Patent number: 10781498Abstract: 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 and a gas-conducting system for gases that occur when producing the pig iron and/or producing the crude steel. According to the invention, the plant complex additionally has a chemical plant or biotechnological plant, connected to the gas-conducting system, and also energy storage for covering at least part of the electricity demand of the plant complex. Also the subject of the invention is a method for operating the plant complex.Type: GrantFiled: December 11, 2014Date of Patent: September 22, 2020Assignee: THYSSENKRUPP AGInventors: Reinhold Achatz, Jens Wagner, Markus Oles, Peter Schmöle, Ralph Kleinschmidt, Christoph Meißner, Niels Bredemeyer, Johannes Völkl

Patent number: 10399952Abstract: During start-up of a continuous epoxidation of propene with hydrogen peroxide in a methanol solvent with a shaped titanium silicalite catalyst in a tube bundle reactor with a cooling jacket, cooling medium is fed at the rate for full load of the reactor with a constant entry temperature of from 20° C. to 50° C., methanol solvent is fed at a rate of from 50 to 100% for full load of the reactor, hydrogen peroxide is fed at a rate that starts with no more than 10% of the rate for full load and is increased continuously or stepwise to maintain a maximum temperature in the fixed bed of no more than 60° C. and a difference between the maximum temperature in the fixed bed and the cooling medium entry temperature of no more than 20° C., and propene is fed at a rate of from 20 to 100% of the rate for full load, increasing the feeding rate when the molar ratio of propene to hydrogen peroxide reaches the molar ratio for full load.Type: GrantFiled: March 10, 2017Date of Patent: September 3, 2019Assignees: Evonik Degussa GmbH, thyssenkrupp Industrial Solutions AGInventors: Wolfgang Wöll, Marc Brendel, Bernd Jaeger, Niels Bredemeyer, Bärbel Kolbe, Norbert Ullrich, Maik Bernhard

Publication number: 20190267648Abstract: A method for determining a charge state of a vanadium redox flow cell may comprise indirectly determining concentrations of V4+ and V5+ in a positive electrolyte by mixing positive and negative electrolytes with one another in particular proportions to reduce V5+ present in the positive electrolyte. In this way, CT complexes of V4+/V5+ may be avoided, the concentration of which is not determinable directly owing to the strong UV/vis absorption. Furthermore, the method enables determination of the concentrations of the negative electrolyte and positive electrolyte via UV/vis absorptions, which enables simple monitoring of the charge state of a vanadium redox flow battery.Type: ApplicationFiled: September 8, 2017Publication date: August 29, 2019Applicants: thyssenkrupp Industrial Solutions AG, thyssenkrupp AGInventors: Stefan HELMLE, Niels BREDEMEYER, Gregor Damian POLCYN, Nils TENHUMBERG

Patent number: 10214504Abstract: Propene is continuously reacted with hydrogen peroxide in a tube bundle reactor comprising a multitude of parallel reaction tubes in the presence of a titanium silicalite catalyst arranged as a fixed bed in the reaction tubes. A cooling jacket encloses the reaction tubes, which has a feed point for cooling medium near the entry of the reaction tubes, a withdrawal point for cooling medium near the end of the reaction tubes and at least one additional withdrawal point upstream of the withdrawal point near the end of the reaction tubes. Cooling medium is fed to the feed point for cooling medium, a part of the cooling medium is withdrawn at the at least one additional withdrawal point and the remainder exits at the withdrawal point near the end of the reaction tubes.Type: GrantFiled: November 1, 2016Date of Patent: February 26, 2019Assignees: Evonik Degussa GmbH, thyssenkrupp Industrial Solutions AGInventors: Marc Brendel, Manfred Bärz, Johannes Kowoll, David Bolz, Willi Hofen, Jürgen Schemel, Bernd Jaeger, Niels Bredemeyer, Bärbel Kolbe, Norbert Ullrich, Michael Dopfer, Wolfgang Wöll, Peter Porscha, Dana Pfenning, Maik Bernhard

Patent number: 9680172Abstract: Flow type electrochemical cells are disclosed. The electrochemical cell has an anode half-cell, a cathode half-cell, and permeable separating layer. The half-cells are bounded by side elements. Respective porous electrodes are housed in the half-cells. The permeable separating layer is disposed between the anode half-cell and the cathode half-cell. An electrolyte region connected to an electrolyte feed and an electrolyte outflow region connected to an electrolyte drain are further provided. An electrolyte inflow region and an electrolyte outflow region are disposed on opposite sides of the porous electrodes such that inflowing electrolyte flows through the porous electrode perpendicularly to the permeable separating layer.Type: GrantFiled: August 29, 2013Date of Patent: June 13, 2017Assignee: ThyssenKrupp Industrial Solutions AGInventors: Gregor Damian Polcyn, Niels Bredemeyer, Christoph Roosen, Dmitri Donst, Peter Toros, Peter Woltering, Dirk Hoormann, Philipp Hofmann, Stephan Köberle, Frank Funck, Wolfram Stolp, Bernd Langanke
