“…The practical issues associated with the use of amine solvents include the thermal and oxidative degradation caused during the cyclic absorption–desorption process. , Corrosion of process equipment and flow lines has also been reported when amine solvents are used. Solvent loss due to volatilization, high-energy consumption during regeneration, and a toxic nature are the additional negative aspects of these usual solvents. − These demerits of amine-based solvents restrict their use for CO 2 removal processes.…”

The physicochemical properties such as density, viscosity, and refractive index of aqueous solutions of sodium l-prolinate (SP) as a solvent for CO2 capture was measured. These properties were measured at different temperatures from (298.15 to 343.15) K. The mass fractions of SP were 0.05, 0.10, 0.20, 0.30, and 0.40. The coefficient of thermal expansion was calculated from the experimental density values in the same temperature range. The analysis of experimental results shows that the densities, viscosities, and refractive indices of the aqueous solutions of SP increase with an increase in the mass fraction in the solution, and decrease with increasing temperature. The thermal expansion coefficient slightly increases with increasing temperature and concentration. The experimental data of density, viscosity, and refractive index were correlated by the least-squares method as a function of temperature. The predicted data were estimated from correlation coefficients for all measured properties and reported with standard deviations.

“…5 In continuation of these endeavors; various technologies have been developed to mitigate CO 2 emission. [12][13][14][15] An aqueous solution of potassium carbonate has also been used as a CO 2 capture agent since it has a lower rate of degradation and lower cost as compared to amines. These technological options are in operation to capture CO 2 but efforts are being undertaken to improve these techniques.…”

The physical properties, such as densities, viscosities, and refractive indices, of aqueous solutions of potassium carbonate (PC) blended with glycine (Gly) as solvent blends for CO 2 capture were measured. The properties were measured at ten different temperatures from (298.15 to 343.15) K. The mass fractions (w 1 +w 2 ) of the (PC+Gly) blends were 0.05+0.01, 0.10+0.02, 0.15+0.03, 0.20+0.04, 0.25+0.05, 0.30+0.06, 0.35+0.07 and 0.40+0.08 %, respectively. An analysis of the experimental results showed that the densities, viscosities, and refractive indices of the aqueous (PC+Gly) blends increase with increasing concentration of potassium carbonate and glycine, and decrease with increasing the temperature. The experimental data of density, viscosity and refractive index were correlated by a least-squares method as a function of temperature. The predicted data were estimated from coefficients of correlation equations for all the measured properties, and reported with standard deviation (SD). The experimental data were consistent with the predicted data.

“…After the long time use of amine-based solvents, it is identified that there are various potential drawbacks of the amine-based solvents used for the absorption of CO 2 . The identified potential drawbacks include inadequate lifetime due to amine oxidation degradation and as a result corrosion occurrence in pipelines and equipment which causes unplanned downtime, reduced equipment life, production losses, and management expenses to restore a corroded system. ,, The energy cost is too high during desorption in combination with a high loss of liquid due to the evaporation of the solvent because of solvent’s high volatility in the stripper. − In addition, flooding and entrainment of the absorption liquid limit the process, and the liquid gas stream cannot be controlled independently . Chemical solvents based on amino acids have been proposed in place of the amine-based solvents due to the various benefits.…”

Physical Properties of Aqueous Blends of Sodium Glycinate (SG) and Piperazine (PZ) as a Solvent for CO₂ Capture

et al. 2013

The physical properties including the density, viscosity, and refractive index of aqueous blends of sodium glycinate (SG) and piperazine (PZ) as a solvent for CO2 absorption were measured under the wide temperature range (298.15 to 343.15) K. Different concentrations (mole fraction) of sodium glycinate and piperazine (SG + PZ) blends were (0.0348/0.0089, 0.0263/0.0177, 0.0177/0.0263, and 0.0089/0.0348), respectively. From the observations, it was found that the densities of the aqueous blends decrease when the piperazine concentration in the blend increases. It was noticed that the viscosity of the blend decreases initially by increasing the concentration of piperazine from 0.0089 to 0.0177 mole fraction; however, on further increasing the piperazine and decreasing the sodium glycinate concentration in the blend, the viscosity tends to increase. The refractive indices of the aqueous blend of sodium glycinate and piperazine decrease with increasing the concentration of piperazine in the blend. The density, viscosity, and refractive index of an aqueous blend of (SG + PZ) decreases with increasing temperature. The measured values of density, viscosity, and refractive index were correlated as a function of temperature by using standard equations of the least-squares method. All of the correlation parameters were reported together with the standard deviation.
