Oily Sludge Recovery using Microwave Pyrolysis Technique.

The oily sludge treatments catch widespread attention. But, management of sludge is difficult and costly undertaking. The oil recovery pyrolysis temperature, heating rate and carbon wt.% is discussed. The recovered aliphatic, aromatic, elemental components and gases were obtained with respect to the nitrogen flow rate. The present work showed that as the heating rate increases, both the % pyrolysis oil and gases increases up to 600°C, while the % pyrolysis char decreases. Beyond 600°C the pyrolysis gases % increases, the pyrolysis oil % decreases while the % pyrolysis char continuous decreases. Gas chromatography, and calorific value used to examine the hydrocarbon compositions of the virgin, sludge, and pyrolysis oils. [ABSTRACT FROM AUTHOR]
