DIR series Used oil refining equipment

DIR series Used oil refining equipment There are non-hydrocarbon, alkene, polycyclic aromatic hydrocarbon, metal hydronium, impurities, metal particles, asphaltene and colloid etc. harmful materials existed in used oil.These harmful substances are mutually as initiator,providing reagent and catlyst to each other.They’re oxidating, polymerizing under light,certain temperature,oxygen,the invariability of oil is destroyed and the oil appear as dark color and depositing.

Our company developed a kind of alkalic composite catalyst,in the process all the harmful substances are selectively treated under catalysis.They are polymerizing,shielding,passivating and then discharged as residues to have destablizing factors removed from oil to produce qulified base oil.

This technology is different from traditional sulfuric acid distillation treatment and hydrotreatment.The residues produced by traditional distillation treatment technology is very harmful to environment.And the recycled oil from traditional process has odour and easy oxidation.Our process is firstly catalyse the used oil including gasoline,diesel,gas engine oil,diesel engine oil,and other lube oil no matter mineral or synthetic,then distill under vacuum to make high qulity regenerated base oil without secondary pollution.This technology is high automatic,the operation is easy,no complicate operation control,low labor intensity only 1-2 persons required.
