20080292512 | METHOD FOR PRODUCING AND USING A CARBONACEOUS SORBENT FOR MERCURY REMOVAL - A method for removing mercury from flue gas comprises: applying a precursor of a sticky substance to surfaces of carbonaceous sorbent particles; injecting the carbonaceous sorbent particles into contact with flue gas, wherein the carbonaceous sorbent particles adsorb mercury from the flue gas and at least one of a temperature of the flue gas and a component of the flue gas changes the precursor into the sticky substance that increases the stickiness of the carbonaceous sorbent particles; and removing the carbonaceous sorbent particles having mercury adsorbed thereon from the flue gas. In one embodiment, the precursor is ammonia or an ammonia compound and the sticky substance is ammonium sulfate. The method may further comprise applying bromine or a bromine compound to the carbonaceous sorbent particles. | 11-27-2008 |
20080305017 | Gas Quench and Scrubber Draw-Off System - A gas desulfurization scrubbing system for removing sulfur oxides from gases, such as those of fossil fuel burning operations or other manufacturing process emitting sulfur oxides, and for collecting reaction products of the desulfurization chemical reactions. A quenching section is disposed in a gas duct upstream of a gas desulfurization scrubbing tower and a scrubbing slurry is provided at that section for quenching and chemically reacting with the gas. A quench reaction product is collected, at a location between the quenching section and the scrubbing tower, for use in making commercial by-products, such as gypsum. | 12-11-2008 |
20080311010 | Atomization of Fluids By Mutual Impingement of Fluid Streams - The present invention relates to the field of atomizing one or more fluids.

20090010816 | APPARATUS AND METHOD FOR CONTROLLED COMBUSTION OF GASEOUS POLLUTANTS - The present invention relates to systems and methods for controlled combustion of gaseous pollutants while reducing and removing deposition of unwanted reaction products from within the treatment systems. The systems employ a two-stage thermal reactor having an upper thermal reactor including at least one inlet for mixing a gaseous waste stream with oxidants and combustible fuels for thermal combustion within the upper thermal reactor. The upper thermal reactor further includes a double wall structure having an outer exterior wall and an interior porous wall that defines an interior space for holding a fluid and ejecting same, in a pulsating mode, through the interior porous wall into the upper thermal reactor to reduce deposition of the reaction products on the interior of the upper reactor chamber. The two-stage thermal reactor further includes a lower reactor chamber for flowing reaction products formed in the upper thermal reactor through a water vortex that provides a water overflow along the interior of the lower reactor chamber thereby reducing deposition of unwanted products on the interior surface of the lower reactor. | 01-08-2009 |
