Abstract: Exemplary embodiments are directed to a diffuser assembly configured to be disposed in an extraction path of an extracting solvent in an extraction vessel. The diffuser assembly includes a housing configured to be disposed within the extraction vessel, the housing including an inner surface and an outer surface. The diffuser assembly includes an inlet structure disposed within the housing. The diffuser assembly includes an outlet structure disposed within the housing and spaced from the inlet structure to form a mixing chamber between the inlet structure and the outlet structure. The inlet structure and the outlet structure each have a porosity configured for passage of the extracting solvent therethrough. Passage of the extracting solvent through the inlet structure, the mixing chamber, and the outlet structure redistributes flow of the extracting solvent along the extraction path.

Abstract: The invention provides methods for the measurement of carbon dioxide leakage from sequestration reservoirs. Tracer moieties are injected along with carbon dioxide into geological formations. Leakage is monitored by gas chromatographic analyses of absorbents. The invention also provides a process for the early leak detection of possible carbon dioxide leakage from sequestration reservoirs by measuring methane (CH4), ethane (C2H6), propane (C3H8), and/or radon (Rn) leakage rates from the reservoirs. The invention further provides a method for branding sequestered carbon dioxide using perfluorcarbon tracers (PFTs) to show ownership.
