“…The thermodynamic model used in this work is based on the Electrolyte Equation of State (EoS), as originally introduced by Fürst and Renon [6]. This approach has been used to successfully describe CO 2 and/or H 2 S solubilities in aqueous systems containing MDEA, MEA or DEA [7][8][9][10], and in Derks et al [11], it was also proven to be suitable for describing the solubility of carbon dioxide in aqueous piperazine solutions.…”

“…The experimental setup used in this work was essentially the same as the 'continuous setup' used in a previous study [11], and will therefore not be described in detail. However, some modifications were made to make the setup suitable for the determination of pH and conductivity for the experiments in the present work.…”

“…The fourth contribution to the reduced Helmholtz energy stems from the long range ionic forces (LR). All governing equations describing these individual contributions are listed in detail in Derks et al [11], and will therefore not be given here.…”

“…In Derks et al [11], the Electrolyte EoS model was used to successfully describe the CO 2 solubility in aqueous piperazine solutions. From figure 3, it can be concluded that many parameters necessary for the present, quaternary system, model, are also parts of the previously developed model for the ternary system PZ-CO 2 -H 2 O.…”

For technical reasons the number of authors shown on this cover page is limited to 10 maximum. a b s t r a c tIn the present study, new experimental equilibrium data are reported on the solubility of carbon dioxide into aqueous solutions of N-methyldiethanolamine (MDEA) and piperazine (PZ) over a wide range of conditions. These data not only include CO 2 solubilities and their corresponding partial pressures, pH, and conductivities, but also a limited number of liquid speciation data obtained using NMR spectroscopy. The present data, and other data reported in the literature, were correlated with the Electrolyte Equation of State, as originally introduced by Fürst and Renon. The final model was able to describe the thermodynamics of the quaternary CO 2 -PZ-MDEA-H 2 O reasonably well over a wide range of experimental conditions.

“…Development of solvents with high efficiency is regarded as one of the most crucial issues for CO 2 absorption. Many solvents, such as monoethanolamine (MEA), methyldiethanolamine (MDEA), diethanolamine (DEA) and piperazine (PZ), have been applied to capture CO 2 (Bishnoi and Rochelle, 2002;Derks and Dijkstra, 2005;Rinker et al, 2000;Rinker and Ashour, 2000). However, this absorptiondesorption process always requires lots of energy and high operation costs during solvent regeneration.…”

Amine Solutions for Biogas Upgrading: Ideal versus Non‐Ideal Absorption Isotherms

et al. 2013

View full text Add to dashboard Cite

Amine solutions were applied in carbon dioxide removal from a model mixture of biogas, carried out in a loop reactor system. In addition, the effect of CO 2 absorption acceleration in the presence of piperazine was confirmed and quantified, relating the obtained CO 2 loading with the piperazine concentration. Further, the interactions of CO 2 and water in aqueous amine solutions were discussed. The obtained acid gas loadings were accurately described taking into account the effect of the dissolved CO 2 on the equilibrium constant. A logarithmic absorption isotherm that follows from such considerations and a saturation-type isotherm were compared. In describing the experimental data, advantages and disadvantages of both approaches are discussed.
