Publication number: 20120009107Abstract: 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: ApplicationFiled: July 8, 2010Publication date: January 12, 2012Applicant: AIR PRODUCTS AND CHEMICALS, INC.Inventors: Francis Peter Petrocelli, Kevin Boyle Fogash, Vincent White

Patent number: 8091369Abstract: A superheater in a power plant that superheats steam to operation conditions exceeding an operating limit of an associated steam-producing boiler. The superheater combusts oxygen and fuel with cooled recycled combustion gas to produce a CO2-rich combustion product gas stream at a fixed temperature. The combustion gas is used as the heat transfer fluid in the superheater's heat exchanger. The CO2-rich flue gas stream allows for efficient capture of substantially pure CO2. The superheater may be retrofitted to an existing power plant as a separate component, external to the boiler. The plant may thus have its electrical power output increased, while its overall CO2 emissions per nit of generated power is decreased, even when inexpensive, readily-available fossil fuels are used as the primary fuel for filing the boiler and/or the superheater.Type: GrantFiled: July 11, 2008Date of Patent: January 10, 2012Assignee: Air Products and Chemicals, Inc.Inventors: Rodney John Allam, Vincent White, Julia Elizabeth Milligan
