Abstract

A method for treating an environmental medium having organic contaminants is disclosed. A mixture is added to the environmental medium. The environmental medium is heated to activate the mixture and to evaporate the organic contaminants within the environmental medium to generate contaminated vapors. The mixture acts as an additional heat source. The mixture includes a metal powder. The contaminated vapors are extracted via a perforated pipe, thereby removing the organic contaminants in a gaseous form from the environmental medium. The organic contaminants have an initial boiling point in range of 50° C. to 400° C., when immersed in water or in contact with moist soil, measured at a standard atmospheric pressure of 1 atm.

Abstract

A method for treating an environmental medium is disclosed. A heat source with a heat exchanger is provided aboveground in proximity to the environmental medium to be treated. A mixture is heated to a temperature below a boiling point of the mixture. The mixture consists of a vegetable oil, an emulsifier, and water. The heated mixture and an alkaline compound catalyst are introduced into the contaminated environmental medium. The alkaline compound is potassium hydroxide or sodium hydroxide. The alkaline compound is dissolved in an alcohol in an amount ranging from 0.1 to 5% of the alkaline compound to form an alkyl oxide solution.

Abstract

A method and a system for in-situ remediation of recalcitrant organic and inorganic contaminants in an environmental medium are disclosed. Dissolved gases from water and an oil are removed to form degassed water and a degassed oil. The degassed water and the degassed oil are mixed to form a surfactant-free oil-in water emulsion. The surfactant-free oil-in-water emulsion is injected into the environmental medium, thereby producing anaerobic conditions to cause indigenous anerobic bacteria to biodegrade residual concentrations of the contaminants in the environmental medium.

Abstract

The present subject matter relates to a composition for in-situ remediation of soil and aquifer comprising of a water miscible oil; a solvent (for dissolving the vegetable oil to form a solution); and a catalyst (selected from enzymes biocatalysts, particularly lipases, alkaline compounds, heat or combinations thereof). The present subject matter provides a process for the preparation of the composition and application of the same for surface remediation. Further, the present subject matter provides an in-situ alcoholysis remediation method to reduce contaminant concentrations in aquifer and soil by enabling the generation of both soluble and slowly fermenting electron donors required for the anaerobic remediation of organohalide compounds contaminating soils and groundwater. The method of remediation includes mixing an engineered water-soluble oil or water miscible oil with a solvent and adding a catalyst to groundwater to promote the formation of fatty acid alkyl esters, carboxylic acid salts and glycerol.

Abstract

A formulation for the bioremediation of soil or groundwater includes from about 80 to 95% of an emulsifiable C4-C22 vegetable oil selected from the group consisting of soybean oil, coconut oil, rapeseed (canola) oil, peanut oil, crambe oil, sunflower oil and combinations thereof; and from about 5 to 20% of an emulsifier selected from the group consisting of a vegetable oil derived from a C16-C20 fatty acid ester or a mixture of such esters. The efficacy of the formulation is improved by adding hydrogen-enriched water to the emulsifiable oil as a dilution fluid.
