High Recovery Rate Used Engine Oil Purification And Distillation Equipment

recovery rate: The recovery rate base oil of this machine is more than 85%.

2. Additive and production cost: The additive cost is about US$25-US$30 to refine 1000Liter waste oil.we will send all specification to you when you make the order.

3. How to deal with the residue: The final residue is semi solid and can be processed by our DDRseries machine to get diesel or you can use the residue as fuel( mixed with diesel to sell or as fuel for boiler).

4. Why we need to add the additive: Additive will keep the recycled oil stabilization, avoiding the recycled oil oxidate and color change back to black if u wanna storage more than half year.Additive can help the oil recycled in a shorter time. So the recycled oil from our machine will keep yellow at least half  year or one year.( But the additive is not necessary, if not use it)

5. Why the machine need work under vacuum condition: The machine work under negative pressure, the boiling rage of the used oil is lower under high vacuum condition, if without vacuum unit, the oil will crack when temperature up to 420-450 degree( and the oil will become to diesel when temperature is 450 degree). The vacuum system can guarantee the whole system in high safety, the explosion won’t be happen.

6. Treated oil analysis(take the waste diesel engine oil for example): During processing, harmful substance removed, but the base oil and the existing additives are basically remained, so the invariability, antioxidation, de-emulsibility ect. better than the ordinary base oil. Below is a test report of a recycled oil sample produced from domestic used engine oil. Different countries’ black engine oil is a little different. Welcome to visit us, and take back the final base oil, oil residue and the black engine oil to your country to check by yourself according to your country’s standard.
