摘要： The method is for the preparation of kraft pulp with increased pulping yield from lignin-containing cellulosic material using polysulfide cooking liquor. In order to increase carbohydrate stabilization and hence the yield from a kraft cooking process a first impregnation stage is using polysulfide cooking liquor implemented at high alkali and polysulfide concentration and at a low temperature.

摘要： An arrangement for feeding and dewatering lignocellulosic material in a hydrolysis process between a first reactor unit, where the material is partly hydrolyzed, to a second reactor unit, wherein the first reactor unit operates at a first pressure and the second reactor unit operates at a second pressure being higher than the first pressure. The arrangement includes a first plug screw feeder arranged to receive the partly hydrolyzed material from the first reactor unit and being arranged to compress, dewater and transport the material, wherein the first screw feeder is arranged to operate at a pressure being higher than the first pressure. A dilution vessel is coupled to receive material from the first plug screw feeder and including a liquid inlet for receiving liquid to wash the material, wherein the dilution vessel is arranged to maintain or increase the pressure (PDM). A second plug screw feeder is arranged to receive the diluted material and to compress, dewater and transport the material to the second reactor unit, wherein the second screw feeder is arranged to operate at a pressure being higher than the pressure of the first plug screw feeder. A system including such an arrangement and a first reactor unit and a second reactor unit is also presented.

摘要： The invention relates to a reel-up 3 for receiving and winding into a roll 4 a paper web W that arrives from a drying cylinder 2 in a paper making machine and which drying cylinder 2 is located upstream of the reel-up 3 and which paper web W follows a path of travel from the drying cylinder 2 to the reel-up 3. The reel-up 3 comprises a rotatably mounted reel spool 5 onto which a paper web W can be wound to create a paper roll 4 of increasing diameter and an endless flexible belt 6 mounted for rotation along a predetermined path of travel such that the flexible belt 6 forms a loop. The flexible belt 6 is positioned adjacent to the reel spool 5 to engage the paper web W against the reel spool 5 during winding. The reel-up 3 is arranged to receive the paper web W at the end of a path of travel of the paper web W which ends in a point of contact P with the flexible belt 6 where the paper web W meets the flexible belt 6 such that a wedge-shaped space WS is formed between the flexible belt 6 and the paper web W. From the point of contact P, the paper web W will be carried by the flexible belt 6 to the reel-spool 5. According to the invention, the reel-up 3 further comprises an air deflector 8 for diverting or evacuating air away from the wedge-shaped space WS formed between the flexible belt 6 and the paper web W. The invention also relates to a method of reeling a paper web.

摘要： The method is for separation of lignin from original black liquor (BLIN) that has a first precipitation phase (PR1/PR2) for precipitation of lignin by a first acidification using acidifier, CO2, at alkaline conditions, then separating a lignin cake with subsequent suspension of the lignin cake in a strong acid in order to leach out metals from the lignin followed by dewatering and obtaining a clean lignin product LP. Lignin germ particles (LG) are added to the original black liquor in the first precipitation stage, preferably between two phases in said precipitation stage, in order to increase lignin particle growth on such lignin germ particles instead of spontaneous nucleation of lignin particles in said original black liquor. This results in improved filterability in subsequent dewatering and lignin cake formation and hence an increased lignin yield.
