TL;DR: In this article, it is shown that operating parameters of the process, in particular the desorber pressure, must be taken into consideration in the evaluation of new solvents.

TL;DR: In this paper, a new apparatus employing a modular, mechanically agitated gas-inducing crystallizer is used to demonstrate the capture of CO2 via hydrate crystallization, which enhances the contact of hydrate forming gases with water.

TL;DR: In this paper, a CO2-selective polyvinylamine/polyvinylalcohol (PVAm/PVA) blend membrane was investigated by experimental study and simulation with respect to process design, operation optimization and economic evaluation.

TL;DR: In this article, a series of experiments were conducted to examine the effects of flowing carbonated brine on well cements and the results showed that if the solution was pre-equilibrated with calcium carbonate, as would be expected in a limestone formation, there was no detectable attack.

TL;DR: In this article, mesoporous magnesium oxide (MgO) was synthesized using mesoporus carbon CMK-3 obtained from mesophorous SBA-15 as exotemplate, which was used as the structure-directing template and rice husk ash (RHA) as the silica source.

TL;DR: In this paper, a finite element model is applied to quantify the net change in permeability, the gas flow, and the resultant deformation in a prototypical coal seam under in situ stresses.

TL;DR: In this article, the authors evaluated ionic liquids as a potential solvent for post-combustion CO 2 capture and found that the energy demand of this 60 w% ionic liquid is slightly lower than that of the reference solution, resulting in possible energy savings between 12 and 16%.

TL;DR: Amine volatility is a key screening criterion for amines to be used in CO2 capture as discussed by the authors, and excessive volatility may result in significant economic losses and environmental impact, and also dictates the capital cost of the water wash.

TL;DR: In this article, the effects of high pressure CO2 exposure on fluid transport properties and mineralogical composition of two pelitic caprocks, a limestone and a clay-rich marl lithotype have been studied.

TL;DR: In this paper, a laboratory-scale system was built and operated to demonstrate the feasibility of catalytically reacting carbon dioxide (CO 2 ) with renewably-generated hydrogen (H 2 ) to produce methane (CH 4 ) according to the Sabatier reaction.

TL;DR: In this article, the authors investigate the casing-cement microannulus through core-flood experiments and show that the steel casing reacted to form abundant precipitates of mixed calcium and iron carbonate that lined the channels and almost completely filled a channel.

TL;DR: In this paper, Li4SiO4-based sorbents from fly ashes for CO2 capture at high temperatures have been developed, and three fly ash samples were collected and subjected to calcination at 950°C in the presence of Li2CO3.

TL;DR: In this article, the authors present the first operating experience with a 120kW chemical looping pilot rig with two different oxygen carriers, i.e., ilmenite, a natural iron titanium ore, and a designed Ni-based particle.

TL;DR: The CO 2 SINK pilot project at Ketzin is aimed at a better understanding of geological CO 2 storage operation in a saline aquifer as discussed by the authors, which consists of fluvial deposits with average permeability ranging between 50 and 100mDarcy.

TL;DR: A column of silica gel was employed to contact water with flue gas (CO 2 /N 2 ) mixture to assess if CO 2 can be separated by hydrate crystallization as mentioned in this paper.

TL;DR: In this article, Molten carbonate fuel cells (MCFCs) are considered for their potential application in carbon dioxide separation when integrated into natural gas-fired combined cycles.

TL;DR: In this paper, the carbon dioxide capture potential of amine amino acid salts (AAAS), formed by mixing equinormal amounts of amino acids; e.g. glycine, β-alanine and sarcosine, with an organic base; 3-(methylamino)propylamine (MAPA), was assessed by comparison with monoethanolamine (MEA), and with amino acid salt (AAS) from amino acid neutralized with an inorganic base; potassium hydroxide (KOH).

TL;DR: In this article, basalt samples from the United States, India, Iceland, and Canada were reacted with CO2 and CO2-H2S mixtures under supercritical CO2 (scCO2) conditions to study geochemical reactions resulting from injection of CO2 in such formations.

TL;DR: In this article, a parametric study was conducted on the 10kWth DFB facility at the University of Stuttgart, which consists of a bubbling fluidized bed carbonator and a riser regenerator.

TL;DR: The In Salah Gas Joint Venture CO 2 storage project has been in operation in Algeria since 2004 and is currently the world's largest onshore CO2 storage project as mentioned in this paper, where CO 2 is injected into the saline aquifer of a gas reservoir several kilometres away from the gas producers.

TL;DR: In this paper, a post-combustion carbonate looping process is based on the capture of carbon dioxide from the flue gases of an existing power plant in a circulating fluidized bed reactor (CFB) of calcium oxide (the carbonator) particles.
