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: 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
