Absorption of sulfur dioxide in N-formylmorpholine: investigations of the kinetics of the liquid phase reaction

Simultaneous absorption of carbon dioxide, sulfur dioxide, and nitrogen dioxide into aqueous 1, 8-diamino-p-menthane

“…3, 4, and 5, the molar flux of each species is mainly dependent on its solubility, as shown in Eq. (8), (9), and (12).…”

“…The absorption of SO 2 [6,7] into aqueous slurries of sodium, calcium and magnesium compounds, serving as the absorbent, and alkaline solutions, has been studied for decades. The medium used in the alkaline solutions was typically alkaline salts [8], inorganic acids [9], organic acids [10], and amines for reversible reaction [11,12]. Danckwerts [13] showed that SO 2 in an alkaline solution was absorbed by an instantaneous reaction.…”

Simultaneous absorption of carbon dioxide, sulfur dioxide and nitrogen dioxide into aqueous 2-amino-2-methy-1-propanol

“…The mass transfer coefficient (k jw ) was calculated by the following equation with the initial volumetric absorption rates of CO 2 , and V/t 1 , obtained from the cumulative volume of gas which flowed through the soap film meter. (13) where P T is the atmospheric pressure, P W o the vapor pressure of water, S the surface area of liquid phase, C ji the solubility of j gas in water, and V(t 1 ) the cumulative volume of gas during the absorption time, t 1 .…”

“…The medium used in the alkaline solutions was typically alkaline salts [9], inorganic acids [10], organic acids [11], and amines for reversible reaction [12,13]. Danckwerts [14] showed that SO 2 absorption in an alkaline solution was an instantaneous reaction and Hikita et al [15] proposed a penetration theory model based on the two-reaction model using approximate analytical solutions to investigate the kinetics of SO 2 with reactants in the liquid phase.…”

Absorption of dilute sulfur dioxide in aqueous poly-ethylene glycol 400 solutions at T=308.15K and p=122.60kPa

“…There is considerable interest in the solubility of SO 2 because of its importance in industrial applications and in pollution control [1][2][3][4][5]. Among the many procedures employed to desulfurize exhaust gases, organic solvents used as absorbents have been identified as an option among the regenerative processes [6][7][8][9][10] because regeneration can be done by pressure reduction, by temperature increase, and by use of a carrier gas. Therefore, our research group has paid great attention to the (alcohol + water) system for SO 2 removal for several years [11][12][13][14].…”
