20090014138 | Production of Pulp Using a Gaseous Organic Agent as Heating and Reaction-Accelerating Media - The invention relates to an improved process to break down lignin macromolecules and liberating cellulose fibers in lignocellulosic material using delignifying reactants with a gaseous organic agent as a heating and reaction-accelerating media. Lignocellulosic material is first impregnated with reactant chemicals, e.g. commonly used agents such as sodium hydroxide and sodium sulfide. Subsequently, the energy required for the delignification reactions is provided through heating with a gaseous organic agent such as methanol or ethanol, condensing and releasing energy to the solid lignocellulosic material. The temperature during the heating step with a gaseous organic agent is higher than the temperature during the impregnation step. | 01-15-2009 |
20090218055 | Method for Recovering Hydrolysis Products - An improved method for treating lignocellulosic material, including a prehydrolysis-mass transfer process, which produces a concentrated hydrolysate volume during the time required for the hydrolysis itself. The improved process comprises the heating of the digester and chip content by direct steam to the required hydrolysis temperature, starting a flow of hot, stored hydrolysate to the top of the chip bed in order to create a trickle-bed type down-flow of hydrolysate, collecting a first fraction of the trickled-down hydrolysate as a product fraction, adding extraction liquid and continuing the trickle flow to collect a second hydrolysate fraction, which will be discharged from the digester to a hot hydrolysate storage tank to be used as the first trickle flow liquid in the next batch. | 09-03-2009 |
20090242152 | BLEACHING PROCESS OF CHEMICAL PULP - A process for the bleaching of chemical pulp, wherein the initial bleaching of the pulp includes a first chlorine dioxide treatment (D0) and a following alkaline treatment with oxygen and hydrogen peroxide (EOP), which stages are separated from each other with a washing stage, and a treatment of the pulp to reduce the content of transition metals of the pulp prior to the peroxide treatment. The process is characterized in that alkali is added to the pulp after addition of chlorine dioxide in the D0 stage to adjust the pH of the pulp to neutral or basic (N stage) prior to the washing stage following the chlorine dioxide stage, whereby the initial bleaching includes the sequence D0N EOP. | 10-01-2009 |
20090277596 | BLEACHING PROCESS OF CHEMICAL PULP - A process for the bleaching of chemical pulp, comprising a first chlorine dioxide treatment (D) of the initial bleaching and chelation (Q) to be carried out in connection therewith, forming together a DQ treatment. The process is characterized in that the chelation is carried out at the pH of from 2 to 7, and it is followed by an alkalizing stage (N) of the pulp, without intermediate washing for raising the pH of the pulp to above 7 and at most to 12 prior to a following stage which is a washing step. | 11-12-2009 |

20100224335 | HEAT RECOVERY FROM SPENT COOKING LIQUOR IN A DIGESTER PLANT OF A CHEMICAL PULP MILL - A method for heating white liquor or a mixture of white liquor and another liquid for use in a digester system of a chemical pulp mill, the method including the steps of: producing black liquor in the digester system; extracting black liquor from the digester system, flashing the extracted black liquor and thereby generating flashed black liquor and flash vapor; directing the flash vapor through a heat exchanger to heat a white liquor flowing through the heat exchanger; the flashed black liquor flows to at least one of a heat recovery or evaporation stage, and the heated white liquor flows to the digester system. | 09-09-2010 |
20100236733 | METHOD AND SYSTEM TO GENERATE STEAM IN A DIGESTER PLANT OF A CHEMICAL PULP MILL - A method for generating steam in a digester plant of a chemical pulp mill including: producing black liquor in the digester plant, extracting a first stream of black liquor from the digester; generating vapor by evaporating the first stream of black liquor by heating the first stream with fresh steam; heating fibrous material in the digester with the generated vapor from the evaporated first stream of black liquor; extracting a second stream of black liquor from the digester; flashing the second stream of black liquor to generate flashed black liquor and flashed black liquor vapor; introducing the flashed black liquor vapor to at least one heat exchanger to indirectly heat a clean evaporable liquid to produce clean steam from the clean evaporable liquid; and steaming, with the clean steam produced in the at least one heat ex-changer, cellulosic feed material before feeding the cellulosic feed material to the digester plant. | 09-23-2010 |
