A microbial carbonic anhydrase was immobilized onto the surface of hollow fiber membranes to enhance the absorption rate of carbon dioxide into an aqueous 30 wt% potassium carbonate solvent at pH 10–12. The performance of the immobilized enzyme was investigated over long time frames to determine the suitability of this approach for post-combustion carbon capture. The immobilized enzyme was able to maintain activity for up to 80 days at 25 °C even when initially exposed to pH 12, however lost activity rapidly when exposed to such high pH at 50 °C and subsequently was completely deactivated within 4 days. The effect of sulfur dioxide and nitric oxide that are present in post-combustion flue gas streams was investigated by contacting enzyme immobilized onto flat planar membrane coupons directly with the dry gases and with solutions containing the anions associated with the gases, namely sulfate, sulfite, nitrate and nitrite. The immobilized enzyme maintained at least 80% of its activity even in the presence of 200 mM of these anions or 500 ppm of the dry gases. Our findings indicate that the enzyme is not significantly affected by these toxic gases or their associated anions. Rather, the combination of high pH and ionic strength of the solvent at a high absorption temperature causes a reduction in the enzyme activity and affects the performance of the absorption process.

Sandra E. Kentish in OpenAIREThe emission of carbon dioxide into the atmosphere is recognized as a significant driver for climate change. Carbon capture and storage (CCS) techniques are efficient and effective ways to reduce these emissions to the atmosphere. However, the cost of any carbon capture technique has to be reduced to manageable levels before it can be deployed at an industrial scale. Several methods for capturing carbon dioxide, such as absorption, adsorption, membrane techniques and cryogenic separation have been proposed, of which absorption is the closest to commercial reality. Potassium carbonate is a good solvent for carbon dioxide capture because of its low regeneration energy, low degradation rates and low corrosivity. However, one shortcoming of potassium carbonate in CO2 absorption is that it has relatively slow reaction kinetics with CO2 resulting in the need for large absorption equipment. The most efficient method for improving the absorption kinetics is to add promoters into the potassium carbonate solutions. There have been a number of promoters studied over the last decades, including inorganic promoters such as arsenate, boric acid and vanadate, organic promoters such as different amines and amino acids, enzymatic promoters such as carbonic anhydrase and metal compounds mimicking carbonic anhydrase. In this paper, different promoters for CO2 absorption in potassium carbonate solutions are reviewed and their performance summarized. Additionally, a CO2 hydration promoting mechanism of deprotonation, followed by intermediate formation and then promoter regeneration is presented.

Sandra E. Kentish in OpenAIREMembrane gas solvent contactors have the potential to revolutionize carbon capture, because the technology combines the advantages of both membrane and solvent technologies. Here, an asymmetric composite poly dimethylsiloxane (PDMS) on porous polysulfone membrane contactor was studied for the desorption of CO2 from loaded 30 wt% monoethanolamine (MEA) solution. Importantly, this study investigated the performance of the contactor at temperatures where the MEA solution entered the contactor as a liquid and as a vapor. It was found that the PDMS contactor CO2 flux was comparable to other reported membrane contactors when the MEA solution was in the solvent phase, but when the feed was vaporized the CO2 flux increased by an order of magnitude. Similarly, the overall mass transfer coefficient had the same behavior, in that an order of magnitude increase was obtained when the MEA solution was above the boiling temperature. The CO2 permeability through the non-porous PDMS layer was calculated based on mass transfer correlations and the temperature trend was comparable to literature. This indicated that CO2 transport through the PDMS layer was the same for the range of temperature and phase conditions studied, and that the mechanism was based on CO2 transporting in the gas phase. Significantly high water fluxes were observed through the PDMS membrane, two orders of magnitude greater than CO2, which was comparable with other non-porous contactors. However, at 110 °C, the H2O/CO2 flux selectivity decreased to 14, indicative of the higher CO2 flux at that temperature because of the vapor feed.

Geoffrey W. Stevens in OpenAIREAbstract A protic ionic ethylenediamine liquid N,N-dimethyl-aminoethylammonium formate (DMEDAH formate) was evaluated for the removal of carbon dioxide from carbon dioxide and nitrogen mixed gas streams. This evaluation was conducted via a series of vapour–liquid equilibrium (VLE) experiments, wetted wall measurements and solvent contactor trials with the results compared to the performance of the industrial standard 30 wt% monoethanolamine (MEA). The VLE of the ionic liquid indicated that the sorption process included a chemical reaction component and is comparable to MEA. The mass transfer coefficient, calculated via the wetted wall column apparatus is an order of magnitude lower than MEA, which is likely due to the higher viscosity of the ionic liquid and its impact on carbon dioxide diffusivity. The solvent contactor trials indicated the solvent may be used in such an arrangement with good performance at low CO2 loadings, but would benefit from the use of alternative membrane materials.

Geoffrey W. Stevens in OpenAIREAbstractMembranes were manufactured using a novel plasma sputtering technique that rendered the surface hydrophobic. These membranes are cost effective compared to Teflon (polytetrafluoroethylene, PTFE) and allow for a greater selection of membrane alternatives. The nylon substrates used here were surface treated for 30 minutes at a power rating of 100 W to achieve an optimal surface contact angle of 151° and a surface fluorine concentration of 40%. Reductions in surface oxygen and carbon levels of the treated membranes suggested surface masking of the substrate, typical of sputtered surfaces. The breakthrough pressure of the membranes was found to be independent of the surface properties and was optimized at 200 W and 90 minutes of treatment. This suggests that penetration of the membrane pores by hydrophobic sputtered material improves the resistance to wetting. Membrane stripping experiments show that at elevated temperatures plasma sputtered nylon has increased mass transfer over a comparable PTFE membrane. Both membranes displayed signs of wetting as a result of elevated system temperature which causes a reduction of the solvent surface tension, that contributes to wetting.

Geoffrey W. Stevens in OpenAIREAbstractMembranes were manufactured using a novel plasma sputtering technique that rendered the surface hydrophobic. These membranes are cost effective compared to Teflon (polytetrafluoroethylene, PTFE) and allow for a greater selection of membrane alternatives. The nylon substrates used here were surface treated for 30 minutes at a power rating of 100 W to achieve an optimal surface contact angle of 151° and a surface fluorine concentration of 40%. Reductions in surface oxygen and carbon levels of the treated membranes suggested surface masking of the substrate, typical of sputtered surfaces. The breakthrough pressure of the membranes was found to be independent of the surface properties and was optimized at 200 W and 90 minutes of treatment. This suggests that penetration of the membrane pores by hydrophobic sputtered material improves the resistance to wetting. Membrane stripping experiments show that at elevated temperatures plasma sputtered nylon has increased mass transfer over a comparable PTFE membrane. Both membranes displayed signs of wetting as a result of elevated system temperature which causes a reduction of the solvent surface tension, that contributes to wetting.

Sandra E. Kentish in OpenAIREAbstract CO 2 capture and storage has gained widespread attention as an option for reducing greenhouse gas emissions. Chemical absorption and stripping of CO 2 with hot potassium carbonate (K 2 CO 3 ) solutions has been used in the past, however potassium carbonate solutions have a low CO 2 absorption efficiency. Various techniques can be used to improve the absorption efficiency of this system with one option being the addition of promoters to the solvent and another option being an improvement in the mass transfer efficiency of the equipment. This study has focused on improving the efficiency of the packed column by replacing traditional packings with newer types of packing which have been shown to have enhanced mass transfer performance. Three different packings (Super Mini Rings (SMRs), Pall Rings and Mellapak) have been studied under atmospheric conditions in a laboratory scale column for CO 2 absorption using a 30 wt% K 2 CO 3 solution. It was found that SMR packing resulted in a mass transfer coefficient approximately 20% and 30% higher than that of Mellapak and Pall Rings, respectively. Therefore, the height of packed column with SMR packing would be substantially lower than with Pall Rings or Mellapak. Meanwhile, the pressure drop using SMR was comparable to other packings while the gas flooding velocity was higher when the liquid load was above 25 kg m −2 s −1 . Correlations for predicting flooding gas velocities and pressure drop were fitted to the experimental data, allowing the relevant parameters to be estimated for use in later design.

Gabriel da Silva in OpenAIREAbstract The absorption kinetics of carbon dioxide (CO 2 ) into amino acid promoted potassium carbonate (K 2 CO 3 ) solutions has been studied using a wetted-wall column. Experiments were conducted under conditions resembling those found at industrial CO 2 capture plants including concentrations up to 2.0 M and temperatures from 40 to 82 °C. Results presented here show that the addition of 1.0 M glycine, sarcosine and proline accelerates the overall rate of absorption of CO 2 into a 30 wt% K 2 CO 3 solvent by a factor of 22, 45 and 14, respectively, at 60 °C. The Arrhenius expressions for the reaction between CO 2 and aforementioned amino acids are k 2-Gly [M −1 s −1 ] = 1.22 × 10 12 exp(−5434/ T [K]), k 2-Sar [M −1 s −1 ] = 6.24 × 10 10 exp(−1699/ T [K]) and k 2-Pro [M −1 s −1 ] = 1.02 × 10 11 exp(−2168/ T [K]) where the activation energies are 45.2 kJ mol −1 , 14.1 kJ mol −1 and 18.0 kJ mol −1 , respectively. The reaction order with respect to glycine is found to be 1, while the reaction order with respect to sarcosine and proline is observed to be in the range of 1.3–1.6 and 1.2–1.3, respectively.

Geoffrey W. Stevens in OpenAIREAbstract The energy penalty is a primary limitation for the implementation of the aqueous solvents for large-scale post-combustion CO2 capture processes. In this study, a novel aqueous-based phase change solvent, composed of potassium glycinate (GlyK, reactive species), water (H2O, solvent) and dimethylformamide (DMF, antisolvent) was developed to improve the energy efficiency of CO2 capture. To examine the role of the antisolvent, a series of aqueous-based amino acid solvents (GlyK-X) with different DMF:H2O (X) volume ratios was prepared, fully characterized and assessed. It was observed that a CO2-free phase appeared at the top of the aqueous-based amino acid GlyK-X solvents after CO2 absorption which can be easily separated and recycled to the absorption column and save energy. The results showed that the GlyK-60 solvent with DMF:H2O volume ratio of 60:40 had a very high CO2-free phase volume (63%). Moreover, the GlyK-60 solvent exhibited 26.1% (0.433–0.546 mol CO2/mol GlyK) enhancement in CO2 absorption capacity, 38.5% (130–80 min) decrease in regeneration time and 59.1% reduction in relative heat duty compared to the conventional aqueous GlyK solvent. Overall, the outcomes confirmed that the aqueous-based phase change GlyK-60 solvent is a viable solvent option for large-scale CO2 capture with extra-low energy consumption and a key to the success of Paris Climate Accord.

It was observed that a CO2-free phase appeared at the top of the aqueous-based amino acid GlyK-X solvents after CO2 absorption which can be easily separated and recycled to the absorption column and save energy. The results showed that the GlyK-60 solvent with DMF:H2O volume ratio of 60:40 had a very high CO2-free phase volume (63%). Moreover, the GlyK-60 solvent exhibited 26.1% (0.433–0.546 mol CO2/mol GlyK) enhancement in CO2 absorption capacity, 38.5% (130–80 min) decrease in regeneration time and 59.1% reduction in relative heat duty compared to the conventional aqueous GlyK solvent. Overall, the outcomes confirmed that the aqueous-based phase change GlyK-60 solvent is a viable solvent option for large-scale CO2 capture with extra-low energy consumption and a key to the success of Paris Climate Accord.

Geoffrey W. Stevens in OpenAIRECurrently, a large proportion of global fossil fuel emissions originate from large point sources such as power generation or industrial processes. This trend is expected to continue until the year 2030 and beyond. Carbon capture and storage (CCS), a straightforward and effective carbon reduction approach, will play a significant role in reducing emissions from these sources into the future if atmospheric carbon dioxide (CO2) emissions are to be stabilized and global warming limited below a threshold of 2 °C. This review provides an update on the status of large scale integrated CCS technologies using solvent absorption for CO2 capture and provides an insight into the development of new solvents, including advanced amine solvents, amino acid salts, carbonate systems, aqueous ammonia, immiscible liquids and ionic liquids. These proposed new solvents aim to reduce the overall cost CO2 capture by improving the CO2 absorption rate, CO2 capture capacity, thereby reducing equipment size and decreasing the energy required for solvent regeneration.
