20100276094 | Apparatus For Washing And Dewatering Pulp, A System For Controlling Such An Apparatus, And A Method For Processing Pulp In Such An Apparatus - Methods for processing pulp in an apparatus for washing and dewatering pulp and a system for controlling this apparatus are provided. The apparatus includes a pair of rotatable press rolls installed in vats and including a press nip therebetween, an inlet for feeding the pulp to the press nip, with one of the press rolls being movable in relation to the other and in which the processing of the pulp is determined by the number of variable operating parameters. The method includes utilizing the distance between the press rolls as a variable operating parameter, setting a desired value for a specific control parameter, measuring the specific control parameter, and adjusting at least two of the variable operating parameters during operation to maintain the difference between the desired value and the measured value of the specific control parameter below a predetermined difference. Systems for controlling this apparatus are also disclosed. | 11-04-2010 |
20110253327 | METHOD FOR REFINING CELLULOSE FIBERS IN AQUEOUS SUSPENSION AS WELL AS REFINER FILLING TO IMPLEMENT SAID METHOD - The invention relates to a method for refining cellulose fibers in aqueous suspension, using a plurality of refiner fillings having refining edges, of which one is operated on at least one stator and another is operated on at least one rotor, and the suspension to be refined is processed between the two refiner fillings. A partial flow of the suspension delivered to the outlet side flows back on the back side of the refiner filling on the stator side, and then flows through openings located between the refining edges of the refiner filling on the stator side, and again into the refining zone. This leads to particularly uniform and economical refining. | 10-20-2011 |
20120138246 | Method and apparatus for conversion of cellulosic material to ethanol - The present invention provides an apparatus and a method for conversion of cellulosic material, such as chopped straw and corn stover, and household waste, to ethanol and other products. The cellulosic material is subjected to continuous hydrothermal pre-treatment without addition of chemicals, and a liquid and a fibre fraction are produced. The fibre fraction is subjected to enzymatic liquefaction and saccharification. The method of the present invention comprises:

20130192775 | WASHER PRESS WITH MULTIPLE NIPS AND MULTIPLE DISPLACEMENT WASH ZONES AND METHOD - A washer press apparatus for washing and dewatering a wide range of solids concentrations of pulp in liquid suspensions includes multiple distinct displacement wash zones about a drum with multiple nips. | 08-01-2013 |
20140231034 | ENZYMATIC PRETREATMENT OF WOOD IN A METHOD FOR PRODUCING MECHANICAL PAPER PULP - A method for producing mechanical paper pulp comprises: impregnating unprocessed wood, whereby unprocessed wood is exposed to an impregnating composition comprising at least a laccase enzyme and a formula mediator (I), wherein R | 08-21-2014 |
20150007952 | METHOD FOR PRODUCING A CELLULOSE SUSPENSION - The present invention relates to the preparation of a cellulose suspension, particularly of a premixture for the preparation of a cellulose suspension in organic solvents such as an aqueous N-methylmorpholine N-oxide (NMMO) solution. | 01-08-2015 |
20160097157 | System and Method Using a Reaction Chamber to Beneficiate Organic-Carbon-Containing Feedstock for Downstream Processes - Systems and methods for producing processed organic-carbon-containing feedstock from an unprocessed carbon-containing feedstock are described. Unprocessed feedstock is introduced into and transported through at least one reaction chamber. The reaction chamber is configured for each feedstock to produce processed feedstock having a water-soluble salt reduction of at least 60 percent from that of unprocessed organic-carbon-containing feedstock and a water content of less than 20 percent. | 04-07-2016 |
