Used Engine Oil Refining Machine
Used oil, or & acute;sump oil& acute; as it is sometimes called, should not be thrown away. Although it gets dirty, used oil can be cleaned of contaminants so it can be recycled again and again. There are many uses for refined used oil.
There are three processes to refine used engine oil to base oil in China.
Acid Process
Acid used oil recycling/reprocessing is old and popular.
Low Capital investment,very simple process.simple to operate, no advanced instruments, no skilled operators required.
Add sulfuric into waste oil, acid sludge and acid gas emission which adds heavy pollutants to the environment.
Now is banned by government
Activity clay /flocculation and filtration process.
No acid is required,but very high clay consumption, high chemical cost ,inconsistent quality. Need to add three chemicals at least,
1.water glass(Na2O.mSiO2 ,2%--),---300USD per ton, usage 2%--6USD
2.TEPA(Tetraethylenepentamine)C8H23N5,1-2%) ---8000USD per ton,usage 2%--160USD ,only produced by Japan and USA.
3.activity clay(25%) ---330USD per ton---usage 25%---82USD
4.May add NAOH, Hydrogen Peroxide etc,
Total chemical cost:248USD for refine 1ton waste engine oil.
Process is dependent on a particular type of clay which may not be available from all the sources.Disposal of large quantity of spent clay is a environmental problem.Regeneration rate is lower than 75%
