  • Patent number: 11724284
    Abstract: 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.

  • Patent number: 10138599
    Abstract: The present invention relates to process for the production of a coated substrate comprising cellulosic fibers, the process comprising the steps of: i) providing a first substrate comprising cellulosic fibers and having a dry content of less than 50%; ii) applying a coating composition to the first substrate in an amount of more than 5 g/m2, calculated as dry weight of the coating composition, wherein the coating composition comprises: microfibrillated cellulose (MFC), and optionally a water retention agent selected from carboxymethyl cellulose (CMC), anionic polyacrylamide (A-PAM), sodium polyacrylates, polyacrylic acid derivatives, guar gum, alginate, MFC prepared from carboxymethylated fibers, MFC prepared from oxidized fibers, MFC prepared by CMC-functionalized fibers, and/or combinations thereof; and iii) mechanically dewatering the first substrate. The present process provides an energy efficient coating process which can be performed online.

  • Patent number: 8425670
    Abstract: 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.

  • Patent number: 7152589
    Abstract: 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.

  • Patent number: 5914413
    Abstract: The invention concerns a gas filter unit or cartridge type, including a filter material put together to form one or several filter bags, and a support frame of essentially U-shaped cross-sectional configuration, including a web portion and two lateral leg members in adjoining relationship, the filter material closest to the mouths of the filter bags being clamped in position between said lateral leg members. In accordance with the invention, the frame includes profile sections of a flexible material, preferably a plastics material, at least one of said lateral leg members being hingedly interconnected with the web portion, in addition to which locking means are provided to retain the corresponding lateral leg member in its clamping position in which it is pivoted into engagement with the other lateral leg member.
