waste oil to diesel plant

Waste Oil to Diesel Plant

Mineral waste lubricating oil sources, particularly engine oils, have garnered significant attention as a promising recycling and alternative energy source. This resource is renewable, widely available, and has been proven to be a cleaner and more environmentally friendly fuel option compared to fossil sources. Recycling lubricating oils can involve repurposing them as lubricants, reusing them as fuel, or converting them into diesel-like fuel. The production of diesel-like fuel from various waste oils, including industrial and engine waste oils, wood pyrolysis oils, fresh and waste fats, and vegetable oils, represents an excellent approach to creating sustainable alternative fuel sources. These waste materials, such as industrial and engine waste oils, wood pyrolysis oils, fresh and waste fats, and vegetable oils, have been proposed as valuable pyrolysis raw materials for the generation of gasoline and diesel-like fuels through recycling processes.


PPGT-DF Waste Oil to Diesel Plant is designed to crack the long chain hydrocarbons of waste motor oil into valuable diesel fuel and some byproducts such as light gas oil, light hydrocarbons, water, and asphaltene sludge. With PurePath exclusive fractionating and ultrasonic desulfuring technologies, the diesel which is produced by our distillation plant is able to meet Euro-V related standards

PPGT-DF Waste Oil to Diesel Plant is able to convert different types of waste oil feedstock into diesel fuel and other valuable byproducts, such as waste motor oil, waste gear oil, waste crankcase oil, waste hydraulic oil, tire/plastic pyrolysis oil, slop oil, etc. PPGT-DF series helps relieve energy crises as well as create profits with a reasonable operation cost.

The primary product of this process yields 80%~85% oil that meets commercial standard diesel specifications. Meanwhile, the byproducts consist of light ends, water, and oil sludge/residue. Light ends can be utilized as a fuel oil for burners that supply cement factories, glass factories, ceramic factories, electric power factories, steel-making factories, boiler factories, and other similar facilities. On the other hand, the oil sludge/residue can be repurposed for asphalt production.

The production will be started with a project kick off meeting; and then designing process for P&ID, process simulation, equipment selection, sizing and heat exchang calculation; and followed by manufacturing and equipment testment; then whole plant assembly for testing and then disassembling for shipping.

The waste are usually composed by gas, water, oil sludge/residue. 

The gas will be purified for emission or recycled as heating fuel; 

The water can be filtered and purified as cooling water; 

The oil sludge can be used for burning or as material for making asphalt or road constructions.
