Waste oil can be refined into valuable diesel oil through catalytic cracking and high temperature distillation technology. It is a method of separating mixtures based on differences in volatilities of components in a boiling liquid mixture. After distilled by the distillation plant, the oil may have dark color with bad smell, then we suggest to deep purify the oil, with Huayin matched color and smell removal system, you will get clean diesel oil as final products with beautiful light yellow color.

Waste oil refining plant distills the incoming crude oil, pyrolysis oil, waste oil or lubrication oil into useful products such as diesel oil and fuel oils, gasoline or petrol, jet fuel, etc, the oil yield will be 85%-90%, the by-products are 10%-15% slag and syngas.
