摘要： The method is for pre-treatment 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 is established within the chip pieces. When the chips are subsequently formed into slurry with preferably a sulphide-rich alkali cooking fluid, H2S is formed locally in the chip pieces which gives a yield-increasing effect in the subsequent cooking step of 1-3%.

摘要： The arrangement and method for the steam pre-treatment of chips during the production of cellulose pulp avoids the blow-through of gases in the steam pre-treatment vessel. This prevents foul-smelling gases from being released into the atmosphere. The inlet of the vessel has an inclined feeder device in a feeder-housing. In the event of the initiation of the risk for blow-through of steam, the feeder housing is sprayed with cooling liquid in order to increase condensation capacity of the chips being fed into the vessel. Ultimately the feeder housing is filled with liquid that establishes a liquid lock, and preferably at the same time as the feeder drive (M) is shut off. This avoids the emission of gases from the chip bin when interruptions in the process occur so that the release of odors into the surroundings is minimized.

摘要： The cyclone is for separating gas from a gas laden liquid stream by pressure reduction of the liquid stream. The cyclone has a cylindrical casing, having a tangentially directed inlet arrangement for the gas laden liquid stream, a lower outlet line for liquid and an upper outlet line for vapor and gas. The inlet arrangement is connected to a common supply source (BLPR), and has at least two insertion pipes. The flow in at least one of these insertion pipes is controlled by at least one valve that depends upon an order of flow from the common supply source to maintain a flow velocity above a critical value.

摘要： The invention concerns a method for the production of cellulose pulp. A wood raw material that principally comprises softwood, preferably in the form of cut wood chips, is treated in several stages in various treatment steps. One of the stages is cooking the material in an alkali cooking fluid, with the aim of obtaining improved quality with respect to tensile strength, and of obtaining higher yield. A controlled addition of wood raw material in the form of hardwood at an amount corresponding to 1-20% of the amount of softwood, preferably 3-15%, and more preferably at least 5%, takes place.

摘要： The method is for the pre-treatment 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, H2S is formed locally in the chips, which gives a yield-increasing effect for the subsequent cooking step of l-3%.

摘要： The continuous digester is for producing pulp from comminuted cellulosic material. The digester has a cone diverter on a bottom scraper arranged in the bottom of the digester for assisting in out feed of pulp produced. The cone diverter of the bottom scraper has an upper inclined surface of the cone diverter with an inclination angle in the range 30±10 degrees in relation to the vertical. In order to improve washing performance in the bottom of the digester, especially for overloaded digesters, the upper inclined surface is equipped with draining apertures in fluid communication with a liquid receiving chamber inside the cone diverter. The liquid receiving chamber is connected via a drainage channel to the exterior of the vessel.
