  • Patent number: 11273406
    Abstract: Method for treating impurities contained in exhaust gases of ships to reduce sulphur oxide and other emissions. In order for the method to purify wash water exiting from an exhaust gas scrubber sufficiently enough to be directly dischargeable to sea, and in order for a purification unit used to be small enough to be easily placed onboard a ship, exhaust gases are scrubbed in the exhaust gas scrubber and wash water containing impurities and exiting from the scrubber is supplied to the purification unit, circulated in an effluent circuit, and filtered through a semipermeable membrane of a filter to obtain purified effluent and a residue containing impurities, when necessary, the pH value of the purified effluent is adjusted to be at least 6.5, after which it is discharged into the sea or recycled to the scrubber while the residue containing impurities is led back to the effluent circuit.

  • Patent number: 10005020
    Abstract: A method for treating impurities contained in exhaust gases of ships to reduce sulphur oxide and other emissions, includes scrubbing the exhaust gases in an exhaust gas scrubber and supplying wash water effluent exiting from the scrubber and containing impurities to a purification unit onboard a ship. In order for the method to purify wash water exiting the scrubber sufficiently enough to be discharged directly to sea, the purification unit includes a moving filter band, whereby an aqueous fluid containing impurities originating from the effluent is together with a precipitating agent fed to a surface of the inclined filter band and filtered there through to concentrate impurities onto the surface of the band filter as a precipitate. When necessary, the pH of the purified effluent is adjusted so that it is at least 6.5 before discharging the purified effluent into the sea or returning it to the exhaust gas scrubber.

  • Patent number: 9328541
    Abstract: A locking arrangement is arranged to lock together a first side and a second side that are at an angle to each other. On the first side, there is a locking member with a bar (6) and a transverse part. On the second side, there is at least one lug (5) and the transverse part (4) is settable to a locked position on the lug (5) on the second side and releasable from the locked position on the lug (5). The lug (5) on the second side is turnable away from beneath the transverse part (4) in the locked position and lockable to remain under the transverse part in the locked position.

  • Patent number: 8388285
    Abstract: A support arrangement for supporting load in a transportation unit, includes a rod-like support member placed beside the load to support it and two parallel rails in the longitudinal direction of the transportation unit and at a distance from each other. The support member includes support ends for fastening to support points in the transportation unit so that the support member is perpendicular to the longitudinal axis of the transportation unit. Safe and easily implemented support for the load to be transported is achieved by arranging the support member to move along the inner walls of the rails and guided by the inner walls to set it against the load. The support arrangement includes an elongated flexible member and a tightening element for tightening the elongated flexible member against the load so that displacement of the load in relation to the rod-like member is prevented.
