Abrégé

The invention generally relates to a system and method for selectively removing metals from a metal containing substance, and more particularly to a method and system for selectively extracting metals from fly ash with one or more of an acidic extraction process, basic extraction process, and supercritical carbon dioxide (scC02) and a co-solvent extraction process. Moreover, bi-products from an industrial process, e.g., coal fired plant, may be utilized in the extraction processes.

• C01F 17/00 - Composés des métaux des terres rares

Abrégé

The invention relates to a gas liquid contactor and effluent cleaning system and method and more particularly to an array of nozzles configured to produce uniformly spaced flat liquid jets shaped to minimize disruption from a gas. An embodiment of the invention is directed towards a gas liquid contactor module including a liquid inlet and outlet and a gas inlet and outlet. An array of nozzles is in communication with the liquid inlet and the gas inlet. The array of nozzles is configured to produce uniformly spaced flat liquid jets shaped to minimize disruption from a gas flow and maximize gas flow and liquid flow interactions while rapidly replenishing the liquid.

Abrégé

The invention generally relates to a method for sequestration contaminates. More particularly, the invention relates to a significant performance enhancement over existing mineral carbonation processes through the use of a high mass transfer system and an efficient pH swing reaction. More particularly, aspects of the invention are directed to direct and indirect methods of sequestering contaminates.

• B01D 53/18 - Unités d'absorptionDistributeurs de liquides

Abrégé

The invention relates to a gas liquid contactor and effluent cleaning system and method and more particularly to an array of nozzles configured to produce uniformly spaced flat liquid jets with reduced linear stability. An embodiment of the invention is directed towards a stability unit used with nozzles of a gas liquid contactor and/or an enhancer for stable jet formation, and more particularly to reducing the stability of liquid jets formed from nozzles of the gas liquid contactor. Another aspect of the invention relates to operating the apparatus at a condition that reduces the stability of liquid jets, e.g., a droplet generator apparatus. Yet another aspect of the invention relates to operation of the apparatus with an aqueous slurry. Still another aspect of the invention is directed towards to an apparatus for substantially separating at least two fluids.

Abrégé

The invention relates to a gas liquid contactor and effluent cleaning system and method and more particularly to individually fed nozzle banks including an array of nozzles configured to produce uniformly spaced flat liquid jets shaped to minimize disruption from a gas. An embodiment of the invention is directed towards a gas liquid contactor having a plurality of modules including a liquid inlet and outlet and a gas inlet and outlet. An array of nozzles is in communication with the liquid inlet and the gas inlet. The array of nozzles is configured to produce uniformly spaced flat liquid jets shaped to minimize disruption from a gas flow and maximize gas flow and liquid flow interactions while rapidly replenishing the liquid.
