Gas to liquid mass transfer in rheologically complex fluids

Study on Mass Transfer Enhancement in a Gas-Liquid System Using Nanomaterials

The main objective of this paper is to examine the effect of nanomaterials on mass transfer coefficient in bubble type absorption of carbon dioxide by experiment. The absorption process is carried out in a bubble column and in room temperature. Mass transfer coefficient, saturated concentration of CO2, and gas holdup are determined in this system. The kinds of nanomaterials, the concentrations ...

Mass Transfer in a Closed Stirred Gas / Liquid Contactor Part 1 : The Mass Transfer Rate

Liquid phase mass transfer rates kLS for the absorption of oxygen in tap water and in aqueous ionic solutions have been determined in two closed stirred tank contactors for a power input between 3 and 70 W/kg and (impeller diameter)f(tank diameter) ratios DifT of 0.3, 0.35 and 0.4. The contactors had diameters of 0. I9 and 0.6 m. The dispersed phase fraction was 1% by volume in all experiments....

Gas–liquid nucleation in associating fluids

The density functional approach to nucleation is extended to the study of the condensation of associating fluids. We use Wertheim theory for associating liquids in a system of spherical interacting molecules with single association sites. Our calculations show that classical nucleation theory largely underestimates the height of the nucleation barrier in this kind of system, but most of that er...
