remediation of petroleum contaminated soils in urban area using thermal desorption
introduction growing use of hydrocarbon constituents in various industries have generated significant quantities of hazardous wastes which lead to environmental pollution. in recent years, the strong global demands for fossil fuels and industrial chemicals have resulted in the release of some of these compounds into soil, water and air.hydrocarbon-contaminated soils are among the important envi...
متن کاملThermal Remediation of Tar-Contaminated Soil and Oil-Contaminated Gravel
Pilot plant studies were carried out to evaluate the feasibility of remediation of coal tarcontaminated soil and oil-contaminated gravel by incineration with environmentally acceptable performance. In addition to adequate decontamination and emission control, effort was devoted to treating the special feedstocks with difficult handling properties by use of conventional combustion and feeding sy...
متن کاملRemediation of saturated soil contaminated with petroleum products using air sparging with thermal enhancement.
Pollutants in the form of non-aqueous phase liquids (NAPLs), such as petroleum products, pose a serious threat to the soil and groundwater. A mathematical model was derived to study the unsteady pollutant concentrations through water saturated contaminated soil under air sparging conditions for different NAPLs and soil properties. The comparison between the numerical model results and the publi...
متن کاملRemediation of metal-contaminated soil and sludge using biosurfactant technology.
Development of environmentally benign approaches to remediation of metal-contaminated soils and sewage sludges are needed to replace currently used techniques of either landfilling or metal extraction using caustic or toxic agents. We report results from four application technologies that use a metal-chelating biosurfactant, rhamnolipid, for removal of metals or metal-associated toxicity from m...
متن کاملMicrowave thermal remediation of crude oil contaminated soil enhanced by carbon fiber.
Thermal remediation of the soil contaminated with crude oil using microwave heating enhanced by carbon fiber (CF) was explored. The contaminated soil was treated with 2.45 GHz microwave, and CF was added to improve the conversion of microwave energy into thermal energy to heat the soil. During microwave heating, the oil contaminant was removed from the soil matrix and recovered by a condensatio...
