Abstract: An improved flue gas scrubbing apparatus and method are disclosed. The flue gas scrubber comprises a double-pipe or a two-pipe system whereby flue gas enters the system. Scrubbing is accomplished by interaction between the flue gas and base in a pre-injection zone, followed by further reaction in a primary injection zone and passage through a cyclone unit. In preferred embodiments of the invention, it comprises a bypass system by which flue gas is automatically exhausted directly to the atmosphere in case of a system failure. The gas exhausted from the apparatus following scrubbing meets or exceeds international emissions standards.

Abstract: A system and methods for separating liquids, aerosols, and solids from a flowing gas stream whereby gas flows through a helical path formed in a separator element. Partially separated gas exits the bottom of the separator element at a generally conical cavity. Clean gas exits through an inner tube that is axially aligned beneath the helical path. Separated materials exit through an annular space between the inner tube and an outer tube. Separation occurs in the helical channels which include radially diverging walls to provide an aerodynamically efficient flow, in a region of high swirl created in a generally conical cavity beneath the separator element, and in a toroidal vortex ring created in the annular space. The area and geometry of the helical path, the conical cavity, and the inner and outer tubes is optimized to provide efficient separation at varying gas flow rates and at varying liquid loads.

Abstract: Condensable vapors such as carbon dioxide are separated from light gases in a process stream. The systems and methods employ a direct exchange heat exchanger to desublimate the condensable vapors from the process stream. The condensable vapors are condensed by directly contacting a heat exchange liquid in the direct contact heat exchanger while the uncondensed light gases from the process stream form a separated light-gas stream. The separated light-gas stream can be used in a recuperative heat exchanger to cool the process stream.

Abstract: An air purification device is provided. In one embodiment, the device is comprised of stainless steel. An ambient air stream is introduced into one end of the device by low-pressure vacuum. After the air stream is introduced, a liquid mist is applied to the air stream. One embodiment employs a series of chambers for moisturizing the air stream with liquid mist, to entrain airborne impurities within moisture droplets. In some embodiments, the moisturized air stream then enters one or more collection chambers, where it undergoes cycles of slower air speed movement and higher air speed movement within one or more cyclonic separators located within one or more collection chambers. The air movement within the one or more cyclonic separators assists in separating the heavier impurity-entrained moisture droplets from the air stream. The purified air stream is then expelled from the device.

Abstract: This invention relates to a wet type centrifugal ‘filter less’ air cleaner. The air cleaner includes a housing having a scrubbing room associated with an air inlet and a vortex room associated with an air outlet. A reservoir is in fluid communication with the housing for supplying washing water to the air cleaner. An atomizer is in cooperation with the reservoir for producing atomized washing water to form a wet air mixture in the scrubbing room so that the atomized washing water collects the contamination in the air. A centrifugal impeller is disposed in the housing for drawing in air to create a centrifugal force on the wet air mixture. As the wet air mixture flows through the vortex room the centrifugal force separates the contaminated washing water from the purified air because of the difference between the specific gravities of the air and the washing water.

Abstract: The invention is a flue gas scrubber for removing carbon dioxide from the emissions of coal fired furnaces by induced draft of said emissions into a scrubber barrel which is positioned within the facility smoke stack.

Abstract: An aftercooler apparatus that is connected to a turbocharger and to a reciprocating engine has a primary and a secondary saturation chamber, and a drying chamber. Turbocharged air from the turbocharger is directed into the primary saturation chamber. The incoming air is initially mixed with and cooled by water located at the bottom of the primary saturation chamber before being directed through a diffusion screen. The air exiting the diffusion screen enters the secondary saturation chamber where intense bubbling and foaming increases the air-water contact area to further cool the air and form an air-water mixture approaching the temperature and moisture level of saturation. The air-water mixture is then directed into the drying chamber where a majority of the moisture is removed from the air through the use of centrifugal force. The now cooler moist air is directed toward the engine intake manifold, whereby the moisture in the air stream acts to reduce the NOx formation during the combustion process.
