Can waste oil sludge from steel mills be recycled?

Waste oil sludge generated from steel mills is typically disposed of through landfilling, a method that poses significant environmental risks due to its slow decomposition rate. To make full utilization of the value of oil sludge and reduce pollution to the environment, DOING has researched a type of oil sludge recycling pyrolysis plant, which can recycle various types of oil sludge, including but not limited to steel mills oil sludge.

Generally speaking, pyrolysis is a process of chemically decomposing organic materials at elevated temperatures in the absence of oxygen. The process typically occurs at nominated temperatures and under pressure. It simultaneously involves the change of physical phase and chemical composition and is an irreversible process. During the whole pyrolysis process, we can recycle steel mills oil sludge to fuel oil, carbon black and syn-gas; the following is a brief introduction to the recycling process:

Preprocessing: Before pyrolysis, the oil sludge needs to be pretreated to remove water. This step can be achieved by centrifugation, filtration, or other methods.

Feeding and Pyrolysis: The oil sludge will be sent to the pyrolysis reactor with the oil sludge pump and pyrolysed at high temperature (generally between 400°C and 600°C) to obtain fuel oil, carbon black and syn-gas;

Exhaust gas cleaning: The pyrolysis gas, also called syn-gas, is separated and purified to be recycled. The main component of the syn-gas is bio-gas (CH4), so we can not condense and store these gases. These gases as the heating energy for the waste oil sludge pyrolysis plant and you can use exceed gases for other heating applications.

For the special characteristics of oil sludge, DOING oil sludge recycling pyrolysis plant also adopts special designs, such as the anti-coking design and the stainless steel material making, and DOING has successfully helped our customer install oil sludge recycling pyrolysis plants in Colombia to recycle coal tar oil and received good feedback on the performance of our machines. The following is the real running video of this project:

Henan Doing company has specialized in producing environmental equipment over decades and integrating technological design, research and development, machine production, sales and after-sales service in one. In addition to oil sludge, our pyrolysis plant can also recycle other solid waste, such as waste tires, rubber, plastics, solar panel, aluminum plastics, corrugated plastic sheets, etc. If you are interested in this technology, please feel free to contact DOING for more information.
