| 20090263299 | Hazardous gas abatement system using electrical heater and water scrubber - A hazardous gas abatement system decontaminates an exit gas stream containing global warming gases using an electrical heater and a water scrubber. One or more top flow hazardous gas inlets introduce hazardous gases into a heater compartment. Air or oxygen is introduced into a separate chamber for dynamic oxidation and cooling.

Filtered exhaust gases flow upward in an exhaust chamber surrounding the heater compartment and through water spray scrubbers. A cleaning ring mounted on an eccentric rod cleans particles from the outside of the internal heater, and the inside of the external heater.

Computer-operable methods for matching a source material to an application are disclosed. Certain aspects feature a porous body comprised of ash particles, the ash particles have a particle size distribution and interparticle connectivity that creates a plurality of pores having a pore size distribution and pore connectivity, and the pore size distribution and pore connectivity are such that a first fluid may substantially penetrate the pores. | 04-05-2012 |

| 20120275976 | FLUE GAS RECIRCULATION SYSTEM - Recirculation of treated flue gas either independently or as a substitute for ambient air at specific points of ingress in a flue gas treatment system is provided to stabilize approach temperature and related parameters such as reagent consumption and pollution admission rate preventing both the accumulation of particulate matter and excessive corrosion associated with ambient air ingress. This recirculation provides a desired turbulence within remote regions of the flue gas treatment system to reduce the amount of particulate matter that may otherwise settle and accumulate in the absorber vessel or other areas of the system thereby causing particulate matter to be conveyed to the particulate removal device. | 11-01-2012 |
| 20110274600 | OZONE OXIDATION FILTRATION AND NEUTRALIZATION AIR CLEANING SYSTEM, APPARATUS & METHOD - A filtration system for the reduction of air born contaminates by way of double oxidation and filtration. The primary oxidation is from a low cost method of producing cold plasma ozone. The second oxidation and primary filtration is from a catalyst (MAZ), a manganese activated zeolite. Final filtration is accomplished by a HEPA air filter. Air is drawn or blown into a cabinet by way of fan or blower with sufficient force to overcome pressure drop created by filter media. | 11-10-2011 |

| 20120100052 | SYSTEM AND METHOD FOR PROTECTION OF SCR CATALYST AND CONTROL OF MULTIPLE EMISSIONS - The present invention relates generally to the field of emission control equipment for boilers, heaters, kilns, or other flue gas-, or combustion gas-, generating devices (e.g., those located at power plants, processing plants, etc.) and, in particular to a new and useful method and apparatus for preventing the poisoning and/or contamination of an SCR catalyst. In another embodiment, the method and apparatus of the present invention is designed to protect an SCR catalyst, while simultaneously providing emission control. | 04-26-2012 |
| 20100202945 | Method and Apparatus for the Enhanced Removal of Aerosols and Vapor Phase Contaminants from a Gas Stream - The invention provides methods and apparatuses for removing aerosols and, in some cases, vapor phase contaminants, such as mercury, from a gas stream. One method is directed to the removal of additional aerosols from a gas stream from which aerosols have previously been removed by using a screen in combination with a primary aerosol collection device. Another method is directed to the removal of both aerosols and vapor phase contaminants by using a sorbent in combination with a screen. Another method is directed to the removal of vapor phase contaminants by using a catalyst to convert the contaminant to a form that is more easily removed from the gas stream and optionally injecting a chemical to increase the rate of conversion. The invention also provides various apparatuses for use in performing the various methods of the invention. | 08-12-2010 |
| 20130017135 | GAS PURIFICATION USING PHOTOCATALYTIC VORTEX-SUSPENDED PARTICLESAANM Anderson; KraigAACI BurlingameAAST CAAACO USAAGP Anderson; Kraig Burlingame CA US - Embodiments of the technology disclosed herein include exemplary gas purifiers that use cyclonic separation and photocatalytic purification to oxidize contaminants in unpurified gas. One such gas purifier includes a vessel that defines a tapered cyclonic chamber. Unpurified gas enters the chamber and induces a gas vortex. Photocatalytic particles in the chamber become suspended in the vortex and mix with contaminants in the incoming gas. A light source activates the photocatalytic particles, which oxidize the contaminants to purify the gas. The purified gas exits via the wide of end of the chamber. Cyclonic action forces the photocatalytic particles out of the chamber's narrow end to a recycling conduit, which conveys the photocatalytic particles back into the chamber. | 01-17-2013 |

The electrically heatable honeycomb body has at least one current distribution structure to which a plurality of short, successive voltage pulses are initially applied during activation, before a constant heating voltage is applied to the current distribution structure to heat the honeycomb body. A suitable device for the catalytic conversion of exhaust gases in an exhaust system is also provided. | 06-30-2011 |
