United States Patent 5,039,415 – Aug. 13, 1991
Decontamination of hydrocarbon contaminated soil
Inventors
Colasito; Dominic J. Robinson; Mery C. Smith; Alvin J.
Appl. No.: 512,474 Filed: Apr. 23, 1990
Abstract
The method of treating hydrocarbon contaminated soil that includes forming the soil into a flowing particulate stream; forming an aqueous liquid mixture of water and treating substance that reacts with hydrocarbon to form CO(2) and water; dispersing the liquid mixture into the particulate soil stream to wet the particulate; allowing the substance to react with the wetted soil particulate to thereby form CO(2) and water, whereby the resultant soil is beneficially treated.

(In situ)
Inventors
Colasito; Dominic J. Robinson; Mery C. Smith; Alvin J.
Appl. No.: 519,827 Filed: May 7, 1990
Abstract
A method of controlling hydrocarbon contamination at a zone of contaminant concentration that includes determining the locus of contamination; and dispersing into the locus a substance that reacts with the hydrocarbon to produce CO (2) and water to thereby decontaminate the locus; the dispersing including concentrating the substance in a porous zone, and forcing fluid under pressure into and through that zone to entrain and carry the substance to the contamination locus.
