Ethanol concentration of fermented broth by ohmic-assisted hydrodistillation

In this research, ohmic-assisted hydrodistillation (OAHD) was used as an advanced hydrodistillation (HD) technique and compared with traditional HD in concentration of ethanol from industrial fermented corn beer. OAHD method was quicker, more economical, more sustainable and with a better ability of process control than HD method. Such advantages can make OAHD as an alternative technique for the production of larger quantities and higher concentrations of ethanol by scaling up the equipments and process in biofuel factories, instead of the conventional HD process.
