Patent number: 10589994Abstract: A burner for producing synthesis gas by partial oxidation of liquid or gaseous, carbon-containing fuels in the presence of an oxygen-containing oxidant and a moderator, which burner can be operated uncooled, i.e. without a fluid coolant being passed through the burner, is proposed. Steam or carbon dioxide or else mixtures of these materials are used as moderator. This is achieved by the feed channels being configured so that mixing of the fuel, the moderator and the oxidant occurs only outside the burner.Type: GrantFiled: May 11, 2018Date of Patent: March 17, 2020Assignee: L'Air Liquide Societe Anonyme Pour L'Etude Et L'Exploitation Des Procedes Georges ClaudeInventors: Joerg Ott, Veronika Gronemann, Maik Lehmann, Paul Manfred Krimlowski

Patent number: 10364202Abstract: The invention relates to a process and a plant for the methanol synthesis, in particular for the methanol synthesis from a synthesis gas which has a hydrogen deficiency. According to the invention, a purge gas stream therefor is branched off from the synthesis gas circuit of the methanol synthesis, liberated from methanol traces in a washing device, and then treated in a hydrogen separation device which comprises a membrane separation stage and a pressure swing adsorption stage. Depending on the application and magnitude of the hydrogen deficit the membrane separation stage and the pressure swing adsorption stage can be connected in series or in parallel.Type: GrantFiled: March 6, 2017Date of Patent: July 30, 2019Assignee: L'Air Liquide Societe Anonyme Pour L'Etude Et L'Exploitation Des Procedes Georges ClaudeInventors: Hans Kopetsch, Veronika Gronemann, Tobias Oelmann

Patent number: 10259708Abstract: There is proposed a method for starting up a pre-reforming stage in an integrated reforming plant in which a hydrocarbonaceous feed stream, in particular natural gas, is converted into a reformation product containing carbon oxides, hydrogen and hydrocarbons. Before carrying out the start-up method, the catalyst contained in the pre-reforming stage is in an oxidized or passivated state. For its activation, the pre-reforming catalyst is charged with a methanol/steam mixture, from which by steam reformation of methanol in situ the hydrogen required for the activation of the catalyst is produced. Excess hydrogen is used for the hydrogen supply of the desulfurization stage arranged upstream of the pre-reforming stage.Type: GrantFiled: May 5, 2014Date of Patent: April 16, 2019Assignee: L'Air Liquide Societe Anonyme pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Veronika Gronemann, Jorg Ott, Theis Ohlhaver, Paul Krimlowski

Patent number: 9701600Abstract: During the production of methanol from inert-rich syngas, a catalytic pre-reactor is installed upstream of the single- or multi-stage synthesis loop, a first part of the syngas being converted to methanol in the catalytic pre-reactor. An inert gas separation stage, for example a pressure swing adsorption system or a membrane system, can be connected downstream of the synthesis loop, whereby a hydrogen-enriched syngas stream can be returned to the synthesis loop. In the processing of methane-rich syngas, the inert gas separation stage may also have an autothermal reformer in which methane is converted to carbon oxides and hydrogen, which are also returned into the synthesis loop.Type: GrantFiled: December 2, 2015Date of Patent: July 11, 2017Assignee: AIR LIQUIDE GLOGAL E&C SOLUTIONS GERMANY GMBHInventors: Philipp Marius Hackel, Rainer Morgenroth, Andreas Bormann, Veronika Gronemann

Publication number: 20160039670Abstract: For producing a synthesis gas containing hydrogen and carbon monoxide from a starting gas containing hydrocarbons, the starting gas is split up into a first partial stream and a second partial stream, wherein the first partial stream is supplied to a steam reformer in which it is catalytically converted together with steam to obtain a gas stream containing hydrogen and carbon oxides, wherein after the steam reformation the first partial stream is again combined with the second partial stream, and wherein the combined gas stream is supplied to an autothermal reformer in which the combined gas stream together with an oxygen-containing gas is autothermally reformed to a synthesis gas. The first partial stream is guided directly into the steam reformer and the second partial stream is guided through a pre-reformer before passing through the autothermal reformer.Type: ApplicationFiled: February 11, 2014Publication date: February 11, 2016Applicant: L'Air Liquide, Societe Anonyme pour I'Etude et I'Exploitation des Procedes Georges ClaudeInventors: Tobias OELMANN, Dierk MULLER, Veronika GRONEMANN

Patent number: 9040594Abstract: A method for producing methanol from a synthesis gas containing hydrogen and carbon oxides with a high content of inert components includes passing the synthesis gas through a synthesis reactor so as to catalytically convert a part of the carbon oxides to methanol. The methanol is separated from the obtained mixture from the reactor. The mixture liberated from methanol is separated into a cycle stream and a purge stream. The cycle stream is recirculated so as to form a synthesis circle and combined with a fresh gas stream including hydrogen and carbon oxides before being charged into the synthesis reactor. The purge stream is supplied to a secondary reactor so as to catalytically convert a further part of the hydrogen and carbon oxides to methanol. Further methanol is separated the obtained mixture including synthesis gas, inert components and methanol vapor.Type: GrantFiled: July 16, 2010Date of Patent: May 26, 2015Assignee: AIR LIQUIDE GLOBAL E&C SOLUTIONS GERMANY GMBHInventors: Andreas Bormann, Veronika Gronemann, Rainer Morgenroth, Jan Hagemann, Holger Schlichting, Philipp Marius Hackel

Patent number: 8884074Abstract: A process produces dimethyl ether (DME) from methanol (MeOH). The process includes charging a feed mixture consisting of raw MeOH and a process-internally obtained return flow substantially consisting of unconverted MeOH and reaction water to an MeOH column. The feed mixture is evaporated in the MeOH column to form a first distillate substantially consisting of vaporous MeOH. The first distillate is supplied to a reactor and the MeOH is converted to DME by splitting off water in the reactor so as to form a reaction mixture. The reaction mixture is withdrawn from the reactor, charged to a mixture column and separated into a bottom product substantially consisting of water and a second distillate substantially consisting of DME and MeOH. The second distillate is separated in a DME column into a third distillate substantially consisting of DME, a bottom product consisting essentially of water-poor MeOH, and uncondensable gases discharged overhead.Type: GrantFiled: November 19, 2009Date of Patent: November 11, 2014Assignee: Air Liquide Global E&C Solutions Germany GmbHInventors: Bernd Ahlers, Gerhard Birke, Harald Koempel, Hermann Bach, Martin Rothaemel, Waldemar Liebner, Walter Boll, Veronika Gronemann

Patent number: 8629191Abstract: For producing methanol from a synthesis gas containing hydrogen and carbon oxides the synthesis gas is passed through a first, water-cooled reactor in which a part of the carbon oxides is catalytically converted to methanol. The resulting mixture containing synthesis gas and methanol vapor is supplied to a second, gas-cooled reactor in which a further part of the carbon oxides is converted to methanol. Subsequently, methanol is separated from the synthesis gas, and synthesis gas is recirculated to the first reactor. The cooling gas flows through the second reactor cocurrent to the mixture withdrawn from the first reactor.Type: GrantFiled: July 29, 2009Date of Patent: January 14, 2014Assignee: Lurgi GmbHInventors: Hans Kopetsch, Philipp Marius Hackel, Veronika Gronemann, Rainer Morgenroth
