What’s the best way to recycle used engine oil?

As environmental awareness grows and the demand for resource recycling rises, used engine oil recycling has become a field of concern. At present, there are many used engine oil recycling methods on the market, each with its own characteristics. Next, we will introduce these methods in detail.

Currently, there are several main methods for used engine oil recycling:

Used engine oil recycling methods

1. Filtration method

Filtration method is a basic and common waste oil recycling method, which is suitable for removing large particle impurities in used engine oil. The process includes separating impurities through filters such as gauze or fine mesh, or using centrifugal force to separate oil.

2. Sedimentation method

The sedimentation method allows the waste engine oil to settle naturally, and then separates the clear upper oil. It is suitable for situations where there are fewer impurities in the oil.

3. Distillation method

The distillation method is currently the most advanced waste oil recycling technology. It heats the used engine oil to evaporate it into oil gas, and then condenses the vapor into liquid through condensation. This method can efficiently extract superior quality non-standard diesel and remove most pollutants. And it can be further catalytically refined and decolorized to improve the quality and color of the recovered diesel oil.

4. Chemical treatment method

The chemical treatment method converts or decomposes the harmful components in the waste oil by using chemical reagents to react with the used engine oil. This method is suitable for used engine oil containing heavy metals and toxic substances, but it requires high technical requirements and costs.

Comparison of Waste Oil Recovery Methods

Combined with the above analysis of waste oil recycling methods, you can choose a suitable used engine oil recycling method according to your actual situation. We sincerely recommend the distillation machine as the best used engine oil recycling way for its high efficiency, environmental protection, and high recovery rate.
