Used motor oil recycling process
De-watering -- The first step of used motor oil recycling process.
Normally used motor oil contains about 5% -30% water. If the water content ＞30%， then there is no meaning to do the oil recovery. When gas temperature reach 100 degrees, keep this temperature for a while to allow all the water removed from used motor oil in the form of vapor, to ensure the final diesel extracted from used motor oil has 0 water content.

De-odoring--The second step of used motor oil recycling process.
Different from waste pyrolysis oil, during the early stage of oil distillation, the oil produced from used motor oil is milk-like which has bad odor, we also call it dirty oil. Our waste oil distillation plant can separate this small quantity of dirty and smelly oil from the final diesel and collect it into a separate oil tank.The deodor system of waste oil distillation plant
Purification and de-coloring---The 3rd step of used motor oil recycling process.
In the middle and final stage of oil distillation, the oil gas is treated by two kinds of catalyst, catalyst A and catalyst B. Function of catalyst B is to absorb impurities inside the oil gas and meanwhile remove the dark color to some extent. After processing by catalyst B, the pure oil gas will be processed by catalyst A, and function of catalyst A is to make heavy oil gas thoroughly break down. Then oil gas will flow into cooling system and condensed into diesel to be collected in the oil tank.Purification system of waste oil distillation plant
Further decoloring---The last step of used motor oil recycling process.
In order to keep a good oil color, decoloring agent is used into our waste oil distillation plant to further remove the oil color, after that we will get final diesel.3D drawing of DOING waste oil distillation plant
