Oil Sludge Treatment Processes

This review considers effective modern methods for oil sludge and acid resid treatment. We analyze in detail the technologies for dewatering, solidification, solvent extraction, thermal treatment (including in the presence of catalysts), and modern oil sludge and solid fuel (oil shales, coals) treatment methods. We note that the dominant criteria for the effectiveness of oil waste utilization technology should be cost effectiveness and reduced environmental stress.
