Publication number: 20130167719Abstract: A visual indicator device and method for determining the presence of oily contaminants in a gaseous stream are provided. The device includes a filtration status chamber for receiving and discharging the gaseous stream, and a transparent wall enabling viewing of the chamber interior. A fluid-pervious filtration media within the chamber is infused with an absorption composition at which the contaminant on contact with the media is immobilized. The media has a surface viewable through a transparent wall of the filtration status chamber, and the stream flow path is such as to cause the stream to impinge at the media via the said surface, whereby the contaminants collect selectively at the media surface and are therefore highly visible through the transparent wall.Type: ApplicationFiled: February 13, 2013Publication date: July 4, 2013Applicant: MYCELX TECHNOLOGIES CORPORATIONInventor: Mycelx Technologies Corporation

Patent number: 8465006Abstract: The productivity of a combined heat and mass transfer device is improved by directing a flow of a carrier-gas mixture through a fluid flow path in a combined heat and mass transfer device operating at a pressure below atmospheric pressure. Heat and mass are transferred from or to the carrier-gas mixture by a direct or indirect interaction with a liquid composition that includes a vaporizable component (e.g., water) in a liquid state to substantially change the content of the vaporizable component in the carrier-gas mixture via evaporation of the vaporizable component from the liquid composition or via condensation of the vaporizable component from the carrier-gas mixture, producing a flow of carrier-gas mixture having a concentration of the vaporizable component that differs from the concentration of the vaporizable component in the carrier-gas mixture before the heat and mass transfer process.Type: GrantFiled: September 21, 2012Date of Patent: June 18, 2013Assignees: Massachusetts Institute of Technology, King Fahd Univeristy of Petroleum and MineralsInventors: Mostafa H. Elsharqawy, John H. Lienhard, Syed M. Zubair, Prakash N. Govindan

Patent number: 8419844Abstract: A moisture removal system for removing water moisture from an air stream and an associated method are provided. The moisture removal system includes one or more packed beds that include a water-entry surface at which liquid water is received and an air-entry surface that is located substantially opposite the water-entry surface and at which the air stream is received. The air stream passes through the one or more packed beds in a direction substantially counter-current to the passage of the liquid water and the liquid water and the air stream contact one another in the one or more packed beds resulting in the removal of at least a portion of the water moisture from the air stream. The moisture removal system can be located upstream of and be operably connected to the inlet of a gas turbine system to which the air stream is delivered from the moisture removal system.Type: GrantFiled: October 3, 2011Date of Patent: April 16, 2013Inventors: Abhijeet Madhukar Kulkarni, Richard Michael Ashley Mass, John Carl Davies

Patent number: 8387545Abstract: A method for introducing flue gas in a steam-assisted production facility into a vapor-liquid contactor. In this method the flue gas comprises boiler combustion products selected from at least one of commercial pipeline natural gas and produced gas. The flue gas is cooled with the vapor-liquid contactor to condense a portion of the water vapor in the flue gas to produce a water stream. The water stream is then recirculated and cooled in an air cooler to produce recirculating water exiting the bottom of the vapor-liquid contactor. A water slipstream is then taken off the recirculating water to be used as make-up water.Type: GrantFiled: July 15, 2010Date of Patent: March 5, 2013Assignee: ConocoPhillips CompanyInventors: Edward G. Latimer, Christopher R. Copeland, Ryan K. Davis, James Scinta, Dale L. Embry, David C. Lamont, Charles J. Murray, Ryan D. Donahe

Patent number: 8353980Abstract: An apparatus and process for removing acidic gases from flue gases produced by, for example, utility and industrial facilities. The acidic gases are removed as the flue gas flows upward through a contact zone within a passage, where the flue gas is contacted with an ammonium sulfate-containing scrubbing solution to absorb the acidic gases from the flue gas. The scrubbing solution and absorbed acidic gases therein are then accumulated, and ammonia and an oxygen-containing gas are injected into the accumulated scrubbing solution to react the absorbed acidic gases and produce ammonium sulfate. An acid solution is flowed across the passage above the contact zone of the passage, and the scrubbed flue gas is flowed upward through the acid solution to remove unreacted ammonia from the scrubbed flue gas. The acid solution is then removed from the passage after the acid solution has been contacted by the scrubbed flue gas.Type: GrantFiled: December 3, 2009Date of Patent: January 15, 2013Assignee: Marsulex Environmental Technologies CorporationInventor: David William Murphy

Patent number: 8343256Abstract: An integrated contaminant separator and water-control loop (10) decontaminates a fuel reactant stream of a fuel cell (12). Water passes over surfaces of an ammonia dissolving means (61) within a separator scrubber (58) while the fuel reactant stream simultaneously passes over the surfaces to dissolve contaminants from the fuel reactant stream into the water. An accumulator (68) collects the separated contaminant stream, and ion exchange material (69) integrated within the accumulator removes contaminants from the stream. A water-control pump (84) directs flow of a de-contaminated water stream from the accumulator (68) through a water-control loop (78) having a heat exchanger (86) and back onto the scrubber (58) to flow over the packed bed (62). Separating contaminants from the fuel reactant stream and then isolating and concentrating the separated contaminants within the ion exchange material (69) minimizes cost and maintenance requirements.Type: GrantFiled: December 27, 2007Date of Patent: January 1, 2013Assignee: UTC Power CorporationInventors: Michael T.
