Title: | Volumetric gas-liquid mass transfer coefficient in an external-loop airlift reactor with inserted membrane | Authors: | Kojić, Predrag Šijački, Ivana Lukić, Nataša Jovičević, Dragica Popović, Svetlana Petrović, Dragan |

All rights reserved. The effects of the inserted membrane in the downcomer of an external-loop airlift reactor, the gas sparger type (single orifice and sinter plate) and added alcohol (ethanol, n-butanol or n-hexanol) on the volumetric gas-liquid mass transfer coefficient (kLa) were studied. Due to the presence of the membrane in the downcomer, kLa did not change significantly; the differences were smaller than 10%. The highest values of the kLa were obtained using the sinter plate. It was found that the addition of small amounts of alcohol increased the mass transfer. Using our experimental results and the data of other authors, the feed-forward back propagation neural network for prediction of kLa in external-loop airlift reactors with alcohol solutions was proposed. | URI: | https://open.uns.ac.rs/handle/123456789/4966 | ISSN: | 14519372 | DOI: | 10.2298/CICEQ150622041K |
