“…In addition, the MEA:AMP mixture gave a better performance in removing CO 2 compared to AMP alone, which is may be due a synergistic effect between the two solutions. Blends of MEA and AMP was also investigated by Choi et al, 27 proving that the blends have a higher CO 2 loading than MEA and a higher reaction rate than AMP, thus indicating that the blends managed to combine the desirable characteristics of both individual solutions.…”

Veawab et al 23 Thitakamol and Veawab 24 MEA-AMP Absorption column Aroonwilas and Veawab 4 Veawab et al 23 Choi et al 27 Thitakamol Hybrid absorbents have the potential to exceed the performance of single absorbent as proven by Yeon et al 31 They used MEA and TEA as absorbents to remove CO 2 from flue gas in a hollow fiber module membrane contactor. For the hybrid absorbent containing 5wt% TEA and 5wt% MEA, the process operated for 80 h with a CO 2 removal efficiency of 90%-95%.…”

“…MEA solution has lots of advantages, such as strong alkaline, fast response rates with carbon dioxide and low cost ,but the reaction process was easy to generate a stable carbamate which resulted in a decreasing absorption, difficulty regeneration and strong corrosion phenomenon [2]. Adding piperazine (PZ) in MEA could improve the absorption and regeneration of absorbent [3,4]. According to lots of references, considering the effect of MEA absorption property in different ratable additives and the efficiency of the absorbent, the solution of 16% MEA+4% PZ was assumed as the efficient absorbent for carbon dioxide in this experiment.…”

Abstract. The experimental study on desorption for carbon dioxide is based on the phenomenon that pouring mints into coke can form coke fountain. In this study, the commonly used liquid monoethanolamine (MEA) was assumed as the absorbent for carbon dioxide, then the mint and its main compositions such as glucose, menthol, Arabic gum, gellan gum and Custer sugar were added into the absorbent rich liquid respectively. In addition, for studying the influence of the physical structure of the matter, chalk powder and activated carbon were also added separately. Under specific experimental conditions and different temperature, the effect on the desorption rate of different compositions and different materials were compared, through the determination of carbon dioxide desorption quantity in absorbent liquid. The results showed that the mint could effectively accelerate the desorption of carbon dioxide from the absorbing liquid rich, the main contributor is glucose. Contrasting the desorption results of mints ,chalk powder and activated carbon, it showed that physical structure of the carbon dioxide on the surface of the material also had great effect on the desorption rate, in addition to the influence of chemical composition.

“…However, the major drawback to conventional MEA solvent technologies are their high CO 2 capture costs resulting from the significant solvent regeneration energy demand, high capital costs of the absorption and regeneration equipment, and high operating costs. To overcome the challenges and drawbacks of the MEA-based capture process, researchers and technology developers have been working on the development of novel chemical solvent systems (Murai et al, 2013;Choi et al, 2009;Rochelle et al, 2011;Chowdhury et al, 2011;Mitsubishi Heavy Industries, 2010). These development activities focus on the reduction of the energy requirement and the total CO 2 capture cost.…”

a b s t r a c tThe successful deployment of any technology depends on many important factors. One of the critical ones that affect the success of post combustion CO 2 capture technologies is the ability to reduce the increase in cost of electricity associated with retrofitting the capture unit to electricity generating power plants.High capture costs associated with conventional MEA solvent processes has opened an opportunity for the emergence of many competing technologies aimed at reducing the cost of capture. This paper presents the technical and economic benchmarking of a polyethyleneimine (PEI)-based solid sorbent CO 2 capture process as compared to the conventional MEA solvent process, with both technologies applied to a natural gas combined cycle (NGCC) power plant.The results of this evaluation indicate that the PEI-based sorbent process requires approximately 25% less regeneration steam than the conventional MEA process primarily due to avoiding the energy demand required for heat of vaporization of water in the MEA process. The PEI solid sorbent based process results in approximately 6.3 power plant efficiency point reduction as opposed to an 8 efficiency points for the MEA based process. The design of the fluidized-bed absorption and regeneration reactors in the novel solid sorbent process result in significant reductions in capital costs (21% reduction compared to MEA). The economic evaluation shows that the PEI-based solid sorbent process offers attractive reductions in the cost of electricity and the CO 2 capture cost. The estimated cost of electricity, after adding the CO 2 capture process, is found to be 85 and 81.7 $/kWh for the MEA-based and PEI based process, respectively. Moreover, the cost of CO 2 avoided for both process is estimated to be 69.8 and 62 $/ton CO 2 for the MEA and PEI process, respectively.
