“…Periasamy Manikandan et al, studied the influence of Al 2 O 3 nanoparticles on mass transfer of a water-based nanofluid and reported the maximum CO 2 absorption enhancement at 0.6 vol% concentration of Al 2 O 3 nanoparticle [95]. Huang et al [96] and Park et al [97,98] added SiO 2 nanoparticles to a solution mixture of MEA, DEA, and Diisopropanolamine to evaluate its performance in CO 2 absorption in a stirred cell. They witnessed a reduction in the CO 2 absorption rate by increasing the nanoparticle concentration, which is believed to be related to the elasticity of the solution [99].…”

The continuous release of CO2 into the atmosphere as a major cause of increasing global warming has become a growing concern for the environment. Accordingly, CO2 absorption through an approach with maximum absorption efficiency and minimum energy consumption is of paramount importance. Thanks to the emergence of nanotechnology and its unique advantages in various fields, a new approach was introduced using suspended particles in a base liquid (suspension) to increase CO2 absorption. This review article addresses the performance of nanofluids, preparation methods, and their stability, which is one of the essential factors preventing sedimentation of nanofluids. This article aims to comprehensibly study the factors contributing to CO2 absorption through nanofluids, which mainly addresses the role of the base liquids and the reason behind their selection.

“…Pre-combustion CO2 capture is preferred for IGCC power plants since the gasification systems operate under high pressure, which make CO2 capture equipment much smaller in size compared with the post-combustion configuration. To remove all the carbon in syngas as CO2, water-gas-shift (WGS) reaction is employed to convert CO to CO2: [11] H2O + CO == CO2 + H2 + H (-41.2 kJ/mol) (a)…”

Compared with a pulverized coal power plant, the integrated gasification combined cycle (IGCC) has several advantages, including, among others better environmental performance and low CO2 capture cost. Hot/warm CO2 removal from syngas has also been a subject of research due to its potentially higher thermal efficiency. In this study, we proposed a generic adsorption based hot/warm CO2 removal process for IGCC power plants. Through analyses of the proposed generic process we have demonstrated that higher temperature of the hot/warm CO2 removal process will results in larger heat of adsorption, which in turns may increase energy consumption of the process. Under most of the operating temperature range, hot/warm CO2 removal process will lead to more electricity loss compared to the baseline Selexol process. However, if the adsorption step takes place at a temperature close to or higher than the highest steam temperature in steam cycle, our analysis indicates that the process may lead to minimal electricity loss. The study also provided some other insights into the pathways for hot/warm CO2 removal process to improve its energy performance through process and sorbent designs.

“…A surfactant that stabilizes the emulsion also affects the stability and CO2 absorption. A good surfactant should be soluble in the membrane phase only and not react with the extractant in the membrane phase to prevent the decomposition of the extractant and enhance the efficiency of the emulsion process [9]. Span-80 gives high relatively stable and easily demulsified emulsions and shows less resistance to mass transfer than other surfactant [10].…”

Emulsion liquid membrane (ELM) has been widely studied as an alternative method for amine absorption technology in the removal of acid gases such as carbon dioxide (CO2) and hydrogen sulphide (H2S). However, searching for stable ELM formulation with an enhanced CO2 absorption remains as challenge. Therefore, in this study, the aqueous solution containing a mixture of methyl diethanolamine (MDEA) and 2-amino-2-methyl-1-propanol (AMP) in sodium hydroxide (NaOH) solution was introduced as a dispersed phase, kerosene as continuous phase and Span-80 acts as a surfactant for the formation of water-in-oil (W/O) emulsion. In this study, the dispersed phase consists of 8% v/v MDEA and 4% v/v AMP and the continuous phase which contains 6% v/v Span-80 produced a stable emulsion and exhibited 65.2% of CO2 removal. This study indicates that the introduction of blended amine able to produce stable emulsion with an enhanced CO2 removal.
