Patent number: 11465082Abstract: A filtration assembly structured to filter reductant includes an outer housing and an inner housing. The inner housing is positioned within the outer housing. The inner housing is structured to contain the reductant and operable between a first state in which the inner housing has a first volume and a second state in which the inner housing has a second volume that is larger than the first volume, the inner housing including an end face. The inner housing is separated from the outer housing by a gap when the inner housing is in the first state. A volume of the gap decreases as the inner housing transitions from the first state to the second state and increases as the inner housing transitions from the second state to the first state.Type: GrantFiled: February 15, 2018Date of Patent: October 11, 2022Assignee: Cummins Emission Solutions Inc.Inventors: Julian Nicolas Aljoscha Raupp, Friedrich Johann Zapf, Ralf Rohrmueller, Andreas Lannig, Thomas Betz, Kay Henning Schmidt

Patent number: 8931262Abstract: A method for controlling the effective heat transfer from a storage unit (1). During gas release from storage material (3) in the storage unit the storage material is heated by a heater (2). During re-saturation of the storage material (3) with gas the heater is off. Controlling of the effective heat transfer from the storage unit (1) is performed, during gas release, by ceasing convection of a convection gas and, during re-saturation, by performing or enabling convection of a convection gas to cool the storage unit (1).Type: GrantFiled: March 16, 2011Date of Patent: January 13, 2015Assignee: Amminex Emissions Technology A/SInventors: Ulrich Joachim Quaade, Tue Johannessen, Jacob Hjerrild Zeuthen, Henning Schmidt

Patent number: 8834603Abstract: A method is provided for estimating the degree of saturation (S) of a reversible solid ammonia storage material (3) in a storage unit (1). The storage unit (1) is equipped with a heater (2) to release ammonia and a connected tube (4) for ammonia flow. The initial temperature (TINIT) is measured with a sensor (9) in or around the storage unit (1) before any heating is initiated. Heating is initiated while recording the active time of heating (t) or the amount of energy (Q) released by the heater. The desorption pressure created by solid storage material in the storage unit (1) is measured via a pressure sensor (8) in fluid communication with the storage unit (1). The time (tTARGET), or the heat (QTARGET) where the pressure reaches a certain target pressure (PTARGET) is recorded. The values of the target-pressure time (tTARGET), or the target-pressure heat (QTARGET), and the initial temperature (TINIT) are used to compute an approximate degree of saturation (S).Type: GrantFiled: February 14, 2011Date of Patent: September 16, 2014Assignee: Amminex Emissions Technology A/SInventors: Tue Johannessen, Johnny Johansen, Jacob Hjerrild Zeuthen, Henning Schmidt, Ulrich Joachim Quaade

Patent number: 8578702Abstract: A method of storing and delivering ammonia and the use of electromagnetic radiation for desorption of ammonia from a chemical complex. Solid metal ammine complexes are applied for safe and high-density storage of ammonia to be released for use as reducing agent in selective catalytic reduction of NOx in exhaust gases. The compositional formula of the metal ammine complexes is M(NH3)nXz, where M2+ represents one or more metal ions capable of binding ammonia, X represents one or more anions, n is the coordination number (from 2 to 12), and z the valency of the metal ion (and thus the total number of compensating anion charges). Ammonia is released non-thermally by photon-activation using electromagnetic irradiation of the complex bond between ammonia coordinated to the metal ion.Type: GrantFiled: February 27, 2007Date of Patent: November 12, 2013Assignee: Amminex Emissions Technology A/SInventors: Tue Johannessen, Rasmus Zink Sørensen, Claus Hviid Christensen, Ulrich Quaade, Jens Kehlet Nørskov, Henning Schmidt

Patent number: 8491842Abstract: A system for storage and dosing of ammonia, including a solid ammonia storage material capable of binding and releasing ammonia reversibly by adsorption/absorption. The system is able to release ammonia gradually according to a demand that can vary over time with intermediate periods of no ammonia demand. A main storage unit and a start-up storage unit are provided. The storage units hold ammonia storage material. At least one one-way valve is provided via which the one main storage unit is in communication with the start-up storage unit. The one-way valve prevents any back-flow of ammonia from the start-up storage unit to the main storage unit. Heating devices are arranged to heat the main storage unit and the start-up storage unit separately to generate gaseous ammonia by thermal desorption from the solid storage material.Type: GrantFiled: September 3, 2009Date of Patent: July 23, 2013Assignee: Amminex Emissions Technology A/SInventors: Johnny Johansen, Jan Oechsle, Henning Schmidt, Tue Johannessen, Jakob Svagin

Publication number: 20100050615Abstract: Solid metal ammine complexes are applied for safe and high-density storage of ammonia to be released for use as reducing agent in selective catalytic reduction of NOx in exhaust gases or as an energy carrier for fuel cell applications. The compositional formula of the metal ammine complexes is M(NH3)nXz, where Mz+ represents one or more metal ions capable of binding ammonia, X represents one or more anions, n is the coordination number (from 2 to 12), and z the valency of the metal ion (and thus the total number of compensating anion charges). Ammonia is released by controlled dosing of water into the storage container whereby ammonia is released because water replaces ammonia on the active sites capable of binding ammonia. Consequently, ammonia can be released without applying a normal thermal desorption of ammonia and the operating temperature of the system is reduced as well as the energy needed for releasing ammonia.Type: ApplicationFiled: July 19, 2007Publication date: March 4, 2010Applicant: Gladsaxevej 363Inventors: Tue Johannessen, Henning Schmidt, Jens Kehlef Norskov, Claus Hviid Christensen
