摘要： A method for impregnation and chemical digestion of lignocellulosic material and recovery of pulping liquors. A spent impregnating or cooking liquor is withdrawn and sulphurous compounds are recovered therefrom in a partial oxidation reactor. These sulphurous compounds are converted into hot liquid elemental sulphur which thereafter is mixed with a hot sulphide containing liquor to provide a polysulphide liquor with a concentration greater than 10 g/l and which is essentially free from thiosulphate. This polysulphide liquor is used for carbohydrate stabilising impregnation and/or for cooking at a relatively low temperature.

摘要： The invention relates to a process for evaporating spent liquor or other waste liquids from cellulose cooking. The evaporation is performed in a multiplicity of evaporators which are coupled in series and in which the evaporation is driven using liquor steam. The condensates from the steam are divided, in one or more effects, into at least two fractions with respect to purity. The invention is characterized in that the purer fraction from one effect is conveyed, at a high level, into a subsequent effect in the direction of movement of the liquor, while the dirtier fraction is conveyed, at a high level or at the very top, into a preceding effect in the direction of movement of the liquor.

摘要： An apparatus for introducing a low concentration, high-volume non-condensable gas into a chemical recovery furnace comprising: a plurality of gas inlet pipes, which inlet pipes are connected to a source of said low concentration, high volume non-condensable gas and are vented to said chemical recovery furnace. A preheater is positioned in close proximity to said inlet pipes upstream the recovery furnace. The inlet pipes are coaxially enclosed by secondary air ports. The area of the secondary air ports are greater than the area of the inlet pipes.

摘要： Off gases (11) from black liquor heat treatment (10) evaporators, wood pulp digesters, etc. are treated to produce primarily hydrogen sulfide and sulfur free fuel gases such as methane, carbon monoxide, hydrogen, and ethylene. Then the hydrogen sulfide is used to produce sodium polysulfide in white liquor for cooking wood chips to produce pulp by the kraft process. Polysulfide may be formed in three different ways: by supplying air to a fuel cell (15) into which white liquor and the hydrogen sulfide containing gas have been introduced; by bringing clarified white liquor and hydrogen sulfide containing gas into contact with a wet-proofed activated carbon catalyst and oxygen containing gas; or by bringing unclarified white liquor into contact with the gas and oxygen containing gas, with lime mud acting as a catalyst, and then clarifying the polysulfide-rich white liquor produced to remove the lime mud. The white liquor produced contains about 0.5-8% on wood sodium polysulfide.

摘要： Procédé et dispositif de séparation et d'épuration d'un gaz, notamment le gaz restant après la délignification par ozone ou la suspension de pâte, à partir d'une suspension fibreuse. On introduit la suspension et le gaz dans un cyclone (2) dans lequel se produit la séparation essentielle de la suspension, puis on évacue vers le bas la suspension essentiellement exempte de gaz, et on évacue vers le haut le gaz (5) contenant des fibres résiduelles et/ou d'autres impuretés. Avant son évacuation, le gaz en écoulement (5) traverse un bain de liquide destiné à en séparer les fibres résiduelles et/ou les autres impuretés.

摘要： Method of activating aqueous lignocellulosic material with a gas containing nitrogen oxide, followed by a delignification stage for the purpose of obtaining a high quality end product with no or only a slight effect on the environment. In accordance with the inventive method, the lignocellulosic material is brought into contact (18) with an oxygen-containing gas (19), and activating gas is separated from the lignocellulosic material during and/or subsequent to the activating process (9). The method is characterized by a) controlling the supply of oxygen-containing gas (12) such that the separated gas (27) contains at least 2 kg nitric oxide (NO) calculated on 1000 kg of dry lignocellulosic material, and by b) reacting the separated gas (27) in one or more stages (26) with absorption solution (25) whose original pH lies within the range 3-13.5, and by passing (28) the gas purified with the aid of absorption solution to atmosphere, or to a destruction plant optionally subsequent ot further purification of the gas.

摘要： The present invention solves the problems encountered when charging oxygen (0 2 ) to and removing inert gas from the reactor gas obtained in the activation of lignocellulosic material with gas that contains nitrogen dioxide (N0 2 ) and subsequent delignification of the material, the material being preferably in the form of chemical, aqueous cellulose pulp. The invention resides in a method which is characterized by separating (5) gas rich in nitrogen oxides from the lignocellulosic material during and/or after the activation thereof; by treating (6) all or part of the separated gas rich in nitrogen oxides with oxygen (7) in an amount corresponding to 10-200 mole percent calculated on the amount of nitric oxide (NO) present in the gas rich in nitrogen oxides separated for this treatment; by bringing (8) oxygen-treated gas into contact with lignocellulosic material so as to activate the material; and by separating gas lean in nitrogen oxides from the lignocellulosic material during a stage of the activation process different to that from which gas rich in nitrogen oxides was taken; and by removing (9) gas lean in nitrogen oxides from the process.
