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
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 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 ...
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.
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)
25 mar 2022 · This chapter will briefly review fundamentals of mass transfer in gas-liquid systems because many of the separation processes in this handbook involve the movement of species between gas and liquid phases.
transfer coefficient kL, with which the amount of gas dissolved after the liquid falls the distance L can be computed. The problem is solved by simultaneous solution of the equation of continuity
