Ionic liquid-based CO2 capture in power plants for low carbon emissions

Recycling CO2 from flue gas for CaCO3 nanoparticles production as cement filler: A Life Cycle Assessment

“…In this context, chemical absorption with monoethanolamine (MEA) is considered one of the most mature options to capture CO 2 from fossil fuel-fired flue gas streams [22]. Nevertheless, apart from MEA, ionic liquids (IL) have attracted significant attention for capturing CO 2 due to their advantages of low volatility, good dissolution properties and a high decomposition temperature [23]. Ma et al, 2018 [23] compared an ionic liquid (IL)-based carbon dioxide capture and storage processes with the MEA-based process.…”

Surface-Response Analysis for the Optimization of a Carbon Dioxide Absorption Process Using [hmim][Tf2N]

“…These values are obtained by fitting experimental solubility data, as shown in Table 5 for carbon dioxide [37]. (15) and (17). As provided in the work of Basha et al [37], good agreement is present between the experimental (reported in Shiflett and Yokozeki [55], Ren et al, [59] and Kumelan et al [57]) and predicted gas solubilities in the ionic liquid…”

“…These properties make it possible to reduce the losses of solvent and energy for regeneration [16,17]. Moreover, the solubility values of carbon dioxide in some ILs are similar to those in MEA solutions; conditions, the total required energy was 1.4 GJ/ton CO 2 , which is lower than that required by other capture technologies.…”

“…Additionally, no problems of solvent loss and corrosion were present. In another work, Ma et al [17] compared a capture process using [bmim][Tf 2 N] with one using MEA solution: the first case made it possible to save 30.01% of energy consumption and 29.99% of primary costs. Nguyen and Zondervan [40] compared the system capturing carbon dioxide from flue gas using MEA with one using [bmim][Ac], finding that the first was economically preferable at high flue gas flow rates and carbon dioxide contents.…”

PEST study of CO2 capture strategy from 2007 to 2018

“…The oxyfuel process, which has been investigated for the effectiveness of CO2 capture in a cement plant [11], [12], as well as research and reviews of different applications, compared to other capture methods [13], [14]. These methods have been used as a way to try to reduce CO2 emissions in many applications, but using different ways of applying them, such as using ionic liquids to capture and store CO2 in processes based on monoethanolamine in the combustion gases of a power plant, reducing the energy consumed by up to 30% and reducing CO2 emissions [15], as well as using an amine impregnated silicic acid compound as an adsorbent for CO2 capture, obtaining that the desorption activation energy was 335 Kj/mol and the estimated thermal regeneration load for the absorber was 53.29 kJ/mol CO2 [16], [17], as well as for the study of CO2 capture by carbontae loop in a 1 MW plant [18], analyzes the influence of crushing on the CO2 capture yield of CaO derived from natural limestone, for which, depending on the process used to obtain CaO, CaO will have less carbonation and will have greater crystallization or greater carbonation and less crystallinity of Cao, producing more CO2 emissions [19]. Although the method is very useful for reducing emissions, it is characterized by high energy consumption, with which research was conducted to use a hybrid configuration of the CO2 capture process after combustion in thermal power plants using aqueous monoethanolamine as a simulated absorbent in Aspen Plus [20].…”
