In the realm of waste oil recycling, having a clear understanding of the applicable waste oil types is crucial for selecting the right recycling equipment. DOING used oil refinery plant is a powerful solution capable of handling various kinds of waste oils. Here is a look at the types of waste oils that can be effectively recycled using DOING used oil refinery plant:

the recyclable waste oil types Waste oil that can be recycled through DOING used oil refinery plant

1.Waste Motor Oil:

The most common type of waste oil, used motor oil in vehicles degrades due to exposure to high temperatures, contaminants, and chemical reactions. Our DOING used oil refinery plant can effectively purify used motor oil, remove impurities and restore its quality so that it can be used as a raw material for new lubricants

2.Waste Lubricant Oil:

Waste lubricating oil from machinery or industrial processes is discarded because it loses its lubricating properties and becomes contaminated during use. Our DOING used oil refinery plant can separate impurities, improving the performance of the lubricating oil which can be reused in various applications.

3.Waste Engine Oil:

Engine oils from heavy machinery include those used in large industrial machinery such as construction equipment. Our DOING used oil refinery plant can separate contaminants from waste lubricating oil and regenerate it into high-quality lubricating oil or other useful petroleum-based products.

4.Transformer Oil:

Waste transformer oil from equipment such as transformers and capacitors, which mainly come from power systems, is often contaminated with moisture or debris. Our DOING used oil refinery plant can efficiently remove harmful contaminants, making the oil reusable for transformer maintenance.

5.Waste hydraulic oil:

Waste hydraulic oil is often found in the hydraulic systems of construction machinery and industrial equipment. Our DOING used oil refinery plant can precisely distill waste hydraulic oil, extracting valuable components and purifying the oil to meet the required quality standards for reuse.

6.Crude oil/ pyrolysis oil:

Tires/plastic/oil sludge pyrolysis oil obtained by pyrolysis equipment. The refined pyrolysis oil expands the scope of application and can be used not only for boiler heating, diesel generators, but also for heavy machinery, such as tractors, trucks, ships, etc.

Waste oil to diesel solution DOING used oil refinery plant

DOING designs two types of used oil refinery plant: traditional acid-base washing type and new catalyst type, with various processing capacities, such as 0.1/0.51/3/5/7/10/14 TPD. Following is the general process flow of DOING used oil refinery plant. The plant is at high automation degree and it is very easy to operate.

1.Heat the heat transfer oil with the thermal oil boiler.

2.The heat transfer oil flows into the coil in the distillation reactor and heats the waste oil in the distillation reactor.

3.When the waste oil is heated to reach a certain temperature, the reactor is directly heated with fuel. As the temperature increases, the waste oil produces oil and flows into the buffer tank. The odorous light components and water in the waste oil can be distilled and collected into the smelly fraction oil tank and then separated from the good quality diesel, which can ensure the good quality of the final fuel.

4.① The oil and gas are cooled into oil by the cooling device and then purified by the traditional acid-base washing type waste oil refining device. ② The oil and gas from the buffer tank enter the new catalytic tower, where the large molecule oil and gas are decomposed into smaller molecules and purified by DOING patented catalyst. The small molecule oil and gas enter the cooling system through the catalytic tower and are cooled into liquid oil.

5.The liquid oil after distillation processing is further decolored and purified with the decoloring reactor and filters to be final product-diesel fuel.

6.After distillation, the residue with main component bitumen can be extracted by the asphalt pump.
