Research on Treatment of Oily Sludge from the Tank Bottom by Ball Milling Combined with Ozone-Catalyzed Oxidation.
TL;DR: The combined process with “ball milling + ozone-catalyzed oxidation” as the core can solve the two problems in the treatment of oily sludge from the tank bottom by hot water-based extraction and provides a reference for the harmless and resourceful treatment of Oil–solid phase and high fine content of the recovered oil.

Facile Fabrication of Super-wettable Mesh Membrane using Locally-Synthesized Cobalt Oxide Nanoparticles and Their Application in Efficient Gravity Driven Oil/Water Separation
TL;DR: A functional cobalt (II, III) oxide (Co3O4) nanoparticle coated stainless steel mesh membrane for the application of oil-water separation was fabricated by facile spray coating, where the coating material was locally synthesized by co-precipitation method as mentioned in this paper .
Journal ArticleDOI
Optimization of influential parameters of hydrocarbon recovery from waste oily sludge by solvent extraction using solvent blend.
TL;DR: A response surface methodology was used to optimize the conditions required to recover hydrocarbons from oily sludge and combination of MEK and xylene as solvent blend demonstrated significant effect on hydrocarbon recovery in 6 to 1 and higher ratios.

Fuel recovery from waste oily sludge using solvent extraction
Essam Al Zubaidy,Dana Abouelnasr +1 more
TL;DR: In this paper, solvent extraction was used to recover oil from waste sludge generated from the storage of crude petroleum, and the recovered oil was distilled to provide diesel fuel, which contained high levels of sulfur and carbon residue, as well as a high diesel index.
Journal ArticleDOI
Accelerated biodegradation of petroleum hydrocarbon waste
TL;DR: An accelerated process has now been developed which can be completed in 10–12 days and up to 99% of total petroleum hydrocarbons are degraded and the sludges are converted from hazardous to non-hazardous according to the United States EPA's toxicity characteristic leachate procedure criteria.
Journal ArticleDOI
A study on recovery of oil from sludge containing oil using froth flotation.
TL;DR: It showed that the process followed first-order kinetics, and within the range of operating conditions studied herein, the maximum oil recovery obtained was about 55%.
Journal ArticleDOI
A combination of solvent extraction and freeze thaw for oil recovery from petroleum refinery wastewater treatment pond sludge.
TL;DR: The combination of solvent extraction with freeze/thaw is effective for high-moisture oily hazardous waste treatment and the solid residue after oil recovery had a significantly decreased TPH content, indicating that this residue may require proper management.

Petroleum hydrocarbon contamination in boreal forest soils: a mycorrhizal ecosystems perspective
TL;DR: The central premise is that mycorrhizal systems, the ubiquitous root symbiotic fungi and associated food‐web communities, occupy the structural and functional interface between decomposition and primary production in northern forest ecosystems, and are an appropriate focal point for a synthesis of PHCs in boreal forest soils.
