the resource utilization of oily sludge

With increasingly strict global environmental protection regulations, the efficient treatment of oily sludge has become an important issue in the petrochemical industry. As a major oil-producing region in the world, the Middle East generates a large amount of oily sludge during the processes of oil extraction, transportation, storage and refining. The main sources include drilling mud and crude oil separation residues from oilfield exploitation, bottom sludge from storage tanks in refineries, waste residue from oil pipelines, and contaminated soil due to leakage.
