The equipment is used to chemical industry field, it makes bio-oil into biodiesel.

   It contains the international advanced pre-processing section, esterification process and distillation process, and it meets the European Union Standards(Patent No.: ZL200920089138.8). The prodution steps are as follows:

      1. Preprocessing section of bio-oil: when heated to 65-70°C, 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 1.5—2.5 hours.

      4. Second esterification reaction: this esterification reaction will take 9—12 hours.

      5. Vacuum drying section: Second esterification reactants are dried with vacuum, removing moisture, reducing water content below 3%.

      6. Distillation section: with vacuum state, second esterification reactants after vacuum drying section are heated to 220°C, 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. Methanol cooled can be reused.    

      Bio-oil can be plant oil, animal oil or high acid-value waste oil.

Advantages: 1. stable process pefermance

                     2. simple operation 

                     3. small investment of equipment

                     4. high conversion rate( up to 85%)

   Specifications: 5T/D---300T/D

   Pls offer the detailed processing capacity or biodiesel yield you require when inquiry.
