Following the 2nd course on introduction of analytical methods in ethanol production from cassava, the 3rd course on introduction of Bioethanol production technology from cassava using Very High Gravity – Simultaneous Saccharification and Fermentation technology was held in FIRI from 20-24 August, 2018. 20 Participants from bioethanol- producing companies in Vietnam such as Vietnam Central Bio-fuels JSC, Tung lam Biofuels JSC, Orient-BioFuel, Hanoi Liquor Joint Stock Company joined the course.
The 50 lpd pilot plant of ethanol production from cassava
The 3rd course focused on practical experiments at the FIRI pilot plant of bioethanol production from cassava using very high gravity – simultaneous saccharification and fermentation technology. First, participants were equipped with theories in this field through lectures on ethanol fermentation technology, technological procedure of bioethanol production from cassava using very high gravity – simultaneous saccharification and fermentation, ethanol distillation, dehydration & safety of bioethanol production process by lecturers from FIRI, Hanoi University of Science and Technology and Institute of Natural Products Chemistry. Participants also listened to experiences of experts from Vietnam Central Bio-fuels JSC on treatment of waste water and byproducts. Besides, participants were introduced with operation process and conducted bioethanol production together with their supervisors at the FIRI pilot plant, including liquefaction, simultaneous saccharification & fermentation, distillation and dehydration. At the same time, participants also collected samples during the process to identify ethanol, acid content, inverted sugar, total counts of yeast cells in the culture and analysis of volatile compounds in ethanol products.
Carrying ethanol production experiments in FIRI pilot plant
After finishing experiments in the pilot plant, participants and lecturers discussed the results of these experiments and shared experiences in their factories in the review day. FIRI is willing to support bioethanol-producing factories in applying this new technique in the factories and offers these companies to use FIRI pilot plant to experiment their ethanol products. At the end of the course, participants had a field trip to Hanoi Liquor Joint Stock Company, one of the biggest ethanol -producing companies in Vietnam.
