Ⅰ. Used Engine Oil Recycling Machine Process Principle

the technology of used engine oil recycling machine adopts domestic advanced decompression thin film molecular flash evaporation technology. under high vacuum conditions (absolute pressure 10Pa), high-viscosity lubricants can be distilled out at a lower temperature, and high-temperature cracking and polymerization are also reduced., Equipment blockage and other problems. No secondary pollutants such as acid slag, waste acid and waste water are generated. It is a clean, environmentally friendly, and appropriate investment regeneration process.

Ⅱ. Introduction for High Vacuum Molecular Distillation Technology In Used Engine Oil Recycling Machine

2.1 Used engine oil recycling machine with high vacuum molecular distillation technology can convert used engine oil to diesel and base oil. and its technology parameters are as following:

(a) the temperature in the first distillation is up to 140~170℃, the pressure is about 200~1500Pa.Product is gasoline and diesel.

(b) the temperature in the second distillation is up to 170~210℃, the pressure is about 30~100Pa.Product is light lube base oil.

(c) the temperature in the third distillation is up to  210~250℃, the pressure is about 1~20Pa, Product is heavy lubricant oil base oil, the residue can be used as the fuel. in the process of distilling the waste lubricant oil, it will not go through the chemical reaction about pickling, alkaline cleaning, decolorization and precipitation, and no discharge of sodium salt or decolorant, so there is almost no pollution to the environment. The distilled base oil can be made into new lube oil after add suitable additives, its flash point and viscosity can meet the national standard.

2.2 Economic Benefits

(a) 8% light oil

(b) 76% the heavy lubricant oil or the light diesel

(c) 13% resins or heavy oil

(d) High quality recycling oil, it will not be oxidized or discolored with air contact.

(e) Low cost and high efficiency, the catalyst cost in dealing one ton waste engine oil is about $30.

(f) High automation and uncomplicated operation, it can be operate with only 1 or 2 persons. the time for learning is about 3 to 4 days.

3. Technical Features of waste oil distillation machine

the boiling point under high vacuity is lower than usual. It takes use of multi- level high vacuum distillation technology, and our company acquired different dewatering temperature and different distillate in researching the mineral oil, this provide us related parameters in separating light and heavy oil under the high vacuity. since the boiling point is much lower in the high vacuity, so the molecule will not degraded or chain broken. the end oil can not only make the
