Overall process analysis and optimisation for CO2 capture from coal fired power plants based on phase change solvents forming two liquid phases by Ulrich Liebenthal( )

2 editions published in 2013 in English and held by 3 WorldCat member libraries worldwide

In this work the potential of a novel post-combustion CO2 capture process is analysed with respect to the integrated overall process. As solvent a blend of two amines (DEEA/MAPA) which forms two liquid phases under CO2 loading is used. The two phases have distinct physical characteristics. Only the heavy phase, rich in CO2 loading, is led to the desorber. The novel solvent combination promises very low energy consumption compared to a 30 wt.-% MEA solution. The efficiency penalty, taking into account the integrated overall process, is very low too. Furthermore, different integration configurations in the overall process are investigated to show the effect in greenfield and retrofit power plant cases. © 2013 The Author
Experimental Determination of Mass-transfer Coefficients and Area of Dumped Packing Using Alkanolamine Solvents( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

Abstract: The absorption process is strongly influenced by the effective contact area. In absorber columns, this is related to the type of the internals used in the columns. Therefore, a good representation of the effective mass-transfer area and mass-transfer coefficients (kL or kg) is also essential for accurately represent and design a process. For CO2 capture process packed columns are usually preferred. The mass transfer area and coefficients for several packing (both structured and random) are correlated elsewhere. In this work mass transfer experiments using concentrated MEA solution in the Procede acid gas treating pilot plant are performed. However, due to the fast reaction between MEA and CO2, both the gas side and liquid side mass transfer resistances are relevant and the mass transfer area cannot be determined experimentally. Nevertheless, the volumetric mass transfer coefficient is calculated and it showed to be relatively constant for all the runs. The results from the pilot plant are compared to simulated results using Procede Process Simulator (PPS). The mass transfer area and mass transfer coefficients were calculated through the default correlations implemented in PPS. Very good agreement is achieved between the experimental and simulated results
Viscosity measurements and modeling of loaded and unloaded aqueous solutions of MDEA, DMEA, DEEA and MAPA( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

Highlights: Viscosity of unloaded MDEA, DMEA, DEEA and MAPA aqueous solution were measured. Viscosity of CO2 loaded MDEA, DEEA and MAPA aqueous solution were measured. The NRTL-DVIS model was used to correlate the data both loaded and unloaded. The model predicts the experimental data with reasonable accuracy. Abstract: Viscosities of aqueous solutions of 4 amines aimed at CO2 capture by absorption were measured in the temperature range 20-80 ° C and for the whole range of compositions. In addition, measurements for loaded solutions up to 1 mol CO2 /mole amine for three of the amines systems were also performed. The data were, when possible, compared to literature data and good agreement was found. Both the unloaded and loaded data were modeled using the NRTL-DVIS correlation. The model was able, in both cases, to accurately represent the experimental data except for the 17.9 wt.% MAPA loaded system. The average deviations, calculated as AARD between experimental and predicted values, were for all other cases within 5-6%
