Estimation of the volumetric oxygen tranfer coefficient (KLa) from the gas balance and using a neural network technique
(Brazilian Society of Chemical Engineering, 1999-06-01)
This paper reports on the use of the gas balance and dynamic methods to obtain an estimate of the volumetric oxygen transfer coefficient (kLa) in a conventional reactor during the growth phase of the microorganism ...
Comparison of oxygen mass transfer coefficient in simple and extractive fermentation systems
(ELSEVIER SCIENCE SA, 2009)
Aeration and agitation are important variables to ensure effective oxygen transfer rate during aerobic bioprocesses: therefore, the knowledge of the volumetric mass transfer coefficient (k(L)a) is required. In view of ...

Effect of volumetric oxygen transfer coefficient (kLa) on ethanol production performance by Scheffersomyces stipitis on hemicellulosic sugarcane bagasse hydrolysate
(2016-08-15)
Experimental evaluation of the effect of the agitation speed and aeration rate (measured by kLa) and energy required for ethanol production using sugarcane bagasse hemicellulosic hydrolysate (SBHH) by Scheffersomyces ...
Reassessment of the estimation of dissolved oxygen concentration profile and K(L)a in solid-state fermentation
(ELSEVIER SCI LTD, 2000)
Oxygen mass transfer in aerobic microbial growth systems is often a limiting factor for optimal growth and productivity. Oxygen mass transfer has been widely studied in submerged fermentations but has attracted as yet ...

SO2 influence on the K/La2O3 soot combustion catalyst deactivation
(Elsevier Science, 2008-04)
In the present work, K/La2O3 was prepared and tested as a potential catalyst to be used in a diesel engine exhaust. The soot combustion activity was evaluated by TPO, and the NOx - catalyst interaction was studied using a ...
Determinación de coeficientes de transferencia de calor y masa en un agitador rotatorio para utilizarlo en procesos fermentativos
(Universidad Nacional de Colombia, 2001)
En este trabajo se determinaron los coeficientes volumétrico de transferencia de oxígeno (kLa) y global de transferencia de calor (Ua) en matraces sometidos a la acción de un agitador rotatorio provisto de una cámara de ...
