Patent number: 10858598Abstract: A method for purifying an asphaltene-containing fuel where the asphaltene-containing fuel is supplied to a deasphalting unit in which asphaltene contained in the fuel is separated using a solvent, thereby forming a substantially deasphalted fuel. The solvent is separated from the deasphalted fuel in a solvent recovery unit after a successful separation of the asphaltene from the fuel, and the waste heat of turbine exhaust gas produced in a gas turbine when converting fuel into electricity is used in order to purify the asphaltene-containing fuel. A corresponding device is used for purifying an asphaltene-containing fuel.Type: GrantFiled: March 2, 2017Date of Patent: December 8, 2020Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Markus Kinzl, Ansgar Kursawe, Sebastian Löw

Patent number: 10836964Abstract: A method and a device for preparing a vanadium-containing combustible in a de-asphalting device. In this way, a vanadium-containing combustible is supplied to a de-asphalting unit via a supply line in a de-asphalting device, wherein the vanadium-containing combustible supplied into the de-asphalting unit forms a first mass flow and a substantially de-asphalted combustible is discharged from the de-asphalting unit via a discharge line. A bypass line is connected to the supply line, wherein, via the bypass line, a second mass flow of the vanadium-containing combustible is directed past the de-asphalting unit in parallel to the first mass flow and supplied to the discharge line, such that a combined mass flow is formed in the discharge line.Type: GrantFiled: June 28, 2017Date of Patent: November 17, 2020Assignee: Siemens AktiengesellschaftInventors: Markus Kinzl, Ansgar Kursawe, Sebastian Löw

Publication number: 20180148655Abstract: A method for separating asphaltenes from an asphaltene-containing fuel, wherein fuel is supplied to a separation unit in which a sub-stream with low-boiling fuel components of the fuel is separated. After separation of the sub-stream the fuel is supplied to a deasphalting unit in which asphaltenes contained in the fuel are separated by a solvent. After the separation of the asphaltenes from the fuel, the solvent is separated therefrom in a solvent recovery unit. The separated solvent is circulated back into the deasphalting unit, and a solvent fraction is obtained from the sub-stream that has been separated from the fuel, which is supplied to the deasphalting unit in addition to the solvent recirculated from the solvent recovery unit. A device is adapted for separating asphaltenes from an asphaltene-containing fuel.Type: ApplicationFiled: April 21, 2016Publication date: May 31, 2018Applicant: Siemens AktiengesellschaftInventors: Sebastian Löw, Markus Kinzl, Ralph Joh, Ansgar Kursawe, Herbert Fahrnbauer, Thomas Fuchs, Jochen Petersen, Rüdiger Schneider, Nicolas Vortmeyer

Publication number: 20060234381Abstract: A reaction system enables a plurality of optimization experiments for a reaction to be performed continuously, to enable optimal reaction parameters to be determined. Dilution pumps are included to automatically vary the solvent mixed with reactants so a concentration of each reactant can be selectively varied. The reactants are introduced into a reaction module selectively coupled to residence time chambers or directly to an analytical unit. The analytical unit determines the yield and/or quality for each optimization experiment, enabling optimal parameters to be determined. Residence time chambers can be employed sequentially to enable total residence time to be varied. The controller performs as many experiments as required to enable each parameter to be varied according to a predefined testing program and can redefine a testing program based on the results from previous experiments. At least two reaction parameters can be varied according to periodic functions to further enhance analytical efficiency.Type: ApplicationFiled: June 22, 2006Publication date: October 19, 2006Applicant: Cellular Process Chemistry, Inc.Inventors: Thomas Schwalbe, Volker Autze, Sebastian Oberbeck, Ansgar Kursawe, Kemal Sahin
