How to turn lubricating waste oil into energy?

Waste lubricating oil can be recycled into the diesel and widely used in various kinds of engines and generators or used as clean industrial heating fuel.And Doing Company’swasteoil distillation plant has good performance inrefiningwaste lubricating oil into good quality diesel. Following is the general refinery process of our waste oil distillation plant to convert waste lubricating oil into diesel.

Waste lubricating oil materials

First step: dewatering

Normally waste lubricatingoilcontains 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 waste lubricatingoilin the form of vapor, to ensure the final diesel extracted from waste lubricatingoilhas 0 water content.

Second step:deodorizing

Different from waste pyrolysis oil, during the early stage of oil distillation, the oil produced from waste lubricatingoilis 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.

Third step: purification and decoloring

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.

Fourth step: decoloring

In order to keep a good oil color, decoloring agent is used into our waste oil distillation machine to further remove the oil color, after that we will get final diesel. I believe now you can well understand how Doing’s wasteoil distillation plant convertswaste lubricating oil into diesel-the treasure for human beings .
