Waste oil sludge and related oil contaminants treatment way

Oil sludge is one of the main sources of pollution in the oil industry. It is a type of oily solid waste with resource recovery value generated during oil extraction, well repair, gathering, refining, transportation and storage. And during the transportation and storage, there will also generate other related oil contaminants, such as oily mud woven bags, which all can be effectively recovered.

Various oil sludge and related oil contaminants

There are different ways of oil sludge and related oil contaminants treatment, including biological treatment, chemical treatment, physical and chemical treatment, landfilling and incineration, etc., among which chemical treatment of pyrolysis is the most green and effective.

Pyrolysis refers to a method of heating oil sludge under oxygen-free and slightly positive pressure conditions to precipitate the oil and organic matter in it, and to separate the oil sludge into pyrolysis residue, pyrolysis liquid, and pyrolysis gas to achieve the purpose of resource utilization. The thermal conversion process of oil sludge is divided into two stages: The first stage is the evaporation stage. When the temperature is lower than 350°C, low-boiling light hydrocarbons evaporate from the oily sludge; the second stage is the parallel-sequential reaction stage. When the temperature exceeds 350°C, heavy oil begins to crack. At about 400°C, hydrocarbons will generate free radicals due to thermal activation, and a series of free radical reactions will occur. On the one hand, it will proceed in the direction of pyrolysis to generate small molecular hydrocarbons, and on the other hand, it will proceed in the direction of condensation to generate four products: fuel oil, solid residue and syn-gas. However, the reaction conditions are different and the product ratios are slightly different.

Applications of obtained fuel oil

The obtained fuel oil can be used as heating fuel in some heavy machineries, such as cement plant, steel plant, glass plant, brick plant, heavy oil generator, etc. And if you want to enlarge the applications and markets of fuel oil, you can also refine it to non-standard diesel with the waste oil distillation machine.

So far DOING has gained rich experience in oil sludge pyrolysis machines to help our customers recover waste oil sludge effectively and greenly and produce high grade end products. Take the most common problem occurred in the pyrolysis process-sticking to the wall-as an example, DOING researched the decoking device inside the reactor, and when the reactor rotates, the device moves to remove the existing coke, so as to reach fully recovering. In addition, DOING oil sludge pyrolysis machine will also equip the environmental protection system to avoid waste dust or gas pollution to realize greenly recovering.
