (gas concentration, temperature, and pressure) dependent; -direct coupling, (i.e., diffuso-elastic coupling) as polymer volume changes because of gas diffusion. The numerical prediction of the diffusion kinetics and of the volume strain (swelling) of PVF 2 (polyvinylidene fluoride) under CO 2 (carbon dioxide) environment is concerned. The prediction is carried out by studying selected combinations of couplings for a broad range of CO 2 pressures. The modeling relevance is evaluated by a comparison with experimental transport parameters analytically identify from solubility tests. A pertinent result of the present study is to have demonstrated the non-uniqueness of the coefficients of diffusion (D) and solubility (S g ) between the diffuso-elastic coupling (direct coupling) and indirect coupling. Main conclusion is that it is necessary to consider concomitantly the two types of couplings, the indirect and the direct couplings.Re´sume´-Cine´tique de diffusion et comportement diffuso-me´canique du syste`me dioxide de carbone / polyfluorure de vinylide`ne sous de´compression explosive de gaz : identification des couplages diffuso-e´lastiques majeurs par confrontation nume´rique et expe´rimentale -Cette e´tude a pour objectif d'identifier les couplages diffuso-e´lastiques majeurs qui entrent en jeu dans une Oil & Gas Science and Technology -Rev.

“…17 The NELF model is able to represent the solubility of gases and vapors in amorphous glassy polymers; the lattice fluid model is combined with the simple transport model, as done previously by others. [20][21][22][23][24][25][26][27] The diffusivity of the penetrants has to be analyzed too and described by an appropriate transport model. The diffusional behavior of the penetrant in the polymer matrix is related to the penetrant size and the diffusion sites available.…”

The influence of moisture content on the polymer structure of polyvinyl alcohol in dispersion barrier coatings and its effect on the mass transport of oxygen

This paper presents a study of the effect of moisture on the gas permeability of polyvinyl alcohol (PVOH) and PVOH-kaolin dispersion barrier coatings. The oxygen permeability was measured at different humidity levels, and the material properties were characterized under the same conditions: polymer crystallinity, kaolin concentration, and kaolin orientation were all evaluated. The experimental results revealed that the water plasticizes the PVOH material of the coatings, and the presence of kaolin filler is unable to affect such behavior significantly. The PVOH crystallinity was affected drastically by the humidity, as water melts polymer crystallites, which is a reversible process under removal of water. The permeability data were analyzed using a thermodynamicbased model able to account for the water effect on both the solubility of the gas and the diffusivity coefficients in the polymer and composite. The results showed good agreement between the model's predictions and the experimental data in terms of the overall permeability of the material.
