The bio-ethanol training system simulates a pilot plant for bio-ethanol production out of cellulosic or starch-based material through fermentation. Bio-ethanol is one of the renewable fuels nowadays that can substitute fossil fuels or even when it’s mixed in specific portions with gasoline, it ensures greener and more eco-friendly fuel. Using this training unit, trainees will get to experiment and test all of the stages of which agricultural waste undergoes till it’s converted into salable fuel.

                                     
  • The bioethanol training system introduces trainees to the basic fundamentals of fuel generation out of agricultural material. Trainees will be able to test and experiment using different sources of agricultural material such as potato peels, sawdust or rice straw.
  • The training system comprises of a main tank where all of the processes take place, making it convenient in small labs and easier to comprehend by students.
  • The main tank is made out of stainless-steel material to withstand higher temperatures.
  • The tank is provided with stirrer and baffles for more efficient mixing of components.
  • The tank is provided with heating/cooling utilities to adapt with each stage temperature requirements.
  • A sight glass can be found on the tank, where trainees can monitor the process through the stainless-steel tank.
  • The process tank is insulated in order to provide more safety for the user.
  • Pre-treatment of agricultural waste is implemented within this system in order to prepare the used wastes for the next stages. The applied treatment can be physical through size reduction or chemical using acid or alkali
  • Water is added to the pre-treated wastes in order to form a mash in the main tank. All of the introduced substances can be controlled through a hopper.
  • During the mashing process the starch of the raw materials is turned into glucose. The addition of the alpha-amylase enzyme enables the liquefaction of the starch slurry, then saccharification starts by adding the glucoamylase enzyme.
  • After the previously mentioned stages, fermentation takes place by adding yeast to the main tank as well.
  • During fermentation, carbon dioxide is produced which can be detected through the mounted air lock to the tank.
  • All of the stages are governed by temperature and PH values. Hence, temperature sensors, PH meter and controllers are provided with the main tank to control all of the stages.
  • The process tank is supplied with distillation column as the produced ethanol through fermentation is diluted due to water existence. Water is separated upon temperature difference since ethanol evaporates faster than water.
  • Two temperature sensors are mounted to the distillation column to read off the temperatures and be able to adjust it to the required value needed for ethanol evaporation.
  • After ethanol evaporation, it’s passed through a condenser where it’s converted into liquid bio-ethanol once again and stored in a separate tank.
  • The distillation column is provided with bubble cap trays to provide higher performance of the distillation process.
  • The trainer contains ON/OFF switch of the trainer and emergency switch in case of any inconvenience.
  • The trainer is supplied with a schematic diagram elaborating the implemented process.
