  • Patent number: 8721771
    Abstract: An exhaust gas plume mitigation process and system includes either mixing secondary heat into a moisture rich exhaust gas stream, or diverting a moisture rich exhaust gas stream into a primary exhaust stack having hot exhaust gases flowing therethrough. Moisture rich exhaust gas from a liquid concentrator may be diverted into a high temperature exhaust stack of an engine, a generator, or a flare. The high temperature exhaust gases from the engine, the generator, or the flare raise the temperature of the moisture rich exhaust gas from the concentrator. The high temperature exhaust gases from the engine, the generator, or the flare are also lower in moisture content, so that the moisture rich exhaust gas from the concentrator is diluted by the drier high temperature exhaust gas. As a result, the mixed gas is less likely to develop a moisture plume upon exit to the atmosphere.

The bursting bubbles rupture into hundreds or thousands of micro-droplets. The micro-droplets are used together with the aqueous froth to coalesce with or otherwise bind with contaminants in the air stream. An optional feature is that massive particles greater than three microns in diameter are removed by inertial impaction, whereby those heavy particles collide with the walls of serpentine shaped vanes of a mist eliminator.

Gas and liquid from the contactor pass through a cooler and are then separated. A treating liquid regeneration system receives the treating liquid and flashes the liquid at low pressure to separate hydrocarbon gases, hydrocarbon liquid and treating liquid. The treating liquid is regenerated by heating and flashing off contaminant gases and is ultimately redelivered to the contactor.

  • Publication number: 20080173176
    Abstract: A fluid scrubber in the form of a submerged gas reactor includes a reaction vessel, a gas delivery lube partially disposed within the reaction vessel to deliver a gas into the reaction vessel and a scrubbing liquid inlet that provides a scrubbing liquid to the reaction vessel at a rate sufficient to maintain a controlled, constant level of fluid within the reaction vessel. A weir is disposed within the reaction vessel adjacent the gas delivery tube to form a first fluid circulation path between a first weir end and a wall of the reaction vessel and a second fluid circulation path between a second weir end and an upper end of the reaction vessel. During operation, gas introduced through the tube mixes with the scrubbing liquid and the combined gas and liquid flow at a high rate with a high degree of turbulence along the first and second, circulation paths defined around the weir, thereby promoting vigorous mixing and intimate contact between the gas and the scrubbing liquid.

  • Patent number: 7156895
    Abstract: A system for cleaning air wherein the air to be cleaned is bubbled up through an aqueous phase and an organic phase. The air is bubbled upwardly through the liquid to take advantage of the weight of the liquid to compress the gas, thereby increasing the solubility of the gas in the liquid. Because of specific gravity, the aqueous phase is generally at the bottom of at least one cylinder or container, and the organic phase is generally on top of the aqueous phase. Gases are removed either continuously or periodically to ensure that there are adequate reagents in the aqueous and organic phases, so that the reagents therein can be replaced as needed. There is no limit to the number of cylinders that can be used, depending upon the impurity and thus the amount of reagents to be used in treating the air.

  • Patent number: 7056367
    Abstract: A scrubber for exhaust gases comprises a series of nested counter-flow passages including a hot plenum having a star-shaped section. Exhaust gases from the hot plenum surge through a liquid bath and flow in a reverse direction through an inclined array of flat, overlapping, spaced mixing vanes, causing turbulence in the exhaust gases and the formation of highly dispersed tiny bubbles, which enhance the solution of gaseous pollutants into the scrubbing liquid. Mist eliminator vanes strip entrained liquids from the exhaust gases. The hot plenum, reheats the exhaust gases to an unsaturated level. The scrubber is highly effective in reducing particulate matter, stripping sulphur dioxide and nitrogen dioxide from exhaust gases, and reducing the heat signature and visual evidence thereof.
