    摘要: Both power and H2 are produced from a gaseous mixture, comprising H2 and CO2, using first and second pressure swing adsorption (PSA) systems in series. The gaseous mixture is fed at super-atmospheric pressure to the first PSA system, which comprises adsorbent that selectively adsorbs CO2 at said pressure, and CO2 is adsorbed, thereby providing an H2-enriched mixture at super-atmospheric pressure. A fuel stream is formed from a portion of the H2-enriched mixture, which is combusted and the combustion effluent expanded to generate power. Another portion of the H2-enriched mixture is sent to the second PSA system, which comprises adsorbent that selectively adsorbs CO2 at super-atmospheric pressure, and CO2 is adsorbed, thereby providing a high purity H2 product. In preferred embodiments, the division of H2-enriched mixture between forming the fuel stream and being fed to the second PSA system is adjustable.

    摘要: According to an embodiment, a method of operating an oxy/fuel system and an oxy/fuel system circulate a support gas in the combustion system prior to activating at least one burner, produce the combustion fluid including CO2, wherein a level of the CO2 in the combustion fluid increases as a function of time, and continue production of the combustion fluid to exceed a predetermined level of the CO2 in the combustion fluid, for a period of time, the predetermined level being sufficient to permit the CO2 to be purified by a CO2 purification unit.

    摘要: SO2 and/or NOx are removed from gaseous CO2 at elevated pressure(s) in the presence of molecular oxygen and water and, when SO2 is to be removed, NOx, to convert SO2 to sulfuric acid and/or NOx to nitric acid. The sulfuric acid and/or nitric acid is/are then removed from the gaseous carbon dioxide to produce SO2-free, NOx-lean carbon dioxide gas. The invention has particular application in the removal of SO2 and/or NOx from carbon dioxide flue gas produced in an oxyfuel combustion process, for example, in a pulverized coal fired power station.
