Absorption of Carbon Dioxide into Aqueous Colloidal Silica Solution

Absorption of carbon dioxide into aqueous PAA solution containing diethanolamine

“…Park et al (2003Park et al ( , 2004 presented the effect of elasticity of PIB in the benzene solution and in the w/o (water in oil) emulsion, which is composed of an aqueous alkaline solution as the dispersed phase and a benzene solution as the continuous phase, on the absorption rate of CO 2 . Park et al also measured the absorption rate of CO 2 in aqueous PAA solution with NaOH (Park et al, 2005a) and in aqueous PEO solution with monoethanolamine (Park et al, 2005b), PEO with treiethanolamine (Park et al, 2006a) and in aqueous colloidal silica (Park et al, 2006b). They showed that the viscoelastic polymers, such as PIB, PAA, PEO and colloidal silica influenced the absorption rate of CO 2 .…”

“…The experimental procedure was the same as that as reported in detail previously (Park et al, 2006b). The solubility (C Ai ) of CO 2 in aqueous DEA (Blanc and Demarais, 1984) solution was estimated as follows:…”

“…A straight impeller (3.4 cm length, 1.7 cm width and 0.5 cm thickness) was used as the liquid phase agitator; it was located at the middle position of the liquid phase of 0.833 dm 3 . The absorption rate of CO 2 was measured in the aqueous PAA solution along the procedure similar to those reported elsewhere (Park et al, 2006b) at 0.101 MPa and 25 8C, in which PAA concentration of 0-10 wt% and concentration of DEA of 0-2 kmol/m 3 were varied at the impeller of agitation speed of 50 rpm and size of 0.034 m.…”

Absorption of Carbon Dioxide into Aqueous Xanthan Gum Solution Containing Monoethanolamine

“…Solubility (C Ai ) of CO 2 in the aqueous XG solutions was obtained using the pressure measuring method, which measured the pressure difference of CO 2 before and after equilibrium in the gas and liquid phases, similar to the procedure reported elsewhere (22) at 258C and 0.101 MPa. The detailed experimental procedure was reported in our earlier work (8).…”

“…Park and coworkers (4,5) presented the effect of elasticity of PIB in the benzene solution and in the w/o (water in oil) emulsion, which is composed of an aqueous alkaline solution as the dispersed phase and a benzene solution as the continuous phase, on the absorption rate of CO 2 . Park and coworkers (6)(7)(8) also measured the absorption rate of CO 2 in aqueous PAA solution with NaOH, PEO solution with triethanolamine, and nanometer sized silica colloid solution with diethanolamine, respectively. They showed that the viscoelastic materials, such as PIB, PAA, PEO, and nanometer sized silica influenced the absorption rate of CO 2 .…”
