Oct 15, · Oxygen mass transfer. Oxygen mass transfer studies in the medium were carried out using a square bubble column contactor built in Perspex (polymethylmethacrylate—PMMA) with a working volume of L and geometrical characteristics of 4 cm inside side-length and height of 65 springhigheredcio.com by: Request PDF | Oxygen Mass Transfer in Bubble Column Bioreactor | In the present study volumetric oxygen mass transfer coefficient kLa has been determined for biodegradation of phenol in a bubble. The model is developed to include the case of non-Newtonian fermentation media which are involved in many industrially bioprocesses. on oxygen transfer in a bubble column were studied. Oxygen mass transfer to emulsions in a bubble column contactor Article in Chemical Engineering Journal () · October with Reads How we measure 'reads'.
Mass transfer is then described by penetra- tion theory9. This describes non- stationary mass transfer into an infinite medium which initially has an oxygen concentration equal to the bulk concen- tration. The liquid is exposed to the gas bubble for a very short time, equal to that of the displacement of the gas bubble over its springhigheredcio.com by: Oxygen mass transfer to emulsions in a bubble column contactor Diego Gómez-Díazb,∗, Nelma Gomes a, José A.

Oxygen transfer mechanisms in the gluconic acid fermentation byPseudomonas ovalis. Biotechnology and Bioengineering , 6 (3), DOI: /bit N. Blakebrough, G. Hamer. Resistance to oxygen transfer in fermentation springhigheredcio.com by: Nov 10, · The volumetric gas-liquid mass transfer coefficient, k L α, for oxygen was studied by using the dynamic method in slurry bubble column reactors with high temperature and high pressure. The effects of temperature, pressure, superficial gas velocity and solids concentration on the mass transfer coefficient are systemically discussed.
Oxygen mass transfer in bioreactors involves many mass-transfer resistances. on mass transfer of oxygen in a bubble column containing 1 wt% aqueous CMC was studied. The efficiency of.
