DIR Oil refining equipment

DIR Oil refining equipment, oil refinery plant, atmospheric and vacuum distillation unit

DIR is a kind of vacuum distillation oil refining equipment for reclaiming of used motor oil, this kind of oil refinery plant added catalyst chemicals for separation of harmful materials of used oil and de-coking of the system. The used oil can be cleaned and regenerated in to different viscosity high quality base oil.

This system could recycle different kinds of used oil including engine oil, hydraulic oil, machine oil and other lubricants. The light fraction is completely removed and the recycled base oil is of good viscosity, good color, odor, and high lubricating properties.

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 catalyst 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 qualified 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 odor 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 quality 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.
