used oil cleaning 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 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 alkaline 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 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 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.1.Working principle of used oil cleaning equipment
This equipment adopt physicochemical actions to polymerize, passivate, absorb and eliminate impurities and harmful contamination. We research a new chemical alkaline complex catalyst, which can restore and regeneration the Waste oil to clean oil, save the component of the oil. 2. Advantage of used oil cleaning equipmentIt's easy to produce waste residue and bad smelling by traditional vitriol distilling, which will bring potential secondary pollution, moreover, it's easy to change the color to black and produce the odor due to the recycled oil react with the oxygen. But after we use the alkaline complex catalyst refines the oil, the recycled oil haven't change the color and haven't create the odor. What's more important, you can use the resid to be as the fuel to heating the oil, without any pollution. And the equipment is easy to operate, only 1-2 workers can control the equipment. 3.

High quality refined oil, no any discoloration caused by oxidation, no any bad smelling. e. Low cost contain: 1) only need the catalyst chemical, the cost is less than US$30 to refine one ton waste oil. 2) Heat consumption: 105 kcal per ton waste oil 3) Power consumption: 40Kwh to recycle 1 ton waste oil f. High degree of automation.
4. Working Principle of used lubricant regenerating plantA proposal for processing waste lube oil and industrial oils, using high vacuum distillation technology is presented here. The various steps involved in the projects are given below. Step1: The waste oil is pre-treated and then send to chemical processing kettle and react with catalyst. Step2: This waste oil is approx 130 degree at 0.098Mpa to have water and some light fractions separated. Step3: The temperature is keep rising up to 200-230degree at 500Pa , the lighter fractions such as gasoline, diesel are distilled and cooled and then stored in diesel receiving tank. Step4: The undistilled waste oil subjected to high vacuum, medium temperature in the heated distillation plant, the light base oil fraction is distilled and cooled and then collected in the light base oil tank( above 240degree and at a pressure of 300Pa). The distilled oil will have a viscosity of higher than SN100 at ambient. Step 5: The undistilled waste oil subjected to high vacuum, high temperature in distillation plant, the heavy base oil fraction is distilled and cooled and then collected in the base oil tank ( above 290degree and at a pressure of 100Pa). Distilled oil approximately higher than SN150 in viscosity). Step6: The distilled oils are clean oil generally no need further treatment, they are going to be blended with additives to get finished oils for the automotive and industrial applications. Step7: The final residue is semi solid at ambient and can be processed for manufacturing asphalt, finished to make off-speck heavy fuel oil or to make greases for slow moving equipment.
