Influence of liquid viscosity and surface tension on the gas–liquid mass transfer coefficient for solid foam packings in co-current two-phase flow

CO2 capture by aqueous solutions of glucosamine in a bubble column reactor

“…7). The effect of viscosity upon the mass transfer in gas-liquid systems has been deeply studied observing a negative effect in all the cases, producing a clear decrease in the mass transfer coefficient value [21,22], and (ii) the presence of electrolytes in the liquid phase, due to the hydrochloride acid (accompanying to glucosamine molecule) and the addition of sodium hydroxide, has a negative effect upon the mass transfer coefficient, as these substances produce an increase in liquid phase viscosity (see Fig. 7).…”

Gas–Liquid Mass Transfer Characteristics in a Gas–Liquid–Solid Bubble Column under Elevated Pressure and Temperature

“…Since the mass transfer coefficient is inversely proportional to the square root of the contact time according to the Higbie's penetration theory [25], k L will decrease. Moreover, the decrease of liquid viscosity will increase the mass transfer coefficient, because k L is inversely proportional to the liquid viscosity [3,26,27]. So, the overall effect of pressure leads to the slight variation of k L values with the increase of pressure.…”

Qualitative and quantitative insights into multiphase flow in ceramic sponges using X-ray computed tomography

“…Some publications about hydrodynamics in sponges also exist. Schouten and colleagues (Stemmet et al, 2005(Stemmet et al, , 2007(Stemmet et al, , 2008Wenmakers et al, 2010) investigated the liquid hold-up, the mass transfer coefficient, the flooding point and the axial liquid dispersion coefficient of metal sponges. The hold-up was measured by replacement of fluid by gas.…”
