“…Corrosion in 30 wt% MEA-based pilot plants, namely Dong Energy's Ebsjerg and TNO's Maasvlakte have recently been evaluated using weight loss technique with corrosion coupons-plant inspection and on-line monitoring using electrochemical probes. Based on this test campaign (De Vroey et al, 2013), 6 corrosion coupons placed in different locations throughout the Ebsjerg plant and one electrochemical probe installed at the stripper liquid outlet of the Maasvlakte have produced consistent corrosion rate measurements that can be correlated well between the 2 plants. Based on the results, the corrosion rates on stainless and carbon steel measured from both plants would not be expected to affect the plants' structural integrity.…”

Greenhouse Gas Control (2015), http://dx.Keywords: Recent development of PCC process Design and modeling Solvent development Post Build Operations Solvent chemistry Solvent management Mass transfer with reaction a b s t r a c tCurrently, post-combustion carbon capture (PCC) is the only industrial CO 2 capture technology that is already demonstrated at full commercial scale in the TMC Mongstad in Norway (300,000 tonnes per year CO 2 captured) and BD3 SaskPower in Canada (1 million tonnes per year CO 2 captured). This paper presents a comprehensive review of the most recent information available on all aspects of the PCC processes. It provides designers and operators of amine solvent-based CO 2 capture plants with an in-depth understanding of the most up-to-date fundamental chemistry and physics of the CO 2 absorption technologies using amine-based reactive solvents. Topics covered include chemical analysis, reaction kinetics, CO 2 solubility, and innovative configurations of absorption and stripping columns as well as information on technology applications. The paper also covers in detail the post build operational issues of corrosion prevention and control, solvent management, solvent stability, solvent recycling and reclaiming, intelligent monitoring and plant control including process automation. In addition, the review discusses the most up-to-date insights related to the theoretical basis of plant operation in terms of thermodynamics, transport phenomena, chemical reaction kinetics/engineering, interfacial phenomena, and materials. The insights will assist engineers, scientists, and decision makers working in academia, industry and government, to gain a better appreciation of the post combustion carbon capture technology.

“…According to De Vroey et al (2013), additional investigation on corrosion using coupons, on-line monitoring using electrochemical probe, and pilot plant inspection were also performed with MEA solvent separately in both the Dong Energy's pilot plant at Esbjerg (Denmark), and TNO's Maasvlakte pilot plant (The Netherlands). De Vroey et al (2013) reported that the weight loss measurement of coupons (placed in strategic locations throughout the process) correlated well with on-line measurement using the electrochemical techniques. Corrosion resistance in most zones in the pilot plants using carbon and stainless steels in the tests was generally good.…”

“…Many of the degradation products of amines are known to be corrosive. ,, Several corrosion studies have been performed at laboratory and pilot plant scale with different solvents and materials. The laboratory scale studies used electrochemical measurements at different temperatures, CO 2 loadings, oxygen content, gas phase impurities such as SO 2 and NO 2 . − Corrosion has been evaluated at several pilot plants using MEA and other solvents. ,− The process equipment that are typically vulnerable to corrosion include columns (absorber and stripper), amine heat exchanger, regenerator, and reclaimer. Typically, coupons are installed at different locations in the pilot plant and their weight loss is translated into corrosion rate as per standard norms, such as ISO 8407 and ASTM G1-03.…”

Corrosion in amine treating plants is known to cause integrity failures, plant shutdown, costly repairs, and so forth. The use of an amine treatment system for postcombustion CO 2 capture brings additional challenges in terms of the flue gas quality, flue gas composition, operating conditions, scale of operation, and so forth. These differences are expected to have a significant impact on the overall well-being of the plant and the maintenance strategy over its lifetime. The degradation of solvent, by oxidative and thermal degradation pathways, leads to the formation of various degradation products which are known to be corrosive. The oxidative degradation of amine leads to the formation of ammonia which can be emitted to the atmosphere in the treated flue gas stream. This study aims at verifying the interrelation between (1) solvent degradation, (2) corrosion, and (3) NH 3 emissions, based on two test campaigns of over 1500 operating hours, in a CO 2 capture pilot plant. An online tool for real-time corrosion monitoring, SmartCET, is presented and compared with offline corrosion coupon. The different process and operating conditions such as the change in the flue gas composition, start-up and shutdown, and solvent replacement were correlated with the variations in the corrosion parameters (general corrosion rate, pitting factor, and corrosion mechanism indicator (CMI)), for both campaigns. The three parameters showed only a small increase for most part of both the campaigns (>75 days), and followed a similar trend. However, during both the campaigns, a rapid increase of all the three parameters was observed. In one of the campaigns, the three parameters increased by about 2 orders of magnitude in a time period of only about 20 days, which points toward an autocatalytic out of control solvent chemistry. The common characteristic before the onset of autocatalytic solvent chemistry, is the re-start-up of the pilot plant after an extended period of shutdown. On the basis of these tests, the use of an online corrosion monitoring tool will enable long-term steady state operation of a full scale postcombustion CO 2 capture plant.
