Publication number: 20180028964Abstract: The present application provides a wet scrubber system for treating a flow of flue gases with dioxins therein with a flow of a fluid. The wet scrubber system may include a column member, a packed bed positioned within the column member, and an activated carbon filter bed system in communication with the column member such that at least a portion of the flow of the fluid passes through the activated carbon filter bed system to remove the dioxins therein before being recirculated back to the column member.Type: ApplicationFiled: July 29, 2016Publication date: February 1, 2018Inventors: Ghazale Hosseinzadeh Attar Nilsson, Anders Ljungberg, Daniel Per Niklas Persson, Erland Leif Klintenheim

Publication number: 20150203657Abstract: The present invention refers to a plasticiser, said plasticiser being an ester formed by reaction of a pentaerythritol and a monocarboxylic acid, having 4-5 carbon atoms. In a further aspect the present invention refers to the use of said plasticiser in blends and in a PVC resin. The plasticiser of the present invention is a non-phthalic plasticiser that has proven to have shorter fusion time and higher plasticising efficiency compared to commercial non-phthalic PVC plasticisers.Type: ApplicationFiled: July 26, 2011Publication date: July 23, 2015Applicant: Perstorp ABInventors: Karin Ohgren Gredegard, Anders Magnuesson, Hakan Bjornberg, Niklas Persson, Maria Peterson, Kent Sorensen

Patent number: 8877152Abstract: Methods and systems for the removal of SO2 from waste combustion flue gas are described herein. One such system for removing SO2 from waste combustion flue gas containing SO2 uses a semi-dry desulfurization system for contacting the flue gas with a solvent moistened absorption material. Thereafter, a recirculated water quench is used for contacting the flue gas with recirculated water at a relatively low pH, followed by a condenser used for contacting the flue gas with a water spray. Additionally, a NaOH supply for supplying NaOH to the condenser and an oxidizing catalyst supply for supplying an oxidizing catalyst to the condenser, are likewise used to produce cleaned flue gas for release to the atmosphere.Type: GrantFiled: March 22, 2013Date of Patent: November 4, 2014Assignee: ALSTOM Technology LtdInventors: Daniel Per Niklas Persson, Mati Maripuu, Marja Swahn

Publication number: 20060230213Abstract: A DSP system includes a DSP processor, at least one accelerator and an accelerator interface connected between the DSP processor and the at least one accelerator. The accelerator interface includes an accelerator instruction bus to convey instructions from the DSP processor to the accelerators. The DSP processor assigns an accelerator field in the instruction when the instruction is used to access the accelerators and further assigns an accelerator ID field in the instruction when the DSP processor selects a specific accelerator. The instruction also contains information to indicate a register address in the DSP processor and the command sent to the elected accelerator.Type: ApplicationFiled: March 29, 2005Publication date: October 12, 2006Inventors: Ivo Tousek, Tommy Eriksson, Niklas Persson

Patent number: 6313614Abstract: In a method for controlling a secondary voltage (US) in a transformer device connected to a power network with a given system frequency (f1), which transformer device comprises a tap-changer (TC) which, in dependence on a supplied control signal (RCS), influences the voltage ratio (RAT) of the transformer device, a voltage variable (uE) is formed in dependence on the secondary voltage. The voltage variable comprises at least one first control component (u1, &phgr;1) which represents a fundamental component of the secondary voltage, and a control quantity (EPV, EEV) is formed in dependence on the voltage variable. The control signal is formed in dependence on a deviation (DPV, DEV) between the control quantity and a given reference value (PVR, EVR) therefor and is supplied to the tap-changer. The actual fundamental frequency (f1*) of the power network is continuously sensed and the voltage variable is formed in dependence thereon.Type: GrantFiled: August 16, 2000Date of Patent: November 6, 2001Assignee: ABB ABInventors: Niklas Persson, Jonas Schenström
