Characterization and treatability of a contaminated soil from an oil exploration zone
Abstract: A crude contaminated soil, arising from an oil production zone in Tabasco, Mexico was studied. A sample of about 40 kg was dried and screened through meshes 10-100. Total petroleum hydrocarbons and 6 metals (Cd, Cu, Cr, Ni, V and Zn) were determined to the different portions. For soil which passed mesh 10, six non-ionic, three anionic and one zwitterionic surfactant solutions (0.5%) ...

Acute toxicity of chemically and mechanically dispersed crude oil on juvenile sea bass (Dicentrarchus labrax): Absence of synergistic effects between oil and dispersants
The goal of this experiment was to assess the relative acute toxicities of mechanically and chemically dispersed oil (Crude Arabian Light) in controlled conditions. Juvenile sea bass (Dicentrarchus labrax) were exposed to four commercial formulations of dispersants (Corexit EC9500A, Dasic Slickgone NS, Finasol OSR 52, Inipol IP 90), to mechanically dispersed oil and to the corresponding ...

Water repellency in oil contaminated sandy and clayey soils
Two sites from a humid tropical environment were studied with respect to soil water repellency caused by hydrocarbon contamination. Samples were analyzed for water repellency (molarity ethanol droplet method), total petroleum hydrocarbons, acute toxicity (Microtox) and field capacity. At both sites, water absorption times were logarithmically related to the molarity ethanol drop value (R > ...

On-Site TPH in Soil Measurements
On-site analysis of total petroleum hydrocarbon (TPH) concentration levels in soil are easily handled using the InfraCal TOG/TPH Analyzers manufactured by Wilks Enterprise, Inc. The InfraCal TOG/TPH Analyzers are portable infrared (IR) analyzers that quickly determine TPH levels in less than 10-15 minutes, including the extraction. Concentrations as low as 10 ppm to well over 10,000 - 20,000 ...

Cleanup levels at an oil distribution and storage station in eastern central Mexico determined from a health risk assessment
The subsoil of an oil storage and distribution station located in eastern central Mexico was characterised in terms of some fuel fractions and metals. The site was found to be contaminated mainly with total petroleum hydrocarbons (TPHs) at a concentration higher than that legislated in Mexico. The presence of BTEX (benzene, toluene, ethylbenzene and xylenes) and 11 of the 16 USEPA polynuclear ...

Eco-toxicity of oily wastes containing TENORM
Oily wastes are considered as one of the most hazardous waste types. Additionally to petroleum components, they can contain radioactive elements. This study aimed to estimate the toxicity of four raw and two treated waste samples obtained from petroleum production yard. Eight elutriate bioassays using plants ( Raphanus sativus and algae Scenedesmus quadricauda ), crustacean ( Daphnia magna ...

Electrocoagulation and nanofiltration integrated process application in purification of bilge water using response surface methodology
Marine pollution has been considered an increasing problem because of the increase in sea transportation day by day. Therefore, a large volume of bilge water which contains petroleum, oil and hydrocarbons in high concentrations is generated from all types of ships. In this study, treatment of bilge water by electrocoagulation/electroflotation and nanofiltration integrated process is ...

U.S. Air Force DOD Project - Case Study
Environmental Issues Controlling the off-gas from a remediation project, where high concentrations of petroleum hydrocarbons are present, can be a difficult if not dangerous process when utilizing internal combustion engines and conventional oxidation technology. In more recent years, the use of high vacuum pumps to accomplish both liquid and gas phase extraction — sometimes referred to ...

Monitoring fuels in Stormwater - Case study
The Situation A major pipeline company has large storage tank farms throughout the Western States. The pipeline company transports, stores, blends additives, and distributes gasoline, diesel, and jet fuel to retail service stations and airports. Due to the quantity and movement of fuel at these facilities, there is always the potential for fuel spills. These facilities prevent out of compliance ...

Monitoring leaks in Heat exchangers - Case study
The Situation A California refinery produces xylene for use as commercial product and a precursor for petrochemical manufacturing. A primary component to the production of xylene is the isolation and purification of the chemical from a complex mixture of petroleum hydrocarbons. Steam based heat exchangers are used to process the xylene. Inherent to the design and rough duty heat exchangers face ...
