“…Since the existence of problems of the secondary pollution [7,8] and the high viscosity of fuels [9], the application of incinerating oil sludge directly is limited. With its characteristics to crack high molecular weight organic compounds into lower ones, and to separate the stable emulsion of oil sludge into oil, water, and residue fraction efficiently, pyrolysis treatment were used widely in the field of oily waste disposal.…”

In this study, pyrolysis experiments of two kinds of oil sludge were conducted using a bench-scale fixed bed reactor, which is mainly consisted of a pyrolyzer and a reformer reactor. The effects of the pyrolysis method and the catalysts on the yield and quality of oil products obtained from pyrolysis of oil sludge were investigated. Characterization of the oil products was preliminary judged by comparing their distillation results with the diesel standard and the oil product without catalyst usage. Then, the chemical characterization of a part of the pyrolytic oil was conducted by FT-IR and NMR analysis. In the last step of these experiments, the oil products obtained from pyrolysis of oil sludge with the use of oil field sludge ash and oil tank sludge ash as catalysts were mixed with diesel oil by the volume ratio of one-to-five and one-to-ten. The fuel characteristic of the oil mixtures was identified from the point of the viscosity, the density, the cetane index, the carbon number distribution and the higher heating value (HHV). The results of experiment show that the highest oil product yield was obtained at the one-stage pyrolysis of the oil field sludge and also the oil tank sludge with the oil field sludge ash as the catalyst. According to the results of NMR analysis, the main part of the carbon in the oil product from pyrolysis of the oil sludge with the oil sludge ash was aliphatic carbon. The total ring number of oil products decreased owing to the hydrogenation and ring-open of naphthenic hydrocarbon during the catalytic pyrolysis process. The highest HHV and the cetane index could be obtained when the oil product from the one-stage pyrolysis process of the oil field sludge with the oil field sludge ash was mixed with diesel by the mixing ratio of 1: 10. The results of this study are of practical interest and will help to lead the researchers to more thinking about the oil recovery from oil sludge.

STUDY OF THE THERMAL DECOMPOSITION OF PETROCHEMICAL SLUDGE IN A PILOT PLANT REACTOR ABSTRACTThe pyrolysis of a sludge produced in the waste water treatment plant of an oil refinery was studied in a pilot plant reactor provided with a system for condensation of semivolatile matter. The study comprises experiments at 350, 400, 470 and 530 ºC in nitrogen atmosphere. Analysis of all the products obtained (gases, liquids and chars) are presented, with a thermogravimetric study of the char produced and analysis of main components of the liquid. In the temperature range studied, the composition of the gas fraction does not appreciably vary. In the liquids, the light hidrocarbon yield increases with increasing temperature, whereas the aromatic compounds diminish. The decomposition of the solid fraction has been analysed, finding a material that reacts rapidly with oxygen regardless of the conditions it is formed.

Recovery of Petroleum Hydrocarbons from Oily Sludge Landfilled Soil

Three types of experiments, based on the physical properties of oily sludge landfilled soil, were conducted to recover total petroleum hydrocarbons (TPH) from the soil. These experiments included gravity separation, solvent extraction using water, and air floatation. The oil portion was not easily separated from the wet (raw) soil because water molecules aggregate the soil particles, despite the fact that the soil was sandy. However, the drying and grinding processes destroyed the aggregates, causing the TPH recovery to increase to approximately 60% when air floatation was used. The drying process decreased the specific gravity of the soil sample, thereby enhancing the overall recovery of TPH from the soil. Although thermal desorption and/or incineration are common choices for heavily dumped sites, physical separation can recover the oil portion instead of simply removing it.
