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 ...
31 lip 2019 · The document discusses measurement of the volumetric mass transfer coefficient (KLa), which indicates the rate of oxygen transfer in a bioreactor. It describes various methods to determine KLa values, including chemical and physical techniques like the sodium sulphite oxidation method.
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).
The predicted overall mass transfer coefficient reported came directly from the particles_bubbles.txt output file associated with each run. The predictions agree with experiment in both magnitude and trend: higher impeller speed and higher gas flow rate lead to higher mass transfer rates.
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)
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)
