Non-linear system identification of solvent-based post-combustion CO2 capture process

Optimal conception of a post-combustion CO2 capture unit with assessment of solvent degradation

The combination of growing energy demand and environmental concerns has made the development of CO2 capture and storage technologies a necessity for the near-future energy mix. Post-combustion CO2 capture is one of the most mature technologies for reducing CO2 emissions in power plants. As a next step for the technology development, large-scale demonstration capture plants have to be implemente...

Detection of Degradation Products of Monoethanolamine- a Post-combustion Co2 Capture Solvent

Using solid phase extraction (SPE) combined with HPLCfluorescence/photodiode array (PDA) detection several low molecular-weight alkylamines (including ethylamine and propylamine) have been detected in the gas-phase, released during the oxidative/thermal degradation of monoethanolamine (MEA), an amine-based postcombustion CO2 capture solvent. In this study, a 30 wt% aqueous MEA solution was degr...

Control of a post-combustion CO2 capture plant during process start-up and load variations

Dynamic and flexible operation of a carbon capture plant is important as thermal power plants must be operated very flexibly to accommodate large shares of intermittent energy sources such as wind and solar energy. To facilitate such operation, dynamic models for simulation, optimization and control system design are crucial. In this paper, we present a dynamic mathematical model for the absorp...

Water Vapor Adsorption on Biomass Based Carbons under Post-Combustion CO2 Capture Conditions: Effect of Post-Treatment

Process Design of Aqueous Ammonia - based Post - combustion CO 2 Capture

In the present work, the aqueous ammonia-based post-combustion CO2 capture (PCC) process is simulated using the rate-based model in Aspen Plus, by which the method of sizing column heights is revealed. The heights of the staged CO2 absorbers and the NH3 absorber are determined as 5 m, 6 m, and 6 m; in addition, the heights of the CO2 and NH3 strippers are 12 m and 6 m, respectively. It is well ...
