Carbon dioxide was absorbed into water-in-oil (w/o) emulsion composed of aqueous droplets of diethanolamine (DEA) as a dispersed phase and benzene solutions of polybutene (PB) and polyisobutlene (PIB) as a continuous phase in a flat-stirred vessel to investigate the effect of non-Newtonian rheological behavior on the rate of chemical absorption of CO2, where the reaction between CO2 and DEA in the aqueous phase was assumed to be a pseudo-first-order reaction. The liquid-side-mass transfer coefficient, kL, which was obtained from the dimensionless empirical equation containing the properties of pseudoplasticity of the non-Newtonian liquid, was used to estimate the enhancement factor due to chemical reaction. It was expressed that PIB with elastic property made the rate of chemical absorption of CO2 accelerated by comparison of kL in the non-Newtonian liquid with that in the Newtonian liquid. |
