Patent number: 11724284Abstract: The method of the invention relates to a method of manufacturing a fibrous, oxygen barrier film by casting a suspension comprising microfibrillated cellulose onto a non-porous substrate in a number of subsequent steps with intermediate drying. The invention enables an efficient method to manufacture an MFC film by casting technology without the problems of cracks or voids formed in the film. By applying the MFC in several layers, with in-between drying, the distance the water has to diffuse through is shorter, whereby the evaporation is more efficient and the film properties are not negatively affected by the drying.Type: GrantFiled: January 30, 2018Date of Patent: August 15, 2023Assignee: Stora Enso OYJInventors: Lars Axrup, Isabel Knöös, Christian Aulin, Magnus Hillergren, Tom Lindström, Göran Ström

Patent number: 8425670Abstract: The invention refers to a plant and a method for separating oil in form of particles and/or mist from a fossil gas mixture for obtaining a separated gas. The plant comprises a centrifugal separator with a stationary casing defining a separation space. The casing permits a pressure of at least 10 bars in the separation space. The centrifugal separator comprises an inlet for the gas mixture, a gas outlet for the separated gas and an oil outlet for discharging separated oil. A separating member for separating the gas mixture comprises a plurality of separating discs and is provided in the separation space. A drive motor is connected to the separating member via a spindle and rotate the separating member about an axis (x) of rotation.Type: GrantFiled: January 26, 2010Date of Patent: April 23, 2013Assignee: Alfa Laval Corporate ABInventors: Claes-Göran Carlsson, Göran Ström

Patent number: 7152589Abstract: Upon cleaning of crankcase gas generated during operation of an internal combustion engine in its crankcase, a centrifugal separator is used, which includes a rotor arranged for rotation by means of a driving motor and arranged by its rotation suck crankcase gas from the crankcase through a conduit to the centrifugal separator. During operation of the combustion engine a parameter, e.g. a measurement of the load on the combustion engine is sensed, the magnitude of said parameter being related to the amount of crankcase gas generated per unit of time in the crankcase. Depending upon a sensed change of the sensed parameter the rotational speed of the rotor of the centrifugal separator is changed in a way such that the gas pressure in the crankcase is maintained at a predetermined value, or within a predetermined pressure interval, during the operation of the combustion engine.Type: GrantFiled: June 17, 2003Date of Patent: December 26, 2006Assignee: Alfa Laval Corporate ABInventors: Mats Ekeroth, Claes-Goran Carlsson, Rolf Ridderstrale, Jan Skoog, Goran Strom, Claes Wase
