What is oil sludge treatment process?

At present, the treatment methods for waste oil sludge mainly include incineration, solvent extraction, landfill, and biodegradation，etc. The above treatment methods will waste petroleum resources, incomplete treatment, and occupation of land and also cause secondary pollution. Now we mainly recommend the use of pyrolysis plant and distillation machine to treat oil sludge.

Next, I will mainly introduced the oil sludge treatment process of pyrolysis plant and distillation machine.

Oil sludge treatment process of pyrolysis plant  

Because oil sludge has different forms, such as solid oil sludge, semi-solid oil sludge, and liquid oil sludge. Different forms of oil sludge have different treatment processes, different feeding methods, and different equipment is needed to process.Solid oil sludge and semi-solid oil sludge can be treated with pyrolysis plant. Through a low-temperature pyrolysis process, oil gas are cracked from the oil sludge and cooled into crude oil through the cooling system. The solid oil sludge can be directly fed by an automatic feeder. The semi-solid sludge has a certain fluidity and needs screw conveyor to feed.

Oil sludge treatment process of distillation machine

Liquid oil sludge can be treated by distillation machine. The oil gas are evaporated by distillation, the oil residue is filtered out, and the oil gas are cooled into crude oil through the cooling system. The liquid sludge can be directly pumped into the distillation machine through the oil pump.

The final products from oil sludge

After the treatment of these devices, we can get crude oil, ash and water from oil sludge. The crude oil can be used directly. The ash can be filled or used as a brick-making material, which not only saves oil resources, but also solves the problem of environmental pollution.

Therefore, different forms of oil sludge have different treatment processes. We will recommend suitable equipment according to your oil sludge situation. If you have any questions, please contact us directly.
