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 ...
local energy dissipation rate. A correct representation of all four individual mechanisms, along with a correct prediction of the oxygen transfer rate, indicate a mechanistically robust bioreactor model.
15 mar 2020 · The liquid hold-up is constant and combining Eqs. (1) and (2) the following equation is obtained: (3) d C O 2 d t = k L a (C O2,s − C O2) where a= Ai / VL is the interfacial area for mass transfer per unit volume of the liquid into the vessel.
24 paź 2021 · For a successful aerobic cultivation, a good oxygen transfer is vital. The determination of the volumetric oxygen transfer coefficient (k<sub>L</sub>a) and the OTR helps you to optimize the bioprocess in bioreactors and ensure a successful scale-up process.
Another important aspect of kLa can be described using the following equation: where. – the saturated dissolved oxygen concen-tration; – the current concentration of dissolved oxygen in the media. kLa and the diference . L) and maximal pos-sible (or sometimes termed equilibrium C*)
