What is used oil recycling process?

Used oil is a kind of high pollution substance, which needs to be treated properly. The usual used oil recycling process is: heating - catalytic pyrolysis – cooling - diesel collection.

The main sources of used oil are lubricating oils, hydraulic fluids, heat transfer liquids, buoyancy liquids，etc.

Used oil to diesel oil

Used oil may cause environmental damage if it is dumped underground or discharged into water currents, including sewers. This can lead to groundwater and soil pollution. Therefore, recycling these used oils is not only a recycling of resources, but also has a significant positive impact on the environment.

Pollution from waste oil

Used oil is contaminated with physical or chemical impurities due to its use. In general, waste oil contains many impurities, such as dust, metal chips, water or chemicals.

Used oil recycling process is below:

1. Firstly, impurities in used oil are separated.
Usually, people use distillation to do this. When the used oil is heated to a certain temperature, the used oil begins to boil and evaporate. The oil gas are evaporated and the remaining impurities are separated.

2. The vaporized oil gas contains some macromolecular heavy oil, which needs to be catalytic pyrolysis into light oil, which is called diesel oil.

3. Cooling the oil gas to form liquid diesel oil.

4. Collect diesel oil.

Although the whole used oil recycling process seems simple, it is not recommended to recycle used oil into diesel at home. There are many variables to control in this process, and operating on your own can be dangerous.

Used oil distillation machine is in operation

The used oil distillation machine produced by DOING company adopts advanced distillation technology to recycling used oil. Used oil distillation machine can not only process used oil, but also can process thermal decomposition tire and plastic oil. And the whole process of recycling without pollution to the environment.

Using used oil distillation machine to recycling used oil is the most ideal way at present.
