Patent number: 9493408Abstract: Disclosed is a method for the removal of ammonia from the off-gas of a finishing section of a urea production plant. The method comprises contacting the off-gas with a solid adsorbent capable of physically adsorbing ammonia, particularly activated carbon or zeolite. Thereupon the solid adsorbent having ammonia adsorbed thereon is separated from the gas and regenerated by dissolving ammonia in an extraction liquid, preferably water. After separating the water from the solid adsorbent, the latter is re-used in the process.Type: GrantFiled: February 12, 2010Date of Patent: November 15, 2016Assignee: STAMICARBON B.V.Inventors: Johanna Eliasson, Ylva Eriksson, David Holmström, P. Christian Hulteberg, Hans T. Karlsson, Filip Nilsson, Frida Ojala, Johan Albert Arno Van Den Tillaart

Patent number: 8551197Abstract: A hydrogen generation system is disclosed that includes an integrated steam reforming reactor. The reactor has an overall cylindrical shape, receives a reformate and separately receiving a combustion gas mixture. The reactor includes a plurality of reforming stages arranged in a stacked series of disc shaped stage configuration, wherein each reforming stage has a disc shaped combustion portion adjacent a disc shaped catalyst pack through which the reformate passes, wherein the reformate is directed axially between stages and radially within each stage; and the combustion mixture is directed radially between groups of stages and circumferentially within each stage.Type: GrantFiled: October 17, 2006Date of Patent: October 8, 2013Assignee: Intelligent Energy, Inc.Inventors: Richard Root Woods, Brook Forest Porter, Kandaswamy Duraiswamy, Leonard Weschta, Christian Hulteberg
