Advantage and Deference

Compare with Clay /flocculation and filtration process 
Clay /flocculation and filtration process.
High chemical cost
Low regenerate rate
 
A. Chemical cost 
Clay /flocculation and filtration process. 
Use three chemicals at least, 
1.water glass(Na2O.mSiO2 ,1%--),---300USD per ton, usage 1%--3USD
2.TEPA(Tetraethylenepentamine)C8H23N5,1-2%) ---8000USD per ton,usage 2%--160USD 
3.activity clay(25%) ---330USD per ton---usage 25%---82USD
   May add NAOH, Hydrogen Peroxide etc, 
For one ton waste oil treatment ,total Chemical cost 245usd at least. China does not produce TEPA, there just three main producers in the world, one is in Japan, and other two are in USA, 
 
Vacuum distillation process.TY Waste Lubricating Oil Purification and Recovery- vacuum distillation.
Chemical Cost
Chemical:1600USD per ton,usage is 1.5-2%--30USD
 For one waste lube oil treatment, total Chemical cost is just 30USD , 
 
B.regeneration rate

 Clay /flocculation and filtration process. 
Using flocculation &filtration process, only heat the oil to 140 ℃ celcius,as we knows, there are a lot of additive in the waste oil, and the additive can not be broken at 140℃ celcius, so it is difficult remove black waste oil color.that is why this process need add 25% activity clay to decolor,  fuel oil,base oil can not be separated form the waste lube oil ,so the recycling rate is lower than 70%.
 
Vacuum distillation process.YJ-TY Used Engine Oil Recycling Machine- vacuum distillation. 
Vacuum distillation process ,waste lube oil will be heated more than 320℃ under vacuum ,the highest temperature is about 350℃ under vacuum.All part of cut,such as gasoline,diesel,light and heavy base oil in the used lube oil will be distilled out completely.
 
Vacuum distillation process can broke the additive in the waste lube oil,then can decolor the waste black oil back to yellow(color standard is 1.5), also can separate fuel oil,base oil form the waste lube oil effectively and completely ,the regenerate rate is more than 85% as following:.
