Notes:
In order to make heat and mass transfer processes in bioreactors more intensive, the turbulent liquid film flow which is proposed for realization in multitubular reactors has been developed. Experiments have been carried out in tubes with smooth and rough surfaces at cocurrent gas and liquid film downward flows with a view to determine the values of the mass transfer coefficients in turbulent liquid hold-up in contact tubes. The liquid viscosity and REYNOLDS number are changing in a wide range (from 2000 to 60000).The results show that the maximum values of the mass transfer coefficients and an acceptable hold-up can be obtained in tubes with rough surfaces at high REYNOLDS numbers of the liquid film. The results of culturing yeasts on hydrolyzate in a laboratory-size liquid film fermenter are also presented.
