Oil sludge recycling technology: Pyrolysis Machine

Oil sludge refers to a semi-solid or solid mixture formed during various industrial processes involving oil, particularly in petroleum refining, storage, and transportation, as well as in machinery operation. And in our life, the common oil sludge includes refinery sludge, tank bottom sludge, drilling sludge, machine oil sludge, pipeline sludge, etc.

To avoid the pollution generated by oil sludge, we generally dispose of oil sludge with the solution of landfilling, incineration, solvent extraction, biological treatment and pyrolysis technology. Among these treatment ways, pyrolysis technology is a cost-effective recovery way, which can not only avoid pollution, but also can recover oil sludge to useful products.

The detailed pyrolysis process flow for waste oil sludge recovery unfolds in a precise, step-by-step sequence:

Oil sludge dehydration: Reducing moisture content to optimize thermal efficiency, ensuring the subsequent pyrolysis reaction proceeds smoothly.

Feeding: Using hydraulic feeder or slurry pump to load oil sludge into pyrolysis reactor, minimizing manual intervention and preventing pollutant leakage.

Pyrolysis: Heating the oil sludge to a certain high temperature in an oxygen-free environment, where complex hydrocarbons break down into volatile oil gases.

Oil gas cooling: Condensing the oil gases into liquid fuel oil through a cooling system, capturing the primary recoverable resource.

Gas cleaning and recovery for heating: Purifying non-condensable syn-gas to remove impurities like sulfur, then redirecting it to the reactor’s heating system to create a self-sustaining energy cycle.

Slagging: Discharging the cooled solid residue (slag) from the reactor, ready for further utilization.

This streamlined process yields three valuable outputs: recoverable fuel oil, solid residue, and syn-gas—all of which can be sold as commodities or reused in industrial operations, maximizing both environmental and economic returns.

1. Fuel oil: we can obtain about 60% fuel oil, which can be used ad heating fuel in heavy oil machineries, such as cement plant, steel plant, metallurgical plant, glass plant, power plant etc; or be refined into low level diesel to enlarge applications.
2. Slag: we can obtain about 30% slag, which can be used as building materials to make road foundations and bricks.
3. Syn-gas: we can obtain about 10% syn-gas, which can be used to heat pyrolysis reactor as heating fuel after purifying.

In summary, Huayin oil sludge recycling pyrolysis machine can dispose of oil sludge to valuable resources. And in addition to oil sludge, our pyrolysis machine can also dispose of waste tires, plastics, rubber, MSW, etc., and can provide customized solution for you.
