Abstract: A scrubber system for treating exhaust gas in a marine vessel with a water based solution includes a first scrubber unit and a second scrubber unit, an exhaust gas inlet in the first scrubber unit and an exhaust gas outlet in the second scrubber unit and a second conduit section connecting the first scrubber unit to the second scrubber unit, a first scrubbing medium circuit and a second scrubbing medium circuit. The first scrubber medium circuit is provided with a source of scrubbing solution having a first connection to an outside of a hull of the vessel beneath the water line of the vessel and the second scrubber medium circuit is provided with a source of scrubbing solution having a source of fresh water in the vessel.

Abstract: The invention relates to a scrubber unit arrangement for cleaning exhaust gas. The arrangement comprises a scrubber unit for receiving a flow of exhaust gas, a pump means for supplying a scrubbing medium to the scrubber unit from a source of scrubbing medium, and means for discharging scrubbing medium from the scrubber unit. In order to provide an energy efficient scrubbing process, the scrubber unit arrangement further comprises a turbine unit, which is arranged to receive discharged scrubbing medium from the scrubber unit. Scrubbed exhaust gas is separately discharged from the scrubber unit.

Abstract: An exhaust gas receiver that is connectable to an internal combustion engine for receiving exhaust gases from the engine, the exhaust gas receiver comprising a receiver chamber, at least one exhaust inlet, at least one exhaust outlet, and a reducing agent duct, at least a portion of the reducing agent duct being arranged inside the receiver chamber for heating the reducing agent before the reducing agent is mixed with the exhaust gases. The invention also concerns an internal combustion engine and a method for selective catalytic reduction.

Abstract: Procedure and apparatus for controlling the barking process in a barking drum, which procedure uses measuring devices (13a,13b,14a,14b) placed in conjunction with the barking drum (1) to measure the weight of the drum. The measurement signals obtained from the weight measuring devices are used to calculate the degree of fullness of the drum, and this data is used to control the position of the delivery gate of the drum so as to achieve the desired degree of fullness. Moreover, the degree of barking of the logs is monitored, and the barking degree data is used as a basis for the control of the speed of rotation of the drum.
