Journal ArticleDOI
Interfacial area and boundary of hydrodynamic flow region in packed column with cocurrent downward flow.
TL;DR: In this paper, an empirical equation of liquid holdup and interfacial areas was presented in terms of Reynolds numbers of gas Reg( =dsGg/μg) and liquid Rel, surface shape factor of packing φ, void fraction e and ratio of packing to column diameter dp/T, where the ratio is smaller than 0.13.
Journal ArticleDOI
Liquid-phase volumetric and mass-transfer coefficient, and boundary of hydrodynamic flow region in packed column with cocurrent downward flow.
TL;DR: In this paper, the authors measured liquid-phase volumetric coefficients and Peclet numbers in liquid mixing with cocurrent downwardflow in packed columns and obtained the boundaries for the respective flow regions, obtained by combining two of these equations.
Journal ArticleDOI
Gas-liquid mass transfer and hydrody-namic flow region in packed columns with cocurrent upward flow
TL;DR: In this article, the authors measured liquid holdup and interfacial area in columns packed with 1/2 and 1 in. ceramic spheres for upward cocurrent-flow mode, where the ratio of packing to column diameter, dp/dT, is 0.085, 0.128 and 0.169.
Journal ArticleDOI
Boundary of hydrodynamic flow region and gas-phase mass-transfer coefficient in packed column with cocurrent downward flow.
Journal ArticleDOI
Mass transfer on multi-strings of touching spheres.
TL;DR: In this paper, the authors measured the interfacial areas and liquid phase volumetric mass transfer coefficients from chemical absorption of oxygen into sulfite solution and from physical absorption of carbon dioxide into water, respectively, in the cases of one, two, three and seven strings of touching spheres, and in irrigated columns packed with spheres, Raschig rings and Berl saddles.
