Technology and Application of Oil Sludge Pyrolysis in Rotary Furnace

Abstract:

Article Preview

Technology of pyrolysis rotary furnace for oil sludge was conducted in this paper, which feature with natural gas as fuel, multi-combuster for heating controlling and novel dynamic-static sealing structure at both ends of the rotary furnace. A complete set of technical process was designed and operated with processing scale of 10 tons/day of oil sludge (The sludge moisture content is 80%). The result indicates that the system meets the standard of safe running. Recovery rate of the oil in sludge is more than 80%, while the oil content of pyrolytic residues is less than 0.3%. The main components of non-condensable gas include methane and hydrogen, occupying 35% and 40% respectively. There are high content of lightweight fractions in pyrolysis oil, such as gasoline, kerosene and diesel oil, in which the C10-C15 is near to 50%-60% and aromatics can be up to 60%. Finally, due to the high contents of carbon and aluminum salt in residue, it is much worth for the carbon and aluminum salt recovery.
