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.

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. Lines, Derek W. Hildreth, John L. Preston, Jr.
