ABSTRACT:

Sufficient dimensioning of cooling and heating surfaces in bubble column reactors requires knowledge of the heat transfer coefficient under different operating conditions. The heat transfer on pipes that were suspended in bubble columns were investigated as a function of various parameters. The heat transfer is particularly strongly dependent on the gas velocity and the viscosity of the liquid. The results can be described by exponential functions. 15 refs.
