摘要： The invention concerns improved ventilation of strainer packages in diffusers used for diffusion washing of cellulose pulp. The strainer packages in the diffuser are provided with exhaust air tubes 30/30a-30f that discharge built-up gas accumulations from inside the strainer to a position in the diffuser at lower pressure. This discharge means that discharged gases do not disrupt the subsequent washing cycle and that the washing efficiency of the diffuser can be kept high even at process locations where large amounts of gas are produced in the to pulp.

摘要： A method for feeding a chips slurry from a low- to a high-pressure system during the continuous cooking of chemical cellulose pulp. The feed takes place through a sluice feeder (53') between these systems. The sluice feeder is provided with a rotor with through-pockets (1, 2) that are alternately connected with the low- or the high-pressure system. A recirculation line (54') comprising a high-pressure pump (57') extends from the first outlet (53b') of the sluice feeder to the second inlet (53c') of the sluice feeder for transport of the fluid that has been expelled from the pockets of the sluice feeder when these are located in their first position. The fluid that according to the method expels the chips mixture from the pockets of the sluice feeder in their second position is essentially exclusively constituted by the fluid that has been expelled from the pockets in their first position.

摘要： The invention concerns a method for the pretreatment of chips that are fed to a sulphate cooking process. Through the addition of an acidic fluid to the steam treatment step, a very high ionic concentration of hydrogen ions is achieved. When the chips are subsequently formed into a slurry with a preferably sulphide-rich alkali cooking fluid, H 2 S is formed locally in the chips, which gives a yield-increasing effect for the subsequent cooking step of 1-3%.

摘要： The invention concerns a method for the pretreatment of chips that are fed to a sulphate cooking process. Through acidification of the chips in an acidic treatment fluid with a subsequent draining of free treatment fluid before subsequent steaming or wet-steaming, a high concentration of free hydrogen ions can be established within the chip pieces. When the chips are subsequently formed into a slurry with preferably a sulphide-rich alkali cooking fluid, H 2 S is formed locally in the chip pieces, which gives a yield-increasing effect in the subsequent cooking step of 1-3%.

摘要： The invention concerns a method for the continuous cooking of pulp and a digester. At least two withdrawal positions (11E, 11D) for cooking fluid are arranged at different heights in the digester (10). The cooking fluid in the first and second position is withdrawn after the chips has had a retention time that differs by at least 10 minutes, preferably at least 20 minutes. The differential pressure between the positions is determined and when this exceeds a pre-determined level, a connection (17E) opens between these positions, establishing a flow parallel to a flow of cooking fluid between these positions in the digester. Several withdrawal positions are preferably connected in a common shunt system (17A-17F), with values (18A-18F), controlled by the differential pressure, located between adjacent positions. The system allows increases in production capacity, washing efficiency and level of operation, with reduced risk for pulp hanging and channelling.

摘要： The invention relates to a feed arrangement for feeding chips to chip bins (1) in the production of cellulose pulp in continuous digesters (16), in which the chip bin is constituted by a greatment vessel having a top and a bottom, in which the chips are fed into the top (13) of the treatment vessel and fed out via the bottom of the treatment vessel using suitable lock members (10, 11). Distribution devices (4a, 4b) for the addition of steam are disposed in the treatment vessel so as to heat the chips to a level above 80 °C, preferably around 100 °C, when the chips are fed out via the bottom of the treatment vessel. By virtue of the fact that the chips are fed into the treatment vessel via at least one liquid lock (30) and the treatment vessel is otherwise sealed off, the quantity of driven-off gases from the chip bin is reduced to a minimum, at the same time as an effective utilization of available energy is obtained.
摘要翻译：本发明涉及一种用于在连续消化器（16）中生产纤维素纸浆中的芯片仓（1）中供给碎屑的进料装置，其中切屑仓由具有顶部和底部的升高容器构成，其中碎片进料到处理容器的顶部（13）中，并使用适当的锁定构件（10,11）经由处理容器的底部送出。用于加入蒸汽的分配装置（4a，4b）设置在处理容器中，以便当芯片通过处理的底部送出时将芯片加热至高于80℃，优选约100℃的水平船只。由于芯片经由至少一个液体锁（30）进料到处理容器中，并且处理容器被另外密封，所以来自切屑仓的排出气体的量减少到最小，在同时获得有效利用可用能量的同时。

摘要： The invention concerns an improved method to sluice chips from a low-pressure section to a high-pressure section with a sluice feeder 53" (a high-pressure feeder). The fluid that is used to expel the chips from the sluice feeder 53" principally comprises pressurised fluid withdrawn from the treatment vessel 60", which pressurised fluid is normally withdrawn from the treatment vessel 60" for recovery (REC). By using this pressurised fluid instead to expel the chips from the sluice feeder 53" and subsequently sending the previously pressurised fluid to the recovery system (REC), the requirement for high-pressure pumps that consume large quantities of electrical energy can be considerably reduced.

摘要： The invention concerns a method for the modification of cellulose fibres with the aim of increasing the strength properties of the pulp. Cellulose derivative, preferably in the form of CMC, is added in associated with alkali cooking and/or delignification of cellulose chips in a suspension with treatment fluid, in an amount exceeding 2 kg, preferably at least 5-7 kg, per tonne of cellulose. Addition of cellulose derivative to the suspension takes place when the suspension has a concentration of calcium released from the cellulose exceeding 20 mg/l. The conditions required for an efficient deposit of cellulose derivative onto the cellulose fibres can be established in this way, where the natural content of calcium in the wood raw material has been released and contributes to a high ionic strength, while an advantageous high temperature is established. No additional process stages re required and operating costs can be kept low.

摘要： The invention concerns an arrangement and a method for the continuous cooking of chemical cellulose pulp in a continuous digester system (100). The continuous digester system (100) comprises an inlet (102) for the feed of a chips suspension and an outlet (103) for the output of a cooked suspension of pulp. The suspension of chips is fed in to the inlet through a line (105) at the beginning of the cook, where the chips suspension has a volume of starting cooking fluid that establishes a fluid/wood ratio that is greater than 3.5. The invention is characterised in that a final cooking fluid is present during the cook for the major part of the cook and is withdrawn through a withdrawal strainer (106) only during the final 15 minutes of the cook. The final cooking fluid ensures a fluid/wood ratio that is greater than 3.5 in association with the withdrawal. The withdrawn final cooking fluid during the final 15 minutes of the cook consists of spent black liquor, which maintains a residual alkali level that lies under 15 g/l.
