Paper Title
Characterization of Oily Sludge using Microwave Pyrolysis Technique

Abstract
Sludge is the most significant wastes generated from the petroleum industry. It is a complex emulsion of various petroleum hydrocarbons (PHCs), water, metals, and fine solids. Due to its increased generation quantities and hazardous nature around the world, the effective treatment of oily sludge has attracted widespread attention. The complexity of its composition and diversity of its origin sources makes its management difficult and costly undertaking. The effects of temperature, heating rate and carbon wt.% upon oil recovery pyrolysis oil percentages carried out and investigated. The effect of nitrogen flow rate on the recovered aliphatic, aromatic, elemental components and gases obtained. The results showed that 600OC is the ideal temperature for recovering sludge oil pyrolysis based on the highest valuable compounds in the liquid product and lower heating energy requirements at this temperature. The virgin, the sludge, and the pyrolysis oils examined for hydrocarbon composition by gas chromatography coupled with a mass selective spectrometry detector and a flame ionization detector.
