Publication number: 20120237407Abstract: Sulfur dioxide (SO2) is removed from a carbon dioxide feed gas by maintaining the feed gas at elevated pressure(s) in the presence of oxygen (O2), water and NOx for a period of time sufficient to convert SO2 to sulfuric acid and NOx to nitric acid and produce SO2-depleted, NOx-lean carbon dioxide gas. The invention resides in separating the sulfuric and nitric acids from said SO2-depleted, NOx-lean carbon dioxide gas, and then neutralizing the acids by reaction with an alkaline sorbent in an acid/sorbent reactor system to produce sorbent-derive sulfate. The method has particular application in the removal of SO2 and NOx from flue gas produced by oxyfuel combustion of a carbonaceous fuel.Type: ApplicationFiled: May 30, 2012Publication date: September 20, 2012Applicant: Air Products and Chemicals, Inc.Inventors: Vincent White, Kevin Boyle Fogash, Francis Peter Petrocelli

Publication number: 20120213690Abstract: Sulfur dioxide (SO2) may be removed from carbon dioxide feed gas by contacting the carbon dioxide at an elevated temperature and an elevated pressure with a catalyst for oxidizing SO2, in the presence of oxygen (O2) to convert SO2 to sulfur trioxide (SO3); contacting SO3 in the resultant SO3-enriched carbon dioxide gas with water to produce sulfuric acid and SO2-depleted carbon dioxide gas; and separating the sulfuric acid from the SO2-depleted carbon dioxide gas. If present, NOx is also removed from the carbon dioxide feed gas as nitric acid to produce SO2-depleted, NOx-lean carbon dioxide gas. The method has particular application in the removal of SO2 and NOx from flue gas produced by oxyfuel combustion of a hydrocarbon fuel or carbonaceous fuel, within or downstream of the CO2 compression train of a CO2 recovery and purification system.Type: ApplicationFiled: May 2, 2012Publication date: August 23, 2012Applicant: AIR PRODUCTS AND CHEMICALS, INC.Inventors: Francis Peter Petrocelli, Kevin Boyle Fogash, Vincent White

Patent number: 8173090Abstract: Sulfur dioxide (SO2) is removed from carbon dioxide feed gas comprising SO2 as a contaminant by maintaining the carbon dioxide feed gas at an elevated pressure in contact with an alkaline sorbent for a period of time sufficient to react said alkaline sorbent with SO2. Where NOx, oxygen (O2) and water are also present, not only is the rate of reaction with the sorbent increased, but also additional SO2 is removed by conversion to sulfuric acid, and NOx is removed as nitric acid. The method has particular application in the removal of SO2 and NOx from flue gas produced by oxyfuel combustion of a hydrocarbon or carbonaceous fuel.Type: GrantFiled: July 8, 2010Date of Patent: May 8, 2012Assignee: Air Products and Chemicals, Inc.Inventors: Francis Peter Petrocelli, Kevin Boyle Fogash, Vincent White

Patent number: 7010555Abstract: A system and method for incrementally compacting a computer system heap is presented. A heap, such as a garbage-collected heap in a Java environment, is divided into logical regions. When the heap is becoming fragmented, an incremental compaction cycle is commenced. During a first time period, the first region of the heap is compacted, with subsequent regions being compacted during subsequent time periods. A time period commences when a garbage collection event occurs. In a multiprocessor environment the regions can be divided into a number of sections which are each compacted using a different processor. One or more break tables are constructed indicating how far contiguous groups of moveable objects should be moved to better group objects and eliminate interspersed free spaces. References throughout the heap that point to objects within the compacted region are then adjusted so that the references point to the new object locations.Type: GrantFiled: October 17, 2002Date of Patent: March 7, 2006Assignee: International Business Machines CorporationInventors: Geoffrey Owen Blandy, Robert Tod Dimpsey, Kean G.

Patent number: 6593573Abstract: An apparatus for monitoring the distribution of a chemical species within a defined space, for example a vessel such as an internal combustion engine cylinder. A plurality of radiation sources and radiation detectors are distributed around the perimeter of the vessel. The radiation sources are distributed to emit beams of radiation across the interior of the vessel, the wavelength of the radiation being selected such that an interaction such as fluorescence or absorption occurs between the radiation and the chemical species which can be detected by the detectors. A representation of the distribution of the chemical species within the vessel can then be derived from the detected interactions by conventional tomography techniques.Type: GrantFiled: July 16, 2001Date of Patent: July 15, 2003Assignee: The University of Manchester Institute of Science and TechnologyInventors: Hugh McCann, Krikor Bertch Ozanian, Stephen John Carey, Francis Peter Hindle
