Prospect of Post-Combustion Carbon Capture Technology and Its Impact on the Circular Economy

Abstract

The sudden increase in the concentration of carbon dioxide (CO2) in the atmosphere due to the high dependency on fossil products has created the need for an urgent solution to mitigate this challenge. Global warming, which is a direct result of excessive CO2 emissions into the atmosphere, is one major issue that the world is trying to curb, especially in the 21st Century where most energy generation mediums operate using fossil products. This investigation considered a number of materials ideal for the capturing of CO2 in the post-combustion process. The application of aqueous ammonia, amine solutions, ionic liquids, and activated carbons is thoroughly discussed. Notable challenges are impeding their advancement, which are clearly expatiated in the report. Some merits and demerits of these technologies are also presented. Future research directions for each of these technologies are also analyzed and explained in detail. Furthermore, the impact of post-combustion CO2 capture on the circular economy is also presented.

CO2 Post-combustion Capture: A Critical Review of Current Technologies and Future Directions

“…24 This method utilizes a liquid absorbent, or solvent, that can be regenerated through processes such as heating (temperature swing) or decrease of pressure (pressure swing) (Figure 4). 10,62 Absorption technologies are categorized into chemical absorption, which relies on acid−base reactions 2023 examines current technologies and future scenarios for capturing carbon from power plant emissions focus on CO 2 separation by absorption and its potential improvements Olabi et al 56 2022 discusses the potential, implications and benefits of post-combustion carbon capture technology emphasis on its impact on the circular economy Gizer et al 57 2022 explores recent developments in CO 2 capture and utilization focus on challenges, materials involved, and directions for future research Madejski et al 58 2022 provides a thorough analysis of various CO 2 capture methods emphasis on evaluating their application in modern energy technologies for reduced emissions Vaz et al 59 2022 examines various technologies for CO 2 capture for CCS focus on their application and impact within the energy sectors Song et al 60 2018 reviews alternative pathways for efficient CO 2 capture emphasis on the potential of hybrid processes to improve capture rates and reduce energy consumption between an alkaline solvent and CO 2 , and physical absorption, based on CO 2 solubility in an organic solvent influenced by temperature and pressure. 63,64 The process involves two phases with CO 2 being separated by the solvent in an absorption column, followed by CO 2 extraction in a regeneration column, and recycling the depleted solvent back to the absorber.…”

Mechanism and anti-corrosion measures of carbon dioxide corrosion in CCUS: A review

“…Post-combustion capture is to purify the flue gas first and then install a CO 2 separation and capture device in the flue gas channel ( Figure 2 ). 11 , 12 , 13 , 14 Among various methods, the alcohol amine method is susceptible to corrode carbon steel. , H 3 O + , and protonated amine are the root causes of the corrosivity of the ethanolamine solution.…”

Maximization of CO2 Capture Capacity Using Recent RUNge Kutta Optimizer and Fuzzy Model

“…Carbon capture is classified into three types: post-combustion, oxyfuel combustion, and pre-combustion [14,15]. Post-combustion is the most widely used CO 2 capture technology because it can simply be integrated into existing power facilities [16,17]. In this process, CO 2 is extracted from flue gas using a variety of processes, such as adsorption, absorption, membrane separation, hydrate-based separation, and cryogenic distillation.…”
