摘要： The method is for the production of cellulose pulp in a continuous digester system. Chips are impregnated in an impregnation vessel. The chips are then fed to a subsequent digester vessel in a transfer fluid. A black liquor withdrawal is taken from the digester, which withdrawal is led to the bottom to heat the chips before the chips are fed out from the impregnation vessel. A transfer fluid is withdrawn from the digester and led to the impregnation vessel to act as an impregnation fluid. At least a portion of the transfer fluid that was withdrawn from the top of the digester passes an indirect heat exchanger, in which the transfer fluid withdrawn from the top of the digester at a temperature of at least 125° C. exchanges heat indirectly with a first fluid for the production of steam from the first fluid.

摘要： A procedure for arranging water circulations in an integrated paper mill, the paper making process of which having three partly separate process phases concerning the water circulations (I, II, III). In the first phase, the fiber raw material is pretreated, defibered and cleaned for producing mechanical, chemi-mechanical and recycled pulp, in the second phase the pulp is treated further for improving the quality, and in the third phase it is made into paper or board. The circulation waters of the first process phase are concentrated by circulating the filtrates of the concentration and pressing phases counter-current inside the water circulation (I), and the circulation water thus concentrated is conducted into an effluent evaporation plant to be concentrated and then burnt in a combustion boiler. The water quantity discharged from the water circulation (I) of the first process phase is replaced by conducting such circulation waters of the paper mill into the front dilution of the press.

摘要： Kraft pulp of increased strength and bleachability may be produced with decreased consumption of effective alkali, and at a lower H factor, by keeping the dissolved organic material (DOM) concentration low substantially through the entire kraft cook, including by extracting high DOM liquid from at least one part of a continuous digester and replacing it with much lower level DOM liquid. Existing pulp mills having two-vessel hydraulic, one-vessel hydraulic, or other systems may be retrofit to provide for extractions and additions of low DOM dilution liquor (including substantially DOM-free white liquor). Also, commercial size batch digesters (8 tons per day of pulp or more) can be operated with low DOM liquor to produce increased strength pulp. Using dilution with low DOM liquor also results in reduced H factor and effective alkali consumption, and increased bleachability.

摘要： This invention is related to a process for producing pulp from a cellulosic starting material, wherein an aqueous process effluent is purified from metal impurity cations. This process comprises that the effluent is purified by an electro-chemical membrane treatment in an electrochemical membrane device comprising a unit cell through which an electric current is passed between an anode side and a cathode side of said cell, said cell comprising at least two ion permeable membranes forming between them at least one compartment, said effluent being fed into an effluent feed compartment in said cell, in which the effluent is purified by removing with the electric current metal impurity cations from the effluent through a cation selective membrane on the cathode side of said compartment, and withdrawing from said compartment the purified effluent. The purified effluent may be recirculated to the pulp mill process, e.g. as washing water.

摘要： Apparatus for a pulp and paper mill, and methods of acting on liquid effluents produced in the mill, which minimizes the discharge of polluting gaseous and liquid effluents to the environment. Liquid effluents from the bleach plant are concentrated (e.g. evaporated), incinerated (e.g. gasified), leached, crystallized (e.g. freeze crystallized) then washed, and then fed to the plant chemical recovery loop. White liquor produced from the recovery boiler melt is fully oxidized and used in place of caustic in the bleach plant. Essentially all sulfuric acid, sulfur dioxide, caustic, and chlorine dioxide necessary for the pulp mill is produced from mill liquid effluents and gas waste streams, on site at the pulp mill. Typical bleaching sequences that can be used are DE.sub.op D.sub.n D, or AZE.sub.o PZP.

摘要： Digester systems for producing paper pulp from comminuted cellulosic fibrous material take into account the level of dissolved organic materials (DOM), such as lignin, hemi-cellulose, and cellulose, maintaining the DOM level at about 100 g/l throughout the cook (particularly kraft cook). In order to make sure there is sufficient liquid to slurry the material in the feed system of a two vessel system, some liquid is withdrawn from the circulation conduits between the digester and impregnation vessel, cooled, and fed to the feed system. In a vapor phase digester, the level of liquid at the top of the digester is more precisely controlled by circulating some of the withdrawn liquid from a circulatory loop of the digester to the level tank associated with the feed system. An in-line drainer may be provided in the feed system between a make-up liquor pump and a liquid inlet conduit leading to the top of an impregnation vessel. Within the digester, a set of extraction/dilution screens is provided specifically positioned and spaced from each other, and with respect to a reintroduction conduit opening, so that mixing of different DOM concentration liquids is minimized.

摘要： A conventional continuous digester is modified so as to provide a countercurrent cook throughout the entire height of the digester. Instead of connecting an upper mid-point extraction screen to a flash tank, that screen is closed off and extraction is provided at the top of the digester, utilizing an in-line drainer to remove some of the liquor and feed it to a flash tank. The liquor not removed recirculates through a pressure screen to an impregnation vessel, and then back to the digester. A cooling circulation is provided just below the top extraction. Valves are provided in the liquor discharged from the drainer and a conduit from the upper mid-point extraction which may be manipulated to return the digester to conventional operation, including the addition of white liquor to the bottom recirculation.
