Abstract

Oxygen transfer measurements using a dynamic method and evaluated with an appropriate mathematical model have been made on a tubular loop bioreactor. Correlations of the type used in tank systems are used to describe the influence of power and aeration rate on the mass transfer coefficient. Yeast cultures grown on hydrocarbon and glucose substrates show growth characteristics similar to conventional tank results. Model considerations for large‐scale tubular fermentors allow for the prediction of the steady‐state oxygen profiles and maximum reactor length. Combination with two‐phase flow and oxygen transfer correlations yields a design procedure for commercial scale tubular loop fermentors.
