How to dispose of oil sludge?

Large quantities of oil sludge is generated in the process of oil extraction, and can be divided into surface oil spill, onshore sludge, tank bottom sludge and refinery sludge according to the formation of the sludge. Due to the diversity and complexity of the oil sludge, most of the oil sludge is a mixture of water, mud, oil and other impurities, which is more difficult to treat. The oil sludge contains not only petroleum resources, but also a large amount of radioactive elements. Therefore, from the economic and environmental protection point of view, it will be an inevitable trend to treat oil sludge in a harmless and recyclable way. But how to dispose of it?

At present, the main technologies are quenching-mechanical separation, solvent extraction, freezing/thawing, microwave radiation, incineration, etc. However, these technologies have certain limitations to ensure the treatment effect, resource recovery and harmlessness. Therefore, DOING company has developed oil sludge pyrolysis plant, which adopts low temperature pyrolysis technology with environmental protection equipment. Now, let's take a look at the detailed processing steps of DOING oil sludge pyrolysis plant.

First, put the oil sludge into the pyrolysis reactor of the oil sludge pyrolysis plant, if it is a liquid sludge, pump it into the pyrolysis reactor, and then close the inlet and outlet doors.

Next, heat the pyrolysis reactor with coal, wood, gas, oil or any one of other fuels to convert the oil sludge into oil gas.

Then, the oil gas will be cooled by the condensation system. After that, the pyrolysis oil gas will be turned into liquid oil and pumped into the tank.

And then, the tail gas produced by pyrolyzing process can be purified and recycled for use as fuel to assist heating the pyrolysis reactor.

At last, the flue gas after combustion of the fuel and tail gas is effectively treated by desulfurization & purification tower to meet the environmental protection standards.

In summary, our DOING oil sludge pyrolysis plant can convert oil sludge into fuel oil with no secondary pollution. It is one of the best ways to recycle oil sludge. What’s more, DOING oil sludge pyrolysis plant can also dispose of waste plastic, waste tires, waste rubber, MSW, etc. If you have any questions about our plants, please feel free to contact us, our professional project manager will answer for you.
