摘要： The present invention relates to a method of producing steam at a digester plant of a chemical pulp mill. Black liquor is discharged from the digester (17) at a first temperature and pressure. The black liquor is treated in a flash tank (34) for generating flashed black liquor and flash steam at a second temperature and a second pressure, which are lower than the first temperature and pressure. The flashed black liquor (35) is taken for further treatment to the evaporation plant. The flash steam (38) is led to an indirect heat exchange contact with clean liquid in the reboiler (39) for boiling the liquid and for generating steam. The steam is led from the reboiler (39) into a fan or compressor (41) for increasing the steam pressure to a third pressure, which is higher than the second pressure and for adjusting the pressure of the steam in the flash tank. Steam at a third pressure is used for pretreating comminuted cellulosic fiber material, such as chips, prior to cooking.

摘要： The present invention relates to a method and an arrangement for treating chemical pulp that has been cooked to a high kappa number. Pulp 'is produced by cooking in an alkaline cooking process to a kappa number of 50-120, preferably 60-100, the cooked pulp is washed, the washed pulp is led into an oxygen stage where the pulp is treated in the presence of oxygen and alkali for removing lignin, and the oxygen-treated pulp is washed, whereby lignin-containing washing filtrate is formed. In the oxygen stage the kappa number of the pulp decreases by at least 30 units. The filtrate downstream of the oxygen stage is treated for separating lignin, and the treated filtrate is led as washing liquid into the washing apparatus for the cooked pulp.

摘要： The present invention relates to a method of producing chemical pulp at a con¬ tinuous digester plant. The method comprises the following steps: a) leading a slurry formed of comminuted cellulosic fibrous material and liquid into a digester and treating the material with a treatment chemical at a temperature over 130 °C for producing treated material and black liquor; b) extracting at least one black liquor stream from the digester and leading the black liquor into an indirect heat exchange relationship with steam in a heat ex¬ changer for heating the black liquor; c) leading the heated black liquor into a flashing vessel, wherein flash steam and flashed black liquor are generated, and d) using flash steam from step c) for heating the fibrous material in the digester in step a).

摘要： The field concerned is NFC or MFC production using chemical pulping. Herein is provided an environmentally friendly and improved pulping and papermaking method and dissolution and digestion method of cellulosic mate- rial. It is especially useful for treating chemical pulps. Consequently, improved products from these processes are provided. This improvement is achieved by changing the fiber structure in the pulping. Pulps may contain any type of cellulosic fibers, including wood and non-wood fibers.

摘要： The present invention relates to an arrangement and method for separating harmful material, especially sand, from a liquid stream or a low-consistency fibre suspension in a pulp production process. The arrangement comprises a cyclone-type separator comprising a vertical chamber, in the upper part of which a tangential inlet is arranged for creating a swirling motion for the stream to be cleaned, and an accept outlet, the conical lower part of which separator is provided with a reject outlet. The arrangement comprises two or more cyclone-type separators (301) that are connected in parallel, whereby their inlets open into at least one feed channel (310) having at least one inlet, and their accept outlet open into a common discharge channel (313) having at least one outlet, and their reject outlets open into a common discharge channel having at least one outlet that is connected to at least one auxiliary separator (316) having conduits (318, 319 ) for discharge of accept and reject.
