Acid Sludge Recycling Process in Oil Refining Industry and Convert It to Bitumen

Thousands ton of acidic sludge is produced daily as by product in the used motor oil refining industries. The acidic sludge contains unsaturated compounds which are non-polar and asphaltene. The objective of this study was performance improvement of acidic sludge by using additives (kaolin, Styrene Butadiene Styrene (SBS), Calcium carbonate hydrate) so that recovery to bitumen.SBS is one of the elastomer thermoplastic kaolin due to the chemical structure as filler, stabilizer and agent concentration and calcium carbonate is used to decreasing acidity rate of acidic sludge and promoting the role of the kaolin stability in bitumen was mixed with acidic sludge of industry and their effect on the acidic sludge was investigated.environmental and health hazards of acidic sludge will be decrease by treatment and neutralization. Also obtained products can be used in building and road constructions according to its specific bitumen criteria and characteristics.
