Publication number: 20230044089Abstract: An apparatus for steam reforming includes a reactor, a condensate separator, a condensate stripper, and a steam boiler. The reactor produces hydrogen and is connected to the condensate separator such that a gas mixture is conducted from the reactor into the condensate separator. The condensate separator and the condensate stripper are connected so that condensate separated out in the condensate separator is conducted into the condensate stripper. The condensate separator and the steam boiler are connected such that cleaned condensate can be conducted into the steam boiler. The steam boiler is connected to the reactor and to the condensate stripper in a steam-conducting manner. The boiler water feed line of the steam boiler is connectable to the condensate stripper in a liquid-conducting manner. A supply from the boiler water feed line is at a same location of the condensate stripper as a supply of the condensate from the condensate separator.Type: ApplicationFiled: August 4, 2022Publication date: February 9, 2023Applicants: thyssenkrupp Industrial Solutions AG, thyssenkrupp AGInventors: Christoph MEISSNER, Michael LANGANKI, Bernd MIELKE, Klaus NOELKER, Lukas KUBASCH

Patent number: 10697030Abstract: The invention relates to a plant complex for steel production comprising a blast furnace for producing pig iron, a converter steel mill for producing crude steel, a gas-conducting system for gases that occur in the production of pig iron and/or in the production of crude steel, and a power-generating plant for electricity generation. The power-generating plant is operated with a gas that comprises at least a partial amount of the blast-furnace top gas that occurs in the production of pig iron and/or a partial amount of the converter gas. According to the invention, a chemical or biotechnological plant is provided and connected to the gas-conducting system and arranged in parallel with the power-generating plant with respect to the gas supply. Externally obtained electricity and power-generating plant electricity are used to cover the electricity demand of the plant complex.Type: GrantFiled: December 11, 2014Date of Patent: June 30, 2020Assignee: ThyssenKrupp AGInventors: Reinhold Achatz, Jens Wagner, Markus Oles, Peter Schmöle, Ralph Kleinschmidt, Bärbel Kolbe, Matthias Patrick Krüger, Christoph Meißner

Patent number: 10618817Abstract: A method and device for producing ammonia from a syngas in a heterogeneous gas catalysis process in at least two reaction devices connected in series. Each reaction device includes at least two catalyst beds through which the syngas is conducted and in which an at least partial conversion of the syngas into the product gas is carried out. At least one first heat exchanger is provided in the first reaction device, and the fresh syngas is pre-heated in the first heat exchanger. The syngas exiting the first catalyst bed and which includes the product and non-converted reactants is cooled before entering the second catalyst bed. According to an embodiment of the invention, the pre-heating process is carried out in a first heat exchanger arranged between the first and the second catalyst bed. Thus, synthesis conversion can be increased without substantially increasing the process gas quantity.Type: GrantFiled: April 13, 2017Date of Patent: April 14, 2020Assignees: THYSSENKRUPP INDUSTRIAL SOLUTIONS AG, THYSSENKRUPP AGInventors: Christoph Meissner, Andreas Kinner, Klaus Nölker, Reinhard Heun

Patent number: 10519102Abstract: The invention relates to a process for preparing ammonia gas and CO2 for urea synthesis. In the process of the invention, a process gas containing nitrogen, hydrogen and carbon dioxide as main components is produced from a metallurgical gas. The metallurgical gas consists of blast furnace gas, or contains blast furnace gas at least as a mixing component. The process gas is fractionated to give a gas stream containing the CO2 component and a gas mixture consisting primarily of N2 and H2. An ammonia gas suitable for the urea synthesis is produced from the gas mixture by means of ammonia synthesis. CO2 is branched off from the CO2-containing gas stream in a purity and amount suitable for the urea synthesis.Type: GrantFiled: December 11, 2014Date of Patent: December 31, 2019Assignee: THYSSENKRUPP AGInventors: Christoph Meißner, Denis Krotov, Olaf von Morstein, Matthias Patrick Krüger
