Biodiesel Process Flow Diagr.
2 likes597 views
The document is a process flow diagram for a proposed biodiesel plant. Raw materials like waste cooking oil, animal fats and processed fatty acid distillate are pre-treated and purified. They are then processed using a transesterification reaction with methanol and KOH catalyst to produce biodiesel and glycerine. The biodiesel undergoes further purification and quality control. Byproducts like glycerine and fertilizers are also produced. Effluents are treated in wastewater and sludge treatment systems before being discharged.
