Abstract: A method for the combined reduction of sulfur dioxide, SO2, and nitrogen oxides, NOx, in the gas stream of a furnace from the combustion of fossil fuels is disclosed. In a narrow gas temperature zone in a furnace, NOx is converted to nitrogen by reaction with a reducing agent such as urea or ammonia with negligible residual ammonia and other reaction pollutants. In about this same temperature zone, SO2 will react with calcium oxide particles, derived from the calcination of lime, Ca(OH)2, or limestone, CaCO3, to form CaSO4 particles. A wide size distribution of aqueous droplets, containing dispersed lime or very fine limestone particles and dissolved urea or ammonia, is injected at the outer edge of the furnace gas zone at which the SO2 and NOx reduction reaction are effective. The key element in this invention is that the aqueous droplet size distribution is optimized for the specific furnace dimension while the concentration of the reactants, urea or ammonia and lime or very fine limestone, is optimized for optimum reaction rates. Special injectors produce the different size droplets that vaporize throughout said gas zone, thereby distributing said lime or limestone particles and urea or ammonia gas molecules exclusively throughout the combustion gas zone being treated. Also disclosed is a system to produce said aqueous mixture and effectively accomplish this injection. This method can be combined with other NOx and SO2 reduction processes to sharply reduce overall NOx and SO2 emissions from the combustion gas effluent.

Four metal plates (7,8,10,11) constituting the principal and supplementary parts (5,6) are pressed to have in them several protuberances and recesses. These metal plates are laid one on another to form in them some hollow spaces and sealed regions.

Abstract: A process is provided for treating a liquid effluent from a gas to liquid conversion reactor. A synthesis gas is initially converted to a liquid hydrocarbon phase in the gas to liquid conversion reactor. The liquid hydrocarbon phase includes a heavier liquid paraffinic wax compound and a lighter liquid paraffinic compound. The liquid hydrocarbon phase is discharged from the gas to liquid conversion reactor in a reactor effluent and an abrasive solid particle medium is entrained in the reactor effluent to form a fluidizable mixture. The reactor effluent is conveyed past a heat transfer surface which is cooler than the reactor effluent. The fluidizable mixture is contacted with the heat transfer surface and the liquid hydrocarbon phase is cooled to a temperature below the melting point of the heavier liquid paraffinic wax compound. Consequently, the heavier liquid paraffinic wax compound is converted to a plurality of unconsolidated solid wax particles. A slurry is formed from the plurality of unconsolidated solid wax particles and the remaining lighter liquid paraffinic compound.

Abstract: A method and system for the use of waste coal fines to reduce nitrogen oxides emissions from a coal-fired cyclone boiler. A coal water slurry including waste coal fines is injected as a co-firing fuel into a cyclone barrel of the cyclone boiler to partially oxidize the coal water slurry in a central portion of the cyclone barrel where injected. This produces a reducing zone having reducing gas species that convert nitrogen oxides to diatomic nitrogen. The coal water slurry can alternatively be injected into the cyclone barrel from a secondary combustion air conduit. The evaporation of the water from the coal water slurry reduces the overall combustion temperature in the cyclone barrel, further reducing the production of nitrogen oxides.

Abstract: A system and process are provided for converting a hydrocarbon gas to a reformed gas containing hydrogen and carbon monoxide. In accordance with a first embodiment, the system includes a primary combustor, compressor and power turbine. The process is practiced by compressing a feed air in the primary compressor to produce a primary air. The primary air is fed with a primary hydrocarbon gas to the primary combustor, producing a reformed gas that drives the primary power turbine. The primary power turbine is linked to the primary compressor, compressing the feed air in an energy self-sufficient manner. In a second embodiment, the system of the first embodiment further includes a secondary combustor, compressor and power turbine. The process is practiced in the same manner as the first embodiment, producing the reformed gas and driving the primary power turbine and compressor. A portion of the primary air is also fed with a secondary hydrocarbon gas to the secondary combustor, producing an off-gas that drives the secondary power turbine and compressor to compress a gas in an energy self-sufficient manner. In a third embodiment, the system is substantially the same as the second embodiment, but reconfigures the compressors and power turbines and further includes an auxiliary secondary power turbine. The process is practiced in the same manner as the first embodiment, producing the reformed gas and driving the primary power turbine and compressor. The off-gas is produced in the same manner as the second embodiment to drive the secondary power turbine, but the secondary power turbine drives an auxiliary primary compressor, compressing the feed air ahead of the primary compressor in an energy self-sufficient manner. The off-gas further drives the auxiliary secondary power turbine to provide additional power for alternate power users.
