How to clean used motor oil for diesel fuel?

With the large amount of used motor oil on the market, how to clean used motor oil for diesel fuel be reused? Our company’s used motor oil recovery equipment can meet your needs.

First of all, we need to know that the motor oil is a mineral oil, which is a kind of product obtained by vacuum distillation of heavy fractions of petroleum. We can use used motor oil recovery equipment to clean the used motor oil to get diesel fuel that can be reused. Then what is the process?

Cleaning used motor oil to diesel

1. Distillation

Distillation removes the water from the used motor oil completely, and then separates low-boiling fuel oils such as gasoline and diesel. Distillation requires the use of a standard boiler steel. The distillation steel was heated to carry out distillation. The gasoline is distilled at 180 °C, and the fraction of 180 to 360 °C is diesel, leaving asphalt as residue.

2. Cooling

In order to condense the steamed oil gas, we also need a condensing device. Our company uses circulating water to cool, and the cooling water is not in contact with oil gas. The cooling water is cleaned and recycled without causing waste of water resources.

3. Decolorization

Most of the impurities in the used motor oil are separated and precipitated by the action of the catalyst A. In the catalytic A process, a chemical reaction occurs between the catalyst A and the colloidal, asphaltic impurities in the waste engine oil to precipitate the waste residue.

Under the action of the first catalyst A, a partial precipitation will occur. The fourth catalyst B deodorization step can neutralize the precipitate and remove the heavy color of the diesel fuel to make the oil clear and bright.

5. Purification

Purification is to further make the color bright of the fuel oil. “Catalyst adsorption” is an optional purification system. The principle is to use a catalyst C to adsorb impurities in the oil, and then filtering the catalyst C. At last, you can get a bright color dieel fuel as end product.
