Equipment For Making Biodiesel

The Equipment For Making Biodiesel is used to chemical industry field, it makes bio-oil into biodiesel. The production steps are as follows:
1. Preprocessing section of bio-oil: when heated to 65-70a , bio-oil is leached to remove impurities.
2. Drying section: bio-oil without impurities is dehydrated and dried.
3. First esterification reaction: adding bio-oil dehydrated to methanol including 3% sulfuric acid, first esterification reaction starts, and it will take 1.5a 2.5 hours.
4. Second esterification reaction: this esterification reaction will take 9a 12 hours, temperature must be 65-70a .
5. Vacuum drying section: Second esterification reactants are dried with vacuum, removing moisture, reducing water content below 3%.
6. Distillation section: with O.O85-0.09Mpa vacuum state, second esterification reactants after vacuum drying section are heated to 220a , biodiesel forms by steaming. Then cooling biodiesel to be liquid, the liquid biodiesel is just finished biodiesel.
7. Methanol fine-distillation: after biodiesel is isolated, the remaining methanol liquid is distilled to form methanol under 60-70a . Methanol cooled may reuse.
Bio-oil may be plant oil, animal oil or high acid-value waste oil.
