  • Remediation of Oil Refinery Sludge Basin

    Abstract Work was completed in early 1992 to clean up a 5.5 acre (2.2 ha) stormwater sludge basin for an oil refinery company. The basin, which had served as a stormwater collection and settling pond for over 40 years, contained oily sludges with high concentrations of certain metals and volatile organic compounds. The closure plan included a combination cement-bentonite slurry wall and jet ...

  • Refinery remediation: fuel recovery and recycling

    Introduction The site is a former refinery that occupied approximately 64 acres of land in West Texas. Refinery operations produced all grades of gasoline, tractor fuels, diesel, distillate products, and fuel oils and operated between 1939 and 1954. As a result of past waste management practices, releases to soils and ultimately ground water occurred, resulting in the formation of a ...

  • Polycyclic aromatic hydrocarbons in Niger Delta soil: contamination sources and profiles

    Abstract The distribution and sources of PAHs in soil as well as PAHs profiles have been investigated in areas with anthropogenic pollution in the Niger Delta (Nigeria) such as Warri and Ughelli. PAHs were identified in 21 soil samples (0- 10cm upper layer) collected in May, 2003. The typical total PAHs level in Niger Delta soil ranged from 182 ± 112 – to - 433 ±256 ìg/kg dw. PAH ...

  • Stability and environmental geochemical profile of toxic heavy metals in soils around a crude oil refinery

    Soil samples were taken near oil refinery activities, bulk and fractionated heavy metal contents, as well as other physico-chemical characteristics were measured. The reported results indicate that the enrichment factors of the measured heavy metals were 3.9, 1.8, 1.3, 23.7 and 52.5 for lead, nickel, zinc, cadmium and mercury, respectively. The samples can be considered to be extremely ...

  • Slurry Phase Biological Treatment

    Slurry phase biological treatment involves the controlled treatment of excavated soil in a bioreactor. The excavated soil is first processed to physically separate stones and rubble. The soil is then mixed with water to a predetermined concentration dependent upon the concentration of the contaminants, the rate of biodegradation, and the physical nature of the soils. Some processes pre-wash the ...

  • Biodegradation of total petroleum hydrocarbon (TPH) in Jordanian petroleum sludge

    Bioremediation, or the use of micro-organisms to decontaminate soil or groundwater, is being increasingly seen as an effective, environment-friendly treatment for oil-contaminated sites. In this study, the results are presented concerning a laboratory screening of several natural bacterial consortia and laboratory tests to establish the performance in degradation of hydrocarbons contained in oily ...

  • LNAPL remediation using electrical resistance heating

    Abstract An Electrical Resistance Heating (ERH) pilot test was conducted in the fall of 1998 to determine the effectiveness of using ERH in combination with soil vapor extraction (SVE) for the remediation of benzene and light nonaqueous-phase liquids (LNAPL) at an island location on a river in the Midwest. Hydrocarbon-stained soils were discovered on an island in Ohio in May 1993 during the ...
