“…The application of the step-change technique to pilot plant operation will significantly improve the consistency and reproducibility of dynamic results. This step-wise technique was previously performed in another PCC pilot plants at Esbjerg Power Station in Denmark (Faber et al, 2010) and RWE Power in Germany (Moser et al, 2011).…”

Flexible operation has the potential to significantly improve the economic viability of post-combustion CO2 capture (PCC). However, the impact of disturbances from flexible operation of the PCC process is unclear.The purpose of this study was to investigate the effects of flexible operation in a PCC pilot plant by implementing step-changes for improved dynamic data reliability. The flexible operation campaign was conducted at the CSIRO PCC pilot plant at AGL Loy Yang using monoethanolamine (MEA) absorbent. The pilot plant was operated under a broad range of transient conditions (changing flue gas flow, liquid absorbent flow and steam pressure) to capture the dynamics of a PCC process during flexible operation. The study demonstrated that the dynamics of flue gas flow rate was faster than absorbent flow rate. The greatest CO2 removal % was achieved at the lowest flue gas flow rate or at the highest absorbent flow rate; however the latter provided improved energy efficiency. The steam pressure parameter could adjust the temperature of all columns simultaneously which can be used to compensate for effects from ambient conditions or heat losses. These results verify the technical feasibility of flexible PCC operation and provide a suitable dataset for dynamic model validation.

“…The recycled solvent is then pumped back to the absorber completing the process cycle. Monoethanolamine (MEA) is the most common choice of a chemical solvent used for these purposes, mainly due to its high reactivity (Alie, 2004) and the existing comprehensive data base of its physical and chemical properties (Kothandaraaman et at., 2009;Moser et al, 2011). Most of the present research of CCS technology is performed in two ways:…”

The paper deals with numerical modelling of carbon dioxide capture by amine solvent from flue gases in post-combustion technology. A complex flow system including a countercurrent two-phase flow in a porous region, chemical reaction and heat transfer is considered to resolve CO 2 absorption. In order to approach the hydrodynamics of the process a two-fluid Eulerian model was applied. At the present stage of model development only the first part of the cycle, i.e. CO 2 absorption was included. A series of parametric simulations has shown that carbon dioxide capture efficiency is mostly influenced by the ratio of liquid (aqueous amine solution) to gas (flue gases) mass fluxes. Good consistency of numerical results with experimental data acquired at a small-scale laboratory CO 2 capture installation (at the Institute for Chemical Processing of Coal, Zabrze, Poland) has proved the reliability of the model.

“…The reaction of MEA with oxygen in laboratory and pilot scale experiments was observed by Moser et al [18] during 500-5000 h of operation. The study suggest that MEA degradation in pilot plants consists more of oxidative than thermal degradation.…”

“…Despite using techniques to prevent amine solvent degradation, it is impossible to stop corrosion in CO 2 capture installations. Oxidative degradation in pilot capture plants is still an issue which can be seen in the results of tests conducted in power plants in Germany [17,18] and Australia [19].…”

Abstract:The correct conduction of the CO 2 capture process in coal-fired power plants with the use of monoethanolamine (MEA) requires constant process parameter monitoring and ensuring a specific flue gas chemical composition. One of the most common problems in these types of installations is the progressive corrosion and degradation of the valuable solvent. Despite the established reduction levels of oxygen and impurities entering into irreversible reactions with the absorber, the flue gas composition may change as a daily and annual function of time. The article presents a detailed analysis of the flue gas components that have the greatest influence on carbon dioxide capture installation technical safety, i.e., SO x , NO x , O 2 , and fly ash. The analysis was based on the results of experiments conducted at the Jaworzno III Tauron Wytwarzanie SA Polish coal power plant. The results show a significant influence of the flue gas desulfurization (FGD) process on MEA oxidative degradation. The amount of oxygen in flue gas during biomass and coal blend co-firing was nearly twice as low compared to pure coal combustion. Differences were also observed in the amounts of gas impurities with relation to the time of year and time of day of power plant operation.
