Absorption removal of carbon dioxide in the presence of inert solid particles (flour powder)

Abstract

Abstract An experimental analysis of the absorption removal of carbon dioxide with the presence of inert solid particles on the surface of the absorbent liquid is presented. A batch absorber with quiescent absorbent liquid has been applied to study the absorption removal of carbon dioxide by water in the isothermal system. The flour powder is introduced as the inert solid particles in the carbon dioxide absorption system. Tests with the flour powder in water are examined. The mass fluxes of carbon dioxide for the cases with and without the flour powder are then compared to elucidate the effects of inert solid particles on isothermal gas absorption. The results indicate a significant difference between these two cases for the concentrations of the flour powder in the absorbent liquid (WF) being in the range of experimental conditions, namely 0.001 to 0.03 g flour in 10 ml liquid. In general, the inert solid particles of the flour powder as the impurities in water with WF in the range of this study tend to ...
