Martin Muller-Hasky has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Gas scrubber having an integrated heat exchanger
    Patent number: 8974584
    Abstract: A gas scrubber, equipped with heat exchanger surfaces constructed of thermoplates, suitable for cooling and cleaning a hot gas by avoiding an excessive thermal load of the washing liquid.
    Type: Grant
    Filed: September 24, 2010
    Date of Patent: March 10, 2015
    Assignee: Lurgi GmbH
    Inventors: Frank Castillo-Welter, Christoph Steden, Dominic Walter, Georg Ehring, Martin Müller-Hasky
  • Method for continuously producing melamine
    Patent number: 8431696
    Abstract: A process for the continuous production of melamine from urea by means of a fluidized-bed reactor, wherein process gas guided in the process circuit is used as fluidizing gas and wherein the temperature of the process gas at the inlet of the conveying means for the fluidizing gas is adjusted by adjusting the mixing ratio of a process gas stream guided over a scrubber and of a process gas stream guided past the scrubber.

  • Method for producing melamine
    Patent number: 8058428
    Abstract: The invention concerns a method for producing melamine by dissolving urea, in which solid, liquid or gaseous media other than the gas mixture consisting of the components formed during the reaction is used to desublime the melamine from the gas phase.
    Type: Grant
    Filed: February 27, 2006
    Date of Patent: November 15, 2011
    Assignee: Lurgi AG

  • Method for producing melamine with heat recovery
    Patent number: 7977479
    Abstract: The invention relates to a method for producing melamine by decomposing urea inside a fluidised bed reactor, during which the hot reaction gas is cooled inside a gas cooler, and the obtained heat is directly used for pre-heating the fluidizing gas required for creating the fluidized bed.
