“…Higher concentrations of MEA are reported to have lower SRD, especially at high CO 2 capture efficiency (e.g. a test campaign carried out at the Pilot Scale Advanced Capture Technology (PACT) facilities of the UK Carbon Capture and Storage Research Centre (UKCCSRC) [2]). The absorber column diameter is approximated using a method proposed by Chapel et al [8], and a lean loading of 0.16 mol CO 2 /mol MEA is initially assigned.…”

“…Morgan et al (2018) perform a study for a 10 t CO 2 /h pilot plant, and Feron et al (2017) run a pilot plant for 1000 h, and both provide a review of previous studies about MEA pilot plants. In pilot plant experiments, Akram et al (2020) determined that using 40% MEA, the reboiler duty drops by up to 14% compared to the commonly used 30% MEA concentration. Enhanced packings, e.g.…”

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.

“…[1][2][3][4][5] The most widely used CCS media is a 30% aqueous solution of MEA. 6 Briefly, the solvent medium chemically absorbs CO 2 contained in the flue gas, which leads to a CO 2 -depleted gas stream exiting the stack. The solvent is subsequently regenerated and recycled back into the absorber column, while the CO 2 is compressed and captured.…”
