CO2 post combustion capture with a phase change solvent. Pilot plant campaign

Dynamic model validation of the post-combustion CO2 absorption process

“…It can be seen from Fig. 4 that slightly higher energy performance values were measured in the campaign by Pinto et al (2014) and in this study compared to Tobiesen et al (2007). The difference is not very large and can most likely be explained by the change of packing material and packing height in the stripper.…”

“…1. A detail description of the pilot is given in Pinto et al (2014) and only a short overview is given here.…”

“…Flow rates, temperatures, pressures, gas compositions and liquid density of the rich and lean solvent were logged every minute throughout the experiments and was continued even though liquid sampling was stopped. Based on previous experience, the pilot plant was operated without any further external impact for at least 6 h after every dynamic step change to ensure a steady state starting point for the next dynamic experiment (Pinto et al, 2014). The logged measurements were also checked prior to each experiment to ensure stable values.…”

Useful Mechanisms, Energy Efficiency Benefits, and Challenges of Emerging Innovative Advanced Solvent Based Capture Processes

“…The DEEA + MAPA system operated at high pressure [25] which allowed to produce a pressurised CO 2 stream. More recently the 5 M DEEA/2 M MAPA mixture was investigated in the Gløshaugen plant [29] achieving lower reboiler temperatures and duty (compared to MEA at 30% concentration).…”

“…Challenges also include solvent degradation and volatility. Especially volatility limits solvent selection opportunities and control to avoid solvent losses adds to the plant's OPEX [29].…”
