15 maj 2013 · In this work we applied dynamic gassing-out method for measuring the volumetric mass transfer coefficient kLa in three type gas-liquid reactors (stirred tanks, bubble columns and airlift).
15 mar 2020 · An alternative integral method, that is proposed for first time in this work, appears to offer accurate and reliable estimations of the volumetric mass transfer coefficient. The proposed method, despite its simplicity, has many advantages over the more elaborated methods.
The volumetric mass transfer coefficient (kLa) is a parameter that determines the rate at which a gaseous compound (e.g. O2 or CO2) can transfer between the gas phase and the liquid phase. The ‘kL’ represents the rate of molecular diffusion through the gas-liquid interface and the ‘a’ represents the area of this interface per liquid ...
THE LIQUID PHASE MASS TRANSFER COEFFICIENT kL The liquid phase mass transfer coefficient kL is the rate parameter describing the mass flux from an interface to the bulk (or vice versa) at a given concentration difference AC between the bulk and interface. This coefficient, for gas absorption in a gas/liquid
Online calculator to convert kiloliters to US quarts (kL to US qt) with formulas, examples, and tables. Our conversions provide a quick and easy way to convert between Volume units.
The local mass transfer coefficient can be obtained from molar flux of A, for the case of negligible bulk flow in the z direction (N A + N B =0). Mass transfer coefficient at the phase interphase (z = 0)
mass transfer in porous materials All fluxes and flows (j,J, N, v’) are evaluated per total cross-sectional areas! No surface effects (modified Fick and diffusion-advection equations)
