Rate based modeling and validation of a carbon-dioxide pilot plant absorbtion column operating on monoethanolamine

A rate based model of a packed column for CO2 absorption using aqueous monoethanolamine solution

“…Currently, research effort is also being devoted to the overall reaction mechanisms involved in the CO 2 absorption into amine and its effects on the absorption efficiency (Sexton and Rochelle, 2011;Bedell, 2011;Qin et al, 2010;Mindrup and Schneider, 2010;Lepaumier et al, 2009a,b;Lepaumier et al, 2010). In addition, detailed mathematical models based on both film and penetration theories are being developed (Simon et al, 2011;Faramarzi et al, 2010;Edali et al, 2009;Zhang et al, 2009;Lawal et al, 2009;van Loo et al, 2007). This paper presents a comprehensive and simplified rate based mathematical model for a packed column for the reactive absorption of CO 2 into aqueous amine solution.…”

Experimental studies of regeneration heat duty for CO2 desorption from diethylenetriamine (DETA) solution in a stripper column packed with Dixon ring random packing

“…The MEA concentration at 5.0 kmol/m 3 as well as lean and rich CO 2 loadings of 0.25 and 0.50 mol/mol, respectively, has been considered to be the optimized condition for MEA-based post-combustion CO 2 capture process, and has been used as the base case for comparison with other solvents in pilot plant tests and simulation studies [34][35][36][37]. Therefore, Q reg of MEA at these conditions can reasonably be considered as a benchmark for comparison in this work.…”

Flexible operation of CSIRO's post-combustion CO2 capture pilot plant at the AGL Loy Yang power station

“…Conventionally, most pilot plant studies will measure liquid phase CO2 loading, density and MEA concentration using off-line laboratory analysis (Dugas, 2006;Artanto et al, 2009;Seibert et al, 2010;Simon et al, 2011;Artanto et al, 2012). However, such techniques are unable to illustrate dynamic changes in liquid absorbent composition van Eckeveld et al, 2014).…”
