Abstract

In situ hydrous pyrolysis/partial oxidation of organics at the site of the organics constrained in an subsurface reservoir produces surfactants that can form an oil/water emulsion that is effectively removed from an underground formation. The removal of the oil/water emulsions is particularly useful in several applications, e.g., soil contaminant remediation and enhanced oil recovery operations. A portion of the constrained organics react in heated reservoir water with injected steam containing dissolved oxygen gas at ambient reservoir conditions to produce such surfactants.

Method and apparatus for destroying organic contaminants in aqueous liquids

Patent Donaldson, Terrence L [Lenior City, TN]; Wilson, James H [Oak Ridge, TN]

A method and apparatus for destroying organic contaminants, such as trichloroethylene, in aqueous liquids, such as groundwater, utilizing steam stripping integrated with biodegradation. The contaminated aqueous liquid is fed into a steam stripper causing the volatilization of essentially all of the organic contaminants and a portion of the aqueous liquid. The majority of the aqueous liquid is discharged from the steam stripper. The volatilized vapors are then condensed to the liquid phase and introduced into a bioreactor. The bioreactor contains methanotrophic microorganisms which convert the organic contaminants into mainly carbon dioxide. The effluent from the bioreactor is then recycled backmore »« less

In situ thermally enhanced biodegradation of petroleum fuel hydrocarbons and halogenated organic solvents

Patent Taylor, Robert T [Livermore, CA]; Jackson, Kenneth J [San Leandro, CA]; Duba, Alfred G [Livermore, CA]; ...

An in situ thermally enhanced microbial remediation strategy and a method for the biodegradation of toxic petroleum fuel hydrocarbon and halogenated organic solvent contaminants. The method utilizes nonpathogenic, thermophilic bacteria for the thermal biodegradation of toxic and carcinogenic contaminants, such as benzene, toluene, ethylbenzene and xylenes, from fuel leaks and the chlorinated ethenes, such as trichloroethylene, chlorinated ethanes, such as 1,1,1-trichloroethane, and chlorinated methanes, such as chloroform, from past solvent cleaning practices. The method relies on and takes advantage of the pre-existing heated conditions and the array of delivery/recovery wells that are created and in place following primary subsurface contaminantmore »« less

Subterranean drilling and in situ treatment of wastes using a contamination control system and methods relating thereto

Patent Jessmore, James J.; Loomis, Guy G.; Pettet, Mark C.; ...

Systems and methods relating to subterranean drilling while maintaining containment of any contaminants released during the drilling. A thrust block installed over a zone of interest provides an overflow space for retaining any contaminants and excess sealant returns. Negative air pressure may be maintained in the overflow space by a ventilation system. Access ports in the thrust block seal the overflow space from the surrounding environment with a membrane seal. A flexible sack seal in the access port may be connected to a drill shroud prior to drilling, providing containment during drilling after the drill bit penetrates the membrane seal.more »« less

Method and apparatus for spatial compression and increased mobility resolution of ions

Patent Ibrahim, Yehia M.; Garimella, Sandilya; Smith, Richard D.

Methods and apparatuses for ion peak compression and increasing resolution of ions are disclosed. Packets of ions are introduced into a device. A first electric field is applied for dispersing the ion packets temporally or spatially according to their mobilities. A second intermittent traveling wave is applied for regrouping or merging the dispersed ion packets into a lesser number of trapping regions with narrower peaks. The ions packets are compressed into the narrower peak regions by varying a duty cycle of the intermittent traveling wave.
