Sihai - Oil Sludge Treatment Pyrolysis Plant
Oil sludge is a complex physico-chemical mixture, consisting of three distinct fractions: water, oil and solid (metals, salts, sand, etc.).
As most promising of the presented methods of utilization of oil sludge is pyrolysis, it can refine oil sludge by thermal cracking process which compared with the other methods have a number of significant advantages.
Oil sludge (OS) is a common waste in oil field mining, oil transportation, fining, storage and other oil related process which consisting of three distinct fractions: water, oil and solid (metals, salts, sand, etc.). OS can cause great damage to the environment and threaten human`s health if not treated properly.
During the drilling process, the oil-containing silt,which brought from replacing the well-drilling and extracting the drive pipe, will be left around the well site. The oil-containing silt that is covered with various sands and sundries, etc., will be piled up more and more before the site is cleaned up or the oily sludge is temporarily piled up for a period of time. The oily sludge comes from the deep drilling strata, and contains a large number of benzene series, phenols, anthracene, pyrene and other odorous toxic substances. It will not only damage the soil or pollute the environment, but also cause the waste of resources if not treated well.
Oil sludge treatment plant is designed to convert oil sludge into valuable pyrolysis oil, sand, and combustible gas, offering a sustainable and profitable solution for waste management.
Modular Design
Compact and Portable: Our pyrolysis plants feature a modular design for easy transportation and rapid installation, with flexible production scalability.

User-Friendly Interface
Advanced Control Systems: Featuring program control, safety interlocking, and a user-friendly interface for real-time monitoring, alarm, automatic data collection, and wireless remote transmission.
- Load oil sludge into the reactor by hydraulic feeder, then seal the door after loading is finished.
- Start the machine and the reactor will be rotating and heated by fuel. When the temperature reaches the degree of 250 to 280, the oil steam will be continuous produced until the temperature reaches 350-480 C. Oil steam will flow through oil gas separator, light component will enter the condensers and liquified as fuel oil, meanwhile the heavy oil will be discharged automatically into in heavy oil tank.
- The liquefied part will be condensed as fuel oil, and the part which cannot be liquefied will be transferred by the water seal back to the burning chamber to be reused as heating material.
- The exhaust gas generated during heating the reactor will be purified and cooled down in 2 scrubbers(1 water pond type scrubber and 1 water spray, ceramic ring adsorption and activated carbon absorption type scrubber ). Finally, it will be discharged environmental friendly.
