Solubility of SO2 in aqueous blend of sodium citrate and sodium hydroxide

SO2 removal from simulated flue gas using various aqueous solutions: Absorption equilibria and operational data in a packed column

“…show that the negative effects of temperature on SO 2 solubility and evaporation are slightly higher than its positive effect on diffusivity [2,19]. This is in consistence with the results obtained in most cases of gas dissolution into a liquid [41].…”

“…So, in order to introduce sodium lysinate solution as an appropriate alternative for desulfurization process, various important operating factors affecting the removal efficiency including SO 2 inlet concentration, process temperature and L/G were discussed. These experiments reveal that high temperature is not favorable for SO2 …”

“…The majority of industrial SO 2 emissions, which come from the burning of fossil fuels, are mainly led to air pollution, acid rain and urban smog [2].…”

“…Several difficulties of above mentioned absorbents such as low biodegradation, no environmental friendly, high vapor pressure and relatively low absorption capacity in low solvent concentrations, led to new type of absorbents with features close to the amines solution called amino acid salts were tested in SO 2 removal. In previous researches on CO 2 removal, amino acid salt solutions showed attractive performance for CO 2 absorption because of their low environmental impact, with characteristics such as low volatility due to its ionic structure, low ecotoxicity, and high biodegradability [18]. Recently SO 2 solubility of six water-soluble amino acids aqueous solutions was studied to remove SO 2 from SO 2 -N 2 system [19].…”

Solubility and Spectral Studies for SO2 in a Binary System of Triethylene Glycol + Dimethyl Sulfoxide at T = (298.15, 303.15, and 308.15) K and p = 123.15 kPa

“…Combustion of coal and diesel fuels and an inordinate increase of SO 2 emission has become a world focus, especially in industrial countries . The majority of industrial SO 2 emission leads to air pollution, acid rain, and urban smog; thus, it is necessary to capture SO 2 from gaseous streams before it is emitted. The organic solvent absorption method was considered as a reliable and relatively competitive method for the mitigation of SO 2 emission from fossil fuel power plants because of high removal efficiency and low cost. , Therefore, it is very necessary to choose new type of organic solvent that is efficient, economic, and renewable.…”
