“…The MDEA/PZ blend was investigated by Closmann et al (2009), Closmann (2011, and Voice et al (2013) in order to replace 30% MEA. Experiments for 7 m MDEA/2 m PZ were conducted at temperatures from 100 to 150 • C with CO 2 loading from 0 to 0.43 mol CO 2 /mol alkalinity.…”

“…New designs have been proposed to study solvent degradation during CO 2 capture by chemical absorption process. For example, a system called Integrated Solvent Degradation Apparatus (ISDA) has been reported to study both oxidative and thermal degradation cycles during CO 2 capture . Absorber/stripper configurations have been integrated in a single experimental apparatus in order to observe and identify secondary effects produced by CO 2 capture.…”

“…HTCS consists of an oxidative reactor operating at 35–45°C where amine solvents were contacted with 0.5% CO 2 in air. The solution was pumped from the oxidative reactor to a plate‐and‐frame cross‐exchanger following by a plate‐and‐frame trim heater where solvents were exposed to higher pressure (20 bar) and temperature (150°C) …”

Carbon dioxide capture and storage (CCS) technologies have been proposed as a promising alternative to reduce CO 2 emissions from fossil fuel power plants with post-combustion capture. Absorption by aqueous amine-solutions is considered the most mature and industrially developed technology for post-combustion capture. One of the most signifi cant issues hindering a large deployment of this technology is potential amine degradation. Amines degrade in presence of O 2 , CO 2 , NO x , SO 2 , and heat resulting in solvent loss, equipment corrosion and generation of volatile degradation compounds. Two types of degradation have been identifi ed in the literature, namely oxidative and thermal degradation. A review of the amine-based solvents, its main degradation products, the apparatus and analytical methods most widely used, as well as the mechanism proposed and kinetic studies are presented and discussed here. Moreover, amines emissions from CO 2 capture units can react in the atmosphere via photo-oxidation and also via NO X reactions to give nitrosamines and nitramines, which are potentially harmful to the human health and the environment. A discussion of the recent works on atmospheric degradation of amine solvents is also included in this review.

“…Voice et al . (2013) studied the amine degradation at high temperature and measured the influence of diphosphonic acid (HEDP) and diethylenetriamine penta (acetic acid) (DTPA) as additives to inhibit oxidative degradation. Their results indicated that AMP, PZ and 2MPZ showed significant resistance to the degradation at temperature less than 150°C.…”

Post-combustion CO 2 capture from the power and industrial sectors has gained widespread attention due to its ability to retrofit easily with newly installed and existing plants. This state-of-the-art, updated review provides an overview of technical issues in post-combustion CO 2 capture related to process performance, energy requirements for CO 2 capture, and inconsistencies in the prediction of CO 2 capture cost. Recent updates are presented regarding chemical absorption-desorption systems, and particularly CO 2 absorption and solubility enhancement studies, absorber operation at elevated pressure, recent developments in absorber configuration, and methods for reducing the heat duty of strippers. Furthermore, recently developed post-combustion hybrid techniques such as the membrane-absorbent hybrid process, the membrane-cryogenic hybrid process, the membrane-adsorption hybrid process, the absorption-electrolysis hybrid process, and the solar thermal electrochemical process (STEP) are discussed. Finally, we suggest areas for improvement and indicate that there are significant future prospects for post-combustion CO 2 capture. C
