Ⅰ. Engine Oil Recycling Machine Application
Our vacuum distillation equipment is used for recycling base oil from used lubricant oil, contaminated hydraulic oil and black engine oil from 4S car stores etc.. It can regenerate and recycle base oil from all kinds of waste lubricating oil at high recovery rate with energy saving and environmental protection. Our vacuum distillation equipment and process are your first choice for waste oil regeneration and recycling!
Ⅱ. Engine Oil Recycling Machine Technology Principle
Our vacuum molecular distillation equipment adopts high vacuum distillation technology, atmospheric and vacuum technology to realize liquid-liquid separation by the difference of mean free path of molecular movement of different substances. The free path of molecular motion refers to the path between two adjacent collisions of a molecule. When the oil is heated, light and heavy molecules will overflow the liquid surface and enter the gas phase. Because the free path of light and heavy molecules is different, the molecules of different substances will move different distances after overflowing the liquid surface, so as to achieve the purpose of substance separation.The vacuum distillation technology not only speeds up the molecular overflow time, but also improves the oil yield.
Ⅲ.Engine Oil Recycling Machine Technology Advantages
3.1 The equipment adopts atmospheric and high vacuum separation technology, with low working temperature (far below boiling points), high vacuum degree (no-load ≤ 5pa), short heating time (in seconds), high separation efficiency, especially suitable for the separation of high boiling point, heat sensitivity and readily oxidizable substances.
3.2 The machine can effectively separate and remove low molecular substances (deodorization), heavy molecular substances (decolorization) and impurities in the used oil.
3.3 The equipment uses high vacuum scraping film evaporator, which has high separation rate, far higher than the traditional distiller. The common evaporator begins carbonizing and coking at 300 ℃, that is to say, the quality of recycled oil is obviously reduced, and the recovery rate is also obviously reduced. Because there are many impurities such as gum, asphalt and free carbon in the used oil, the high vacuum scraping film evaporator can effectively prevent these substances from coking, effectively guarantee the long-term operation of the equipment and improve the regeneration output of the waste oil.
3.4 Advantages of atmospheric and vacuum continuous production process.
It can be divided into first-line oil, second-line oil and third-line oil.
The basic way is to divide the used oil into different straight-run distillation fractions according to the boiling point requirements of different products, and then remove the non-ideal components according to the product quality standard requirements, or through chemical reaction conversion, the required components can be generated, and then a series of qualified base oil products can be obtained.
3.5 The by-products such as tail oil, residual oil, light component oil and extraction oil can be sold as industrial fuel oil.
3.6 The process adopts solvent refining instead of sulfuric acid and clay, so there is no "waste residue" discharge.
3.7 The vacuum distillation equipment investment is less, equipment construction cycle is fast, product income is high.
Ⅳ. Vacuum Waste Engine Oil Distillation Equipment Main Product Index
4.1 The major product of used oil distillation and refining is base oil. The recovery rate of base oil mainly depends on the situation of the raw material( the used lubricant oil). Generally, the best is the used engine oil from 4S car shops, and the worst is marine ship diesel engine oil.
4.2 Generally, the product yield (calculated according to the raw material without water content) produced by this process is as follows:
4.2.1 Light industrial fuel oil 5-10%
4.2.2 Heavy industrial fuel oil 8-15%
4.2.3 Base oil 70-85%
4.2.4 The quality of the solvent-refined base oil meets the HVI 100SN,250SN and 350SN standards of CNPC (Q/SY44-2009) lubricating base oil.
