  • 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.

    Abstract: An engine crankcase breather for oil segregation, from blow-by gases, in an engine. The engine crankcase breather includes a housing with an inlet located in a downstream direction of the blow-by gases and an outlet. The breather also includes a baffle within the housing which poses a tortuous path for the blow-by gases, in order to segregate oil particles from the blow-by gases. The baffle includes a hook-shaped portion, in which the oil segregation takes place. The engine crankcase breather further includes a trough extending within the housing.

  • Patent number: 8317905
    Abstract: Fine, solid particles in a gas stream, especially fly ash particles in the hot gas stream from a coal/coke-utilizing synthesis gas unit, are agglomerated by passage through a gas flow matrix element having a body with confined gas flow channels which bring the particles into close proximity to one another in an environment of low turbulence; a rough surface on the gas flow passages provides surface induction to promote agglomeration of the particles. The larger, agglomerated particles may then be removed from the gas stream by inertial separators such as cyclones.

  • Patent number: 8313566
    Abstract: Devices, systems, and methods improve particulate filtration. A particulate filtration system is implemented within a fossil fuel power plant combustion system. A gas containing particulates flows through the filtration system. The filtration system comprises a collection hopper for collecting the particulates. Within the collection hopper, a particulate trap, upper baffles, and lower baffles are provided to retain collected particulates in the hopper and, thereby, improve the filtration of particulates from the gas flow. The particulate trap can include two sets of variously oriented, interconnecting retaining members crossing the interior of the collection hopper.

  • Publication number: 20120186451
    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.
