Amine post-combustion carbon capture technology is based on washing the flue gas with a solvent that captures CO 2 . Thus, a small fraction of this solvent can be released together with the cleaned flue gas. This release may cause environmental concerns, both directly and indirectly through subsequent solvent degradation into other substances in the atmosphere. The paper presents the ammonia emission from CO 2 capture pilot plant (1 tonne CO 2 per day) using 40 wt% aminoethylethanolamine solvent, along with the efficiency of the water wash unit. In addition, the temperature effect of lean amine entering the absorber on ammonia emission was studied. Furthermore, the concentrations of other compounds such as SO 2 , SO 3 , NO 2 , CS 2 and formaldehyde were monitored. The literature review on the NH 3 emission from a pilot plant using aminoethylethanolamine solvent has not been published. The results show that the main source of ammonia emission is the absorber and that emission (in the range 27-50 ppm) corresponds to typical NH 3 release from CO 2 capture pilot plant using an amine solvent. The emission of amines and amine degradation products is a complex phenomenon which is difficult to predict in novel solvents, and for this reason the significance of new solvents testing in a pilot scale has been highlighted.

“…absorption of CO 2 in the solvent and regeneration of rich solvent (i.e. loaded with CO 2 ) under the increased temperature and/or reduced pressure [19,20]. Undesirable compounds are formed in the MEA solution as a result of both CO 2 absorption and desorption, as a result of amine degradation.…”

In the ethanolamine (MEA) solution, during the absorption and desorption of CO2 undesired compounds are produced as a result of degradation of an amine. Degradation not only reduces the absorption capacity of the solution but also leads to many operational problems. Furthermore, measuring of the degradation products is of great importance in terms of environmental issues. For the determination of MEA degradation products, mainly chromatographic techniques are used, sometimes coupled with other instrumental methods, e.g. GC-MS. As a part of this work, research was conducted to identify MEA thermal and oxidative degradation products and to develop a method for quantitative analysis of the main thermal degradation products such as OZD, HEIA and HEEDA and oxidative degradation products: HEA and HEI. Samples drawn from a test bench for CO2 capture from synthetic flue gas with an increased content of carbon dioxide were tested. As a research result, a method for the quantitative determination of the main degradation products was developed, the concentrations of degradation products and the rate of their formation were determined, which allows to qualify the solution shelf life.

The carbon dioxide concentration in the atmosphere has reached extremely high levels, generating environmental concerns. Unfortunately, despite the climate change, CO2 is not included nowadays as a key environmental issue in Best Available Technique (BAT) reference documents (BREF). Industrially, the widespread industrial technology to capture CO2 is the chemical absorption using aqueous monoethanolamine (MEA) at 30%wt, which is the basis of comparison for novel alternative techniques in the literature and seems a suitable candidate to be proposed as Best Available Technique. Nevertheless, there is an intense research to find alternative solvents that decrease the energy consumption for carbon capture and many solvents are claimed in the literature to outperform MEA. A novel empirical surrogate model and exergy balances are used to confirm that MEA is still the best candidate to be proposed as Best Available Technique. The surrogate model proposed in this study properly regresses the CO2 gas liquid equilibrium data. The regressed parameters of the model are tabulated in this study for many aqueous alkanolamines and their mixtures, being the basis for computationally inexpensive chemical absorption column design. The surrogate model parameter considering the temperature is related with the chemical absorption energy and the consumed energy for solvent recovery. The obtained results show that none of the considered alkanolamine outperforms MEA in all the considered aspects, i.e. energy and solvent flowrate. MEA minimum flowrate is 15.62 mol solvent/mol gas and its heat of absorption regression parameter is − 27,745 J/mol. The proposed mathematical method is useful as a fast assessment for other novel alternatives that will be proposed in the future, providing energetically more efficient and cleaner technologies for CO2 capture.
