oil recycling equipment to base oil through vacuum distillation
overview：This machine can treat a variety of waste lube oil ,get high quality base oil and a small amount of gasoline and diesel through vacuum distillation.after pretreatment,waste oil pumped into the distillationKettle,heat to working temperature,can get the base oil ,gasoline and diesel we required.
When reaction complete,stop heating,remove residue from the bottom of the tank,then the machine can be used again.the production cost is low,and the base oil is high quality.this is the most advanced technology in the world in the waste oil recycling line,and suitable for large-scale industrial production.
Systems of equipment
① pretreatment system：waste oil will be pumped into the distillation kettle after pretreated.
② distillation system:through buring coal,gas or fuel oil to make the oil in the kettle up to the working temperature.this system equipped with stirring system and insulation system.
③ Cooling system::the gaseous hydrocarbon will be cooled into liquid base oil.gasoline and diesel.
④ Oil storage system:the base oil,gasoline and diesel get from cooling system storage here,then pump into the storage tank.
⑤ Vacuum system:meet the technology requiment.
⑥ Filtration system:rapidly filter out mechanical impurities in the base oil,gasoline and diesel,get the high quality base oil,gasoline and diesel.
Recovery rate
Base oil:85%~88%(index same as SN150~SN200)
Gasoline :about 3%
diesel:about 3%-4%
Oil residue:6%~8%

performance characteristics、advantage introduction
1. low cost:only cost about USD30 of Pretreatment reagent when treat 1 ton used oil.the Pretreatment reagent is basic chemical material,can buy in every country,without any restrictions.
2. easy operation: 1~2 people can easily operate the machine
3. environmental protection:the whole process is all sealed,won’t release any gas harmful to human and environment,the colloid and asphalting,carbon black in the waste lube oil are all into sludge,can be used as asphalt or fuel.
4. widely usage:can treat gasoline engine oil,diesel oil,rubber oil and other waste lube oil of the engine,also a variety of cleaning oil.
5. high recovery rate:Base oil:85%~88% gasoline3%.diesel:3-4% sludge:6%~8%.
6. Do not need acid and clay, get high quality base oil : No unsaturated composition,can storage in a long-term without change its color,also no any bad smell.
7. this is the most advanced technology in the world and suitable for large-scale industrial production.
