Abstract:
Ethanol is a renewable and clean biofuel mostly produced via fermentation process. The
productivity of ethanol can be increased when the ethanol was removed from the culture
broth to diminish the inhibition effect on growth rate of microorganisms. In this study, the
conventional processes and in situ removal processes were modeled based on Polymath and
Aspen Plus. During the process of in situ removal, hot air microbubbles (>78 oC) was
generated and fed to ethanol-water mixture. Ethanol, which is lower boiling point than water,
was then evaporated from the mixture into microbubbles. The ethanol in microbubbles was
removed when they floated over the mixture. The rate equations and kinetic parameters of the
formation of by-products i.e., glycerol and acetaldehyde were formulated using Polymath.
Polymath was also used to estimate the kinetic parameters with the rate unit of mol/L·hr.
These parameters were then used in Aspen Plus to estimate the increase of productivity and
energy consumption. In comparison with the conventional processes, the simulation results
showed that the productivity of ethanol from the in situ removal processes increased by 1.5%.
The energy removal at the fermenter section increased by 38.83%. However, the overall
energy consumption including fermentation and separation sections of the in situ removal
processes decreased by 9.73%.
