Title: System for the removal of contaminant soil-gas vapors

Full Record
Other Related Research

Abstract

A system extracts contaminated vapors from soil or other subsurface regions by using changes in barometric pressure to operate sensitive check valves that control air entry and removal from wells in the ground. The system creates an efficient subterranean flow of air through a contaminated soil plume and causes final extraction of the contaminants from the soil to ambient air above ground without any external energy sources.

Feed gas contaminant removal in ion transport membrane systems

Patent Underwood, Richard Paul [Allentown, PA]; Makitka, III, Alexander (Hatfield, PA); Carolan, Michael Francis [Allentown, PA]

An oxygen ion transport membrane process wherein a heated oxygen-containing gas having one or more contaminants is contacted with a reactive solid material to remove the one or more contaminants. The reactive solid material is provided as a deposit on a support. The one or more contaminant compounds in the heated oxygen-containing gas react with the reactive solid material. The contaminant-depleted oxygen-containing gas is contacted with a membrane, and oxygen is transported through the membrane to provide transported oxygen.

Feed gas contaminant removal in ion transport membrane systems

Patent Carolan, Michael Francis [Allentown, PA]; Miller, Christopher Francis [Macungie, PA]

Method for gas purification comprising (a) obtaining a feed gas stream containing one or more contaminants selected from the group consisting of volatile metal oxy-hydroxides, volatile metal oxides, and volatile silicon hydroxide; (b) contacting the feed gas stream with a reactive solid material in a guard bed and reacting at least a portion of the contaminants with the reactive solid material to form a solid reaction product in the guard bed; and (c) withdrawing from the guard bed a purified gas stream.

In situ removal of contamination from soil

Patent Lindgren, Eric R [Albuquerque, NM]; Brady, Patrick V [Albuquerque, NM]

A process of remediation of cationic heavy metal contamination from soil utilizes gas phase manipulation to inhibit biodegradation of a chelating agent that is used in an electrokinesis process to remove the contamination, and further gas phase manipulation to stimulate biodegradation of the chelating agent after the contamination has been removed. The process ensures that the chelating agent is not attacked by bioorganisms in the soil prior to removal of the contamination, and that the chelating agent does not remain as a new contaminant after the process is completed.

Electrokinetic removal of charged contaminant species from soil and other media using moderately conductive adsorptive materials

Patent Lindgren, Eric R [Albuquerque, NM]; Mattson, Earl D [Idaho Falls, ID]

Method for collecting and concentrating charged species, specifically, contaminant species in a medium, preferably soil. The method utilizes electrokinesis to drive contaminant species into and through a bed adjacent to a drive electrode. The bed comprises a moderately electrically conductive adsorbent material which is porous and is infused with water or other solvent capable of conducting electrical current. The bed material, preferably activated carbon, is easily removed and disposed of. Preferably, where activated carbon is used, after contaminant species are collected and concentrated, the mixture of activated carbon and contaminant species is removed and burned to form a stable andmore » easily disposable waste product. « less

Vapor phase elemental sulfur amendment for sequestering mercury in contaminated soil

Patent Looney, Brian B.; Denham, Miles E.; Jackson, Dennis G.

The process of treating elemental mercury within the soil is provided by introducing into the soil a heated vapor phase of elemental sulfur. As the vapor phase of elemental sulfur cools, sulfur is precipitated within the soil and then reacts with any elemental mercury thereby producing a reaction product that is less hazardous than elemental mercury.
