New experimental CO 2 solubility data at equilibrium in an aqueous blend of 2-(diethylamino)ethanol (DEEA) and (2-aminoethyl) ethanolamine (AEEA) have been illustrated for the concentration of CO 2 in the inlet gas stream ranging from 10.132 to 20.265 kPa and aqueous amine blend temperature ranging from 303.14 to 333.14 K. Total concentrations of aqueous blend were taken in the range of 1.0−3.0 kmol/m 3 and mole fraction of AEEA in total amine blend in the range of 0.02−0.20. Experiments were carried out in a semibatch operated laboratory scale gas−liquid bubbling absorber, and analysis of liquid phase CO 2 as a saturated liquid was done by titration method. The equilibrium CO 2 solubility in DEEA + AEEA blend was found to be a maximum at the value of 0.843 mol CO 2 /mol amine with AEEA mole fraction in total amine of 0.2 at 1 kmol/m 3 total concentration of amine mixture and 303.14 K. New solubility data of CO 2 in the present work was compared with existing literature data. An empirical correlation was developed from experimental CO 2 solubility data as a function operating variables in the studied range.

“…Authors studied the absorption of CO 2 at different TSP concentrations (1.0-2.0 kmol/m 3 ), temperatures (303.14-333.14 K), and inlet CO 2 partial pressures . It was reported [23] that CO 2 solubility increases with increasing TSP concentration as well as temperature. It was also reported that the CO 2 solubility increases with the increasing mole fraction of TSP at a fixed temperature and partial pressure of CO 2 .…”

Carbon Dioxide Capture from Flue Gas Using Tri-Sodium Phosphate as an Effective Sorbent

Fossil fuels are dominant as an energy source, typically producing carbon dioxide (CO2) and enhancing global climate change. The present work reports the application of low-cost tri-sodium phosphate (TSP) to capture CO2 from model flue gas (CO2 + N2) mixture, in a batch mode and fixed-bed setup. It is observed that TSP has a high CO2 capture capacity as well as high CO2 selectivity. At ambient temperature, TSP shows a maximum CO2 capture capacity of 198 mg CO2/g of TSP. Furthermore, the CO2 capture efficiency of TSP over a flue gas mixture was found to be more than 90%. Fresh and spent materials were characterized using powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), and Fourier transformed infrared spectroscopy (FTIR). Preliminary experiments were also conducted to evaluate the performance of regenerated TSP. The spent TSP was regenerated using sodium hydroxide (NaOH) and its recyclability was tested for three consecutive cycles. A conceptual prototype for post-combustion CO2 capture based on TSP material has also been discussed.

“…After a regular interval of 30 min, the outlet gas stream was analyzed for CO 2 concentration in the gas, and this procedure was repeated until the equilibrium was reached by confirming the same concentration of CO 2 in both inlet and outlet gas stream. The CO 2 capture in the liquid sample at equilibrium was measured by the most reliable and promising standard titration method with 0.6 mol % of HCl solution using phenolphthalein as indicator followed by methyl orange indicator until to reach the end point . Titration of two more aliquot samples was performed to check the reproducibility of data and it was within 0.5 %.…”

Most of the researchers have shown growing interest in solubility related phenomena in the field of CO 2 capture. In the present work, the new experimental CO 2 capacity data at equilibrium in aqueous absorbent containing trisodium phosphate (TSP) and piperazine (PZ) have been presented at inlet partial pressures of CO 2 from (9.96 to 20.28) kPa, temperature ranging from (303 to 353) K, and total blend concentrations from (1.0 to 3.0) mol•kg −1 using a bubbling absorber. The results were compared with the literature to show the effectiveness of this novel blend absorbent system.
