A Comprehensive Review on Recent Advancements in Absorption-Based Post Combustion Carbon Capture Technologies to Obtain a Sustainable Energy Sector with Clean Environment

Abstract

CO2 capture, use, and storage have been identified as significant strategies for reducing greenhouse gas emissions induced by the usage of fossil fuels. The current review focuses on the concepts of post-combustion capture technologies based on absorption mechanisms. Among all other developed technologies, researchers have proposed absorption as the most mature carbon capture technology for industrial-scale application. Absorption-based carbon capture can be classified into chemical and physical absorption, and researchers have developed different solvents and absorbent materials to investigate their performance in CO2 capture. This paper comprehensively reviewed these established solvents and absorbents with their performance parameters in the CO2 absorption approach. Besides the improvement in widely applied absorbents such as amine-based absorbents, recently, researchers have been working to develop some advanced nanomaterials such as nanofluids and nano-emulsions. This review focuses on the application of such absorption mechanisms that can contribute to capturing CO2 in a compact, environment-friendly, and safe way. This paper also provides future research direction for further development in absorption-based CO2 capture.

Clean Energy from Poplar and Plastic Mix Valorisation in a Gas Turbine with CO2 Capture Process

“…Therefore, the heat available after the solvent regeneration was used to heat the air and the syngas before the combustion chamber. The CO 2 capture process is characterised by the L/G ratio, which is the ratio of the flow rate of chemical solvent used to the flow rate of the syngas/flue gas [35,36]. It is also characterised by the amount of specific heat energy required in the chemical solvent regeneration process [37].…”

Aqueous Potassium Salt of L-Cysteine as Potential CO2 Removal Solvent: An Investigation on Physicochemical Properties and CO2 Loading Capacity

“…Similarly, the reaction mechanisms of alkanolamines, such as MEA with CO 2 , also yields carbamate, as shown below. CO 2 absorption using amine-based solvents involves a series of reactions, as illustrated in Figures 3 and 4 [35]. In Figure 3, the amine acts as a weak base, which reacts with acidic CO 2 to form carbamate.…”

“…Recent studies have revealed the promising potential of amino acid salt (AAS) as an alternative solvent. AAS solvents exhibit identical amine functionality, high chemical reactivity with CO 2 , better resistance towards degradation, and low volatility, and they are environmentally friendly [31][32][33][34][35]. Another unique feature of AAS is its ability to form a solid precipitate during reaction with CO 2 .…”

Numerical simulation and performance optimization of a lead-free inorganic perovskite solar cell using SCAPS-1D

“…The consumption of power and energy is increasing with accelerated commercialization and industrialization [ 1 ]. The continuous utilization of conventional fuels such as natural gas, oils, hydrocarbon gas liquids, fossil fuels and the severe environmental effect for using these materials raises serious concerns about the research of alternate energy resources [ [2] , [3] , [4] ].…”
