Mini Oil Refinery to Make Clean Diesel from Used Oil use cracking technology to recycle diese fuel. Pyrolysis is a petroleum refining process in which heavy-molecular weight hydrocarbons are broken up into light hydrocarbon molecules by the application of heat and pressure, with or without the use of catalysts, to derive a variety of fuel products.
The recovery rate can reach 93-95%. Gasoline 2-5%, diesel fuel 85-90%.
Flow Chart:
Working Process:
1.add 1.5%-2% liquid catalyst, mix with waste oil completely, the function of catalyst is breaks carbon-carbon bonds to turn heavier hydrocarbons into lighter ones. the catalyst will be removed together with sludge after distillation.
2. heating, there are two methods heating system, one is diesel burner heating,another is electromagnetic heating system,you can check the following information to check the details
4. further-treatment part, the output oil through adsorption chemical for making the color better and remove sulfur to 400-800ppm, if you want to less sulfur content, you can choose our SR model solvent extraction machine, which can change the color to water color and remove sulfur to 50-100ppm.
3. cooling, there are two groups of condensers, one for water and gasoline, another is for diesel oil, we cool the gasoline and diesel separatly for increase the diesel oil flash point.
High recovery rate: 87%-95%, including 3%-5% gasoline, and 85%-90%diesel

YJ-DSL series is suitable for used engine oil, motor oil, heavy fuel, bunker oil, oil sludge, crude oil and pyrolysis oil to clean diesel. After the recycling by our machine, the clean diesel can be reused on cars, ships, trucks, generators, farm machinery and so on directly.

Customer's comments on us

FAQ of Mini Oil Refinery machine to Make Clean Diesel from Used Oil :
1. Warranted?
-Yangjiang promise the machine is 100% brand new, we will provide 12 months quality guaranty from the time machine starts running at the buyer’s site.
2. Installation and training:
-Yangjiang provide 20-30days free installation and training.we will dispatch 1-2 engineers go to buyer’s factory for installation, testing and commissioning the machine, also train or provide any other technical assistance.all expenses for visa, accommodation, round-trip air ticket and lodging shall be borne by the Buyer
3. what’s the function of regenerated output diesel oil?
-YJ-DSL series can recycle different kinds of waste oil to clean diesel oil,the output diesel oil with flash point 60degree,Cetane index is 54, and sulfur content is about 400-1000ppm, you can add our solvent extraction machine to reduce the sulfur to 50-100ppm.the output diesel oil can be reused for generator,burner, ship or heavy machines, or construction machines directly.
4. What kinds of used oil can be recycled?
-YJ-DSL machine can treat used engine oil, plastic oil, tyre oil,lubricant oil and the oil from car repair shop, machines,
ship,water pump etc.
5.What kinds of chemical will use?
-We use liquid Catalyst, which react with the waste oil before distillation.The catalyst is safe to use, it won’t cause machine coke, Help to get better diesel color and diesel smell, lower sulfur content and pour point. Many people use solid catalyst after distillation, we use it before, but the problem is the catalyst is easy to block or coke when hot oil vapor through the solid catalyst.
6. why we cooling the gasoline and diesel separately?
-there are two groups of condensers, one for water and gasoline, another is for diesel oil, we cool the gasoline and diesel separat ely for increasing the diesel oil flash point.
