“…Being more specific, suitable characteristics for these new solvents are based on obtaining high absorption rate and high CO 2 loadings. To reach this kind of aims several proposals have been developed mainly using ionic liquids and amines blends . These systems try to overcome negative effects of conventional solvents used at industrial scale.…”

Present research work analyses a new chemical solvents based on the use of two tertiary amines (dimethylethanolamine and diethylethanolamine) for carbon dioxide (CO 2) capture by chemical absorption taking into account the absorption behavior and the solvent regeneration degree. Regarding the first study, the absorption rate is related with the reaction mechanism at different CO 2 loading. Other type of influences such as the type and amine concentration, and gas flow rate fed to the contactor were studied. In relation with solvent regeneration, several experimental procedures have been employed in order to avoid the negative characteristics of loaded-solvent stripping. The results show the important weight of amines acidity constant upon the regeneration yield.

“…In the past two decades, membrane contactor performances have been investigated using different amine-based liquid absorbents. Several studies focused on MEA, − but ammonia, DEA, , MDEA, AMP, and other amine blends , have also been used, showing promising results in terms of CO 2 capture performance. Typically, porous membranes are used as an interface layer, as the membrane morphology is able to ensure a limited effect on the CO 2 overall mass transfer resistance, according to the resistance in the series model .…”

Phase change solvents represent a new class of CO 2 absorbents with a promising potential to reduce the energy penalty associated with CO 2 capture. However, their high volatility is a major concern for their use at the industrial scale. It is believed that membrane absorption offers a solution to overcome this issue, particularly if the membrane can prevent amine evaporation. In the present work a compatibility study is carried out in order to identify

“…Recently, important studies on carbon capture performance using ILs have been discussed in some reviews, , including interesting works with traditional ILs, as well as other new IL-based absorbents such as switchable ILs and functionalized ILs. Chen et al, Lu et al and Li et al confirmed that functionalized ILs exhibit a significantly high speed for CO 2 capture, excellent absorption capacity and easy regeneration; Lu et al and Xiao et al . proved that IL blending solvents yield high cycling CO 2 capacity, energy savings, good regenerability and especially a low viscosity; Privalova et al, Li et al and Zheng et al studied switchable ILs as promising IL-based solvents due to their low cost and ability to be recycled.…”

View full text Add to dashboard Cite

Post-combustion carbon capture (PCC) using membrane technology is a rising alternative to PCC processes, which is based on conventional equipment, such as CO2 absorptiondesorption in packed columns, to mitigate human-associated climate change. Research on CO2 capture system has been centered on improving the CO2 absorption process efficiency, while little attention has been devoted to the performance of the solvent regeneration technology.In this review, research development is focused on the performance of the CO2 desorption process using hollow fiber membrane contactors (HFMCs). The main impact factors in membrane contactor technology are presented, including solvent and membrane material selection, membrane module design, mass transfer correlations, operational issues, modeling and simulations. Each section has been discussed in terms of its current status while describing future challenges to improve the technology for its industrial implementation.
