Patent number: 8647411Abstract: A method of removing mercury from a process gas by means of a sorbent and a filter (10) involves applying said sorbent to at least one filtering surface (12) of the filter (10). A first parameter, which is indicative of the amount of mercury that needs to be removed in said filter (10), and a second parameter, which is indicative of the amount of material that has been collected on said filtering surface (12), are measured. A measured value of said first parameter is compared to a mercury set point. When said measured value of said first parameter is higher than said mercury set point, the cleaning of said filtering surface (12) is delayed, compared to the point in time suggested by a measured value of said second parameter.Type: GrantFiled: October 16, 2009Date of Patent: February 11, 2014Assignee: ALSTOM Technology LtdInventor: Leif A.

Patent number: 8631770Abstract: A waste gas combustion method that includes providing a combustible fuel source, in which the combustible fuel source is composed of at least methane and siloxane gas. A sodium source or magnesium source is mixed with the combustible fuel source. Combustion of the siloxane gas of the combustible fuel source produces a silicon containing product. The sodium source or magnesium source reacts with the silicon containing product to provide a sodium containing glass or sodium containing silicate, or a magnesium containing silicate. By producing the sodium containing glass or sodium containing silicate, or the magnesium containing silicate, or magnesium source for precipitating particulate silica instead of hard coating, the method may reduce or eliminate the formation of silica deposits within the combustion chamber and the exhaust components of the internal combustion engine.Type: GrantFiled: February 4, 2011Date of Patent: January 21, 2014Assignee: UT-Battelle, LLCInventor: Theodore M.

Publication number: 20130340611Abstract: The invention relates to a method and apparatus for reducing nitrosamines, formed in removal of CO2 from off-gases by means of an aqueous amine solution. A substream of the aqueous amine solution, loaded with nitrosamines, is branched off from a washing fluid circulation and is concentrated by evaporating water and low-boiling constituents. The concentrated amine solution is retained at the boiling point in a unit in which a liquid phase and a vapor phase are in contact to establish a vapor/fluid equilibrium between the phases. The vapor phase is irradiated with UV light, which decomposes nitrosamines entering the vapor phase. Following decomposition of nitrosamines, the concentrated amine solution is recycled to the washing fluid circulation for further use in the scrubber.Type: ApplicationFiled: July 18, 2013Publication date: December 26, 2013Inventor: JOHANNES MENZEL

Patent number: 8580016Abstract: A bypass unit for a water vapor transfer assembly includes a main body, a check valve, and an adjustable flow regulator. The main body has a conduit formed therethrough. The check valve is in communication with the conduit. The check valve normally militates against a flow of a bypass stream through the conduit and permits the flow of the bypass stream through the conduit above a threshold flow rate. The flow regulator is in communication with the conduit. The flow regulator permits an adjustment of the flow of the bypass stream to modify the water transfer rate of the water transfer assembly.Type: GrantFiled: September 1, 2011Date of Patent: November 12, 2013Assignee: GM Global Technology Operations LLCInventors: David A. Martinchek, Thomas D. Bronchetti, Ian R. Jermy

Patent number: 8529660Abstract: A control device for a compressed air preparation device of a vehicle outputs output signals for adjusting feed phases and regeneration phases of the compressed air preparation device. A compressor feeds compressed air via an air dryer having a desiccant into a compressed air reservoir in a feed phase, and compressed air is passed out of the compressed air reservoir through the air dryer for drying the desiccant in a regeneration phase. The control device adjusts the regeneration phases depending on a current or future engine load and/or a current or future consumption of compressed air by the vehicle. In overrun phases, the desiccant can be excessively dried to a low moisture level in order to save fuel in later travel segments. Route-optimized regeneration of the desiccant as a function of engine load and/or utilization phases can also be effected.Type: GrantFiled: August 8, 2009Date of Patent: September 10, 2013Assignee: WABCO GmbHInventors: Heinrich Diekmeyer, Kevin Pendzich, Joachim Reinhardt, Wolfgang Strache

Publication number: 20130205998Abstract: Carbon dioxide is removed from a source gas stream by admission to a vessel containing a quantity of a material preferentially absorbing carbon dioxide. The carbon dioxide content of an escaping gas stream is monitored. When the carbon dioxide content of the escaping gas stream indicates that absorbent is saturated with carbon dioxide, an inlet valve is closed, and a vacuum applied, causing the carbon dioxide to be desorbed for collection.Type: ApplicationFiled: November 26, 2012Publication date: August 15, 2013Inventor: Lawrence V.
