BACKGROUND Due to the high concentrations of total petroleum hydrocarbons (TPH) in oily sludge and their environmental hazards, the concern regarding their effects on health and the environment has increased. The main objective of this research was focused on evaluating the feasibility of using Fenton process in removing TPH in oily sludge from Shiraz oil refinery, Southern Iran. RESULTS To d...

Spent residuum hydroprocessing (RHDP) catalysts are hazardous waste bearing high-content vanadium and large amounts of oily pollutants. In this paper, a process featuring Fenton-like reaction alkaline leaching was proposed to recover from spent RHDP catalysts. the first step, using peroxide conducted degrade pollutants make surface catalyst becomes hydrophilic. second vanadium-containing deposi...

In the event of a marine oil spill and its subsequent response operations, different types oily wastes are generated in large quantities, their management is significant challenge that responders face. The goal this study to develop comprehensive pattern recognition modeling framework for deriving grouping set unique clusters separate from each other. main idea group based on characteristics, s...

Field and laboratory investigations were conducted to characterize the composition of petroleum hydrocarbons in oily sludge underlying contaminated soils a decommissioned oilfield waste pit Kuwait. The results show that hydrocarbon was spatially variable. Highly toxic species such as BTEX PAHs generally lacking, both sludge- soil-borne dominated by long-chain hydrocarbons. soil contamination de...

The understanding of waste generation is critical importance for effective oily management in marine oil spill response operation. A system dynamics model was developed this study to estimate the quantity generated from operations. Various aspects were considered, including weather conditions, spilled volume and characteristics, time, methods. types include recovered oil, water, sorbents, perso...

SummaryWhile the Inuit diet was highly cardio-protective and consuming oily fish within a Western diet is to a lesser degree, the case for purified fish oil supplements is less convincing. Purification of fish oil removes lipophilic polyphenols which likely contribute to the health benefits of oily fish; leaving the ω3 highly unsaturated fatty acids exposed and prone to conferring oxidative and...

Oily wastewaters from oil refineries and oil distribution centers are one of the most important environmental concerns in recent decades; therefore, it is critical to treat these types of wastewaters. In this study, the performance of different polyethersulfone hollow fiber membranes in oily wastewaters treatment was investigated and the effects of operating conditions such as transmembrane pre...
