Assessing absorption-based CO2 capture: Research progress and techno-economic assessment overview
Carbon Capture Science & Technology, 2023
Rapid industrial developments and rising population are mounting concerns, leading to increased greenhouse gas (GHG) emissions and resultant climate change. Therefore, to curb such drastic trends, it is necessary to adopt and develop a sustainable environment. Among the most effective ways to lower GHG emissions is carbon capture. Absorption is one of the most mature methods of reducing CO2 due to its high processing capacity, excellent adaptability, and reliability. This study aims to evaluate the most recent advancements in various CO2 capture techniques, with an emphasis on absorption technology. The techno-economic analyses of absorption-based CO2 capture processes were meticulously discussed. These include studies on solvent screening as well as techno-economic analysis methods. Economic estimators such as the payback period, rate of return and net present value are discussed. The research progress in absorption-based capture compared to other separation methods, is elucidated. Advances in the applications of various absorption solvents including aqueous, phase change solvents and deep eutectic solvents are presented. Finally, key recommendations are provided to tackle the challenges for efficient utilization of the absorption technique.
Research progress on CO2 capture technology by Chemical absorption method
The rapid growth of industrial activities in developing nations has led to a significant surge in global carbon dioxide (CO2) emissions, contributing to climate change accounts for over 70% of greenhouse gases responsible for the greenhouse effect. Industrial sources, including steel, cement, and chemical production, contribute about 25% of global emissions. Carbon capture technologies are crucial for mitigating these emissions. This review focuses on different studies on carbon capture by chemical absorption methods, focusing on Organic Amine Solution, Ammonia, and Sodium Hydroxide Solution.
Evaluation of Five Alternative CO2 Capture Technologies with Insights to Inform Further Development
Energy Procedia, 2017
The high cost of CO 2 capture using amine solvents from combustion sources such as natural gas-fired power plants remains a barrier to the adoption of CO 2 Capture and Storage (CCS) as a climate change mitigation measure. The objective of the work reported in this paper was to carry out a preliminary assessment of the potential of five alternative technologies suitable for postcombustion CO 2 capture from natural gas derived exhaust gases: • C O 2 permeable membranes • Molten Carbonate Fuel Cells • High-pressure solvent absorption from high-pressure exhaust gas from pressurised combustion / power generation • High-pressure solvent absorption supported by exhaust gas compression • Supersonic flow driven CO 2 deposition The results of the performance and cost evaluation for each technology are explained and the prospects for significant cost reduction compared to a state-of-the-art CO 2 capture process are discussed. Recommendations for further technology development activity are summarised in the conclusion of the paper.

The CO2CRC's UNO MK 3 process is a precipitating potassium carbonate process engineered to capture 90 % of carbon dioxide emissions from large scale emission sources such as power stations and other industrial sources. The UNO MK 3 is expected to have benefits in the following areas; • Low energy of regeneration (2-2.5 GJ/tonne of CO 2). • Low overall cost, which is expected to be greater than $20/tonne of CO 2 avoided less than competing amines. • Low volatility and environmental impact with low emissions, low toxicity and smaller carbon footprint. • Multi-impurity capture of CO 2 , SO x and NO x with linkage to the global potassium fertilizer chain. These key benefits of the UNO MK 3 process are being confirmed by the CO2CRC's work program, which combines fundamental research, process demonstrations and larger scale engineering applicable to capture from 500 MW power stations. Techno-economic results from this large scale engineering work program are presented and the systematic technology improvements discussed.
Carbon dioxide capture by absorption, challenges and possibilities
Chemical Engineering Journal, 2011
Challenges facing the use of reactive absorption as a technology for CO 2 capture on a global basis have been discussed. Special emphasis is placed on the reduction of energy requirement and environmental concerns. The relationships between fundamental properties of the absorbent system and the design, operation and performance of the absorption process are discussed on a fundamental basis, and pathways for searching new absorbent systems are identified. In particular, the use of new phase change systems is emphasized as a possibility for reducing the energy demand of these processes. Further, the need for an early investigation of the environmental properties of new absorbents is focused. Emissions of both absorbent and volatile degradation products must be below regulated norms, and methodologies for reducing these emissions to very low levels are suggested.

ANALYTICAL STUDY FOR COMMON CO 2 CAPTURE TECHNOLOGIES, 2020
The climate change problem as a result of the escalation of carbon dioxide emissions resulting from the combustion of organic materials is one of the most important problems that call for searching for an effective way to get rid of these emissions. CO 2 capture, utilization and storage has been considered as the first option to reduce the climate change phenomenon caused by the utilization of fossil fuels. There are many ways and strategies to capture of atmospheric carbon dioxide such as absorption and adsorption, membranes and chemical rings, moisture and the use of enzymes. This study aims to shed light on simulating the famous techniques used to get rid of carbon dioxide emissions in the atmosphere using the HYSYS program by taking an overview of previous research that dealt with carbon dioxide disposal technologies in order to facilitate the required modifications of these technologies to reach them To the highest possible levels of performance.
