Patent number: 8562925Abstract: An arrangement for controlling injection of a reducing agent in an exhaust line of a combustion engine (1): An injection system (8-12) injects the reducing agent into the exhaust line (3). A first catalyst (13) reduces the amount of nitrogen oxides in the exhaust gases in the exhaust line (3) using the reducing agent. A second catalyst (14) downstream of the first catalyst (13) in the exhaust line (3) converts ammonia in the exhaust gases to nitrogen gas and nitrous oxide. A nitrous oxide sensor (17) monitors the amount of nitrous oxide in the exhaust line (3) downstream of the second catalyst (14). A control unit (10) of the injection system (8-12) adjusts the amount (q) of reducing agent injected into the exhaust line (3) if the sensor (17) detects that the amount of nitrous oxide is not within a selected range (A).Type: GrantFiled: July 11, 2011Date of Patent: October 22, 2013Assignee: Scania CV ABInventor: Håkan Sarby

Publication number: 20130274097Abstract: A method and apparatus for conversion of paper residue into a mineral product uses a fluidized bed device with a distribution plate for securing an even distribution and supply of at least combustion air to the bed material and to the paper residue. An air box below the distribution plate supplies combustion air to the bed material and paper residue above the distribution plate. A heat exchanging section receives in separate parts ambient air and flue gases from the fluidized bed device for exchanging heat between flue gases and ambient air. The heat exchanging section is connected to the air box for supplying the heated ambient air to the air box for use as combustion air. A control system is employed for controlling the amount of bed material and the dimension of its particles and is arranged to monitor and maintain a process parameter within a predefined range.Type: ApplicationFiled: September 26, 2012Publication date: October 17, 2013Inventor: Joseph Jan Peter Biermann

Patent number: 8557207Abstract: A method and apparatus for reducing the quantity of pollutant in waste gases, in particular for reducing the quantity of nitrogen oxide in the flue gas of a coal-fired power plant is provided. The process includes the steps of, introducing the waste gas into a catalyzer, to which a quantity of catalytic reduction agent is supplied, measuring the quantity of pollutant at the outlet of the catalyzer, and setting the quantity of pollutant to a setpoint value smaller than a limit value to be complied with, by varying the quantity of reduction agent supplied, wherein the setting of the quantity of pollutant is dynamically regulated as a function of mean values over time, for example half-hour or quarter-hour mean values, of the measured quantity of pollutant determined regularly beforehand.Type: GrantFiled: August 16, 2012Date of Patent: October 15, 2013Assignees: Siemens Aktiengesellschaft, STEAG GmbHInventors: Jürgen Endemann, Jörg Gadinger

Patent number: 8551432Abstract: A method for injecting ammonia into an exhaust gas stream downstream of a diesel engine includes providing an exhaust gas passageway (11) from the diesel engine to an ambient (14). The exhaust gas passageway (11) includes an NOx Slip Catalyst (NSC) 20 downstream of an NOx Particulate Filter (NPF) 18. The method includes emitting exhaust gas (EG) through the exhaust gas passageway (11), and selectively injecting ammonia (NH3) upstream of the NPF 18, upstream of the NSC (20), both upstream of the NPF and the NSC, or not injecting ammonia, depending on the temperature of the exhaust gas at the NPF and at the NSC.Type: GrantFiled: June 4, 2010Date of Patent: October 8, 2013Assignee: International Engine Intellectual Property Company, LLC.Inventors: Brad J. Adelman, Vadim Olegovich Strots, Shyam Santhanam
