Quality parameters analysis in a bioethanol plant can involve measuring and analyzing various parameters to optimize the production process:
Temperature
The ideal temperature for bioethanol production can range from 27.5–37.5°C. For example, the optimum temperature for producing bioethanol from broken rice was 28°C.
pH
The ideal pH for bioethanol production can range from 4–9. For example, the optimum pH for producing bioethanol from broken rice was 4.5.
Yeast loading
The ideal yeast loading for bioethanol production can range from 20.5–21 g/L.
Fermentation time
The ideal fermentation time for bioethanol production can range from 48–48.1 hours.
Rotation rate
The ideal rotation rate for bioethanol production can range from 80–120 rpm.
Microwave power
The ideal microwave power for saccharification can range from 200–400 W.
Reaction time
The ideal reaction time for saccharification can range from 10–20 minutes.
Catalyst concentration
The ideal catalyst concentration for saccharification can range from 0.5–1.5 g.
Solvent volume
The ideal solvent volume for saccharification can range from 20–40 mL.
The concentration of bioethanol and residual sugars can be determined using High Performance Liquid Chromatography (HPLC).
