Abstract: A method for washing sulphate cellulose pulp in the washing department of a sulphate cellulose mill, in which method a first pulp flow (1) is conducted to a first washer (101), where a washing liquid (12) is combined with the first pulp flow (I). A second pulp flow (2) is conducted from the first washer (101) to a second washer (102), where a washing liquid (3) is combined with the second pulp flow (2). The washed pulp flow (5) is proceeded from the second washer (102) in the process and the filtrate (4) displaced by the washing liquid (3) is recycled to the process so that the filtrate (4) displaced by the washing liquid (3) in the second washer (102) is divided into a first part flow (6) and a second part flow (7) and the pH of the second part flow (7) is dropped by combining an acidifier (8) with the second part flow (7). The acidified part flow (9) is conducted to a process unit (103), where sludge (10) containing extractives and metals is separated from the part flow (9) and the entire process and the part flow (11) treated in the process unit (103) is combined with the first part flow (6) and is recycled to the process for use as the washing liquid (12) in the first washer (101).

Abstract: The invention relates to a method and a display system for monitoring a grade shift in a paper or board machine. The monitoring is based on process parameters measured by sensors (9) in the process, the parameters being monitored centrally on a common display (12). In accordance with the invention, the display (12) comprises adjacent meters (13) equipped with rotating indicators (14), the indicators having a common base direction, such as, for instance, pointing straight upward, corresponding to a situational set value specified for each parameter. During the grade shift, the set values are gradually changed in accordance with the new paper or board grade. Consequently, any malfunctions or deviations from the expected shift process appear as a deviation of the indicator from the common base direction. By the same principle, the display can be used for monitoring a normal process state between grade shifts.

Abstract: The invention relates to a polymer-coated heat-sealable packaging material, its manufacturing method and a sealed package manufactured thereof. The material comprises a fibre base (3), which is a packaging paper or packaging board, an outer polymeric heat sealing layer (1, 8), which is, for example, LDPE, and an inner polymeric water vapour barrier layer (2, 7), which according to the invention is partly or totally formed of cycloolefin copolymer (COC). The COC water vapour barrier and the heat sealing layers are brought onto the fibre base by extrusion, and they can be placed on one side or on both sides of the fibre base for achieving a moisture barrier on both sides of the package. Also polymeric oxygen barrier layers, such as EVOH or polyamide layers can be incorporated in the packaging material. COC is amorphous, and by using it as an extruded water vapour barrier layer, curling of the packaging material is prevented. The packages according to the invention comprise carton, box and bag packages for dry and liquid foods.
