YJ-TY Lube Oil Recycling Plant for Used Oil
Recycle all industrial used-oil to virgin base oil API Group I
The Importance of Recycling and Reusing Used Oils
Lubricants are primarily composed of base oil, which makes up about 70% of the formula. The remaining 30% consists of oil additives that play a crucial role in enhancing the performance of the oil, such as protecting the engine against wear, corrosion, and keeping it cool and clean. These additives include dispersants, anti-wear agents, oxidation inhibitors, and viscosity index improvers. By combining base oil with these additives, new lubricants such as hydraulic oil, gear oil, and engine oil are produced.
Used oil, despite being dirty, remains a valuable resource. It retains lubricating and heat value, meaning it can be re-refined into base lube oil, reprocessed as fuel oil, or used as feedstock for producing other commercially valuable products. Proper handling and recycling of used oil not only prevent environmental contamination but also conserve a vital non-renewable resource.
Application of Lube Oil Recycling Plant for Used Oil
YJ-TY Lube Oil Recycling Plant for Used Oil is particularly suitable to regenerate used engine oil including diesel engine oil, gasoline engine oil,motor oil,ship engine oil, truck oil, and used hydraulic oil, other used machinery lubrication oil into SN80,SN100,SN150,SN300,SN 500 base oil.
YJ-TY Lube Oil Recycling Plant for Used Oil can recycle the waste oils to yellow base oil, It not only removes the impurities, water, and acid matter, organic and inorganic acid effectively, but also can remove carbon particulate matter and peroxides. In gas/diesel engine oil, bitumen and colloid and other sludge can be removed similarly, and it can change the color to golden color, remove bad odor. the output base oil can be reused for low engine or add different oil additive into it for producing hydraulic oil, gear oil, lube oil or engine oil.
Technology Description of Lube Oil Recycling Plant for Used Oil
YANGJIANG use vacuum distillation to remove the contaminants in the used oil, it will reduce the pollution and recycle the oil for reuse. Vacuum distillation is a method of distillation that the pressure above the liquid mixture to be distilled is reduced to less than its vapor pressure (usually less than atmospheric pressure), causing evaporation of the most volatile liquids (those with the lowest boiling points).The whole process is physical distillation, no acid and no chemical will be contained in clean oil. And the machine will distill out what the used oil contains, it won’t change the oil quality and components.The base oil recovery rate is form 75-85% according to the raw material quality, color index 1-1.5

Process Brief Description of Lube Oil Recycling Plant for Used Oil
- Reaction with Chemical: we need add catalyst(alkaline chemical) to neutralize waste oil acidity before distillation.
- Distillation Under High Vacuum: We heat the used oil under high vacuum by various heating method till all cuts be distilled out ,you can choose electromagnetic heating,fuel oil boiler/furnace heating,natural gas boiler/furnace heating,even used engine oil heating.
- Condensation and Collection of Water,Light Fuel and Base Oil : As the temperature in the distillation unit rises, various cuts are liberated corresponding to various temperatures and rise as vapors,all after the vapors to be condensed ,we can collect different products in sequence,water,light fuel and base oil.
- Base Oil Further-Treatment: For the long term storage and better stability, there are two oil further treatment options, one is clay or silica refining,Another further-treatment option is our YJ-SR Solvent Refining Equipment,which can refine base oil to meet API group 1+ specification,can refine base oil to water-white color,and greatly improve base oil quality such as viscosity index,saturated hydrocarbon etc.
- Exhaust Gas Treatment System: With Yangjiang exhaust gas treatment, the exhaust gas will be burned to oxidize and decompose the VOC compositions in the exhaust gas, so as to meet the requirements of “Overall Air Pollutants Emission Standards”.
- Base Oil Blending :If you need to blend base oil into lubricating oil,you can choose our YJ-BYL Base Oil Blending Plant ,which can mix oil additives with base oil for producing new hydraulic oil or engine oil(like 10W/40,15W/40,20W/50).
Yangjiang has been committed to solving various waste oil purification problems,in addition to the above waste oil recycling plants, we also provide other used oil re-refining plants, such as Waste Oil to Diesel Oil Distillation Plant,Diesel Desulfurization Machine,Base oil Solvent Extraction Machine,Base Oil Blending Plant,Transformer Oil Regeneration Machine
