The present disclosure describes a system for predicting explosions in a dissolving tank. The system includes acoustic emission sensors placed in or around the dissolving tank. By filtering the recorded frequencies to the range which is most sensitive for desired explosions fingerprints, it is possible to predict a smelt influx before the smelt influx occurs as well as program response actions to prevent compromising explosions.


Method for determining chipper machine wear part replacement needs using cutting impact force, bearing temperature, and vibration information.


The present invention relates to a method of producing steam at a digester plant of a chemical pulp mill. Black liquor is discharged from the digester (17) at a first temperature and pressure. The black liquor is treated in a flash tank (34) for generating flashed black liquor and flash steam at a second temperature and a second pressure, which are lower than the first temperature and pressure. The flashed black liquor (35) is taken for further treatment to the evaporation plant. The flash steam (38) is led to an indirect heat exchange contact with clean liquid in the reboiler (39) for boiling the liquid and for generating steam. The steam is led from the reboiler (39) into a fan or compressor (41) for increasing the steam pressure to a third pressure, which is higher than the second pressure and for adjusting the pressure of the steam in the flash tank. Steam at a third pressure is used for pretreating comminuted cellulosic fiber material, such as chips, prior to cooking.

The invention relates to a film-stretching machine comprising two tracks, each one having a first rail (1) whereon clamps (3) move, said clamps closing at a set point of the pitch thereof, and a second rail (2) whereon carriages (5) move, said carriages being articulated, in a chain driven by a driving toothed wheel (6), in relation to two consecutive clamps, characterised by a wheel for indexing the set point of the pitch of the clamps.


A refining system and process using a specially designed stator refiner plate. The specially designed stator refiner plate includes a major refining surface having a series of bars and grooves, the bars include a leading surface having an irregular surface. The irregular surface hosts a series of protrusions extending along the bar. The bar further comprises a trailing surface that is relatively smooth compared to the leading surface. The trailing surface lacks an irregular surface.


A cast metal plate segment for a refiner of lignocellulosic material or a disperser of comminuted paper or packaging products, the plate segment including a front side with a front surface configured to refine the lignocellulosic material or disperge the comminuted paper or packaging products, and a back side, opposite to the front side, including a corner or edge, wherein the corner or edge comprises a casted surface between machined planar surfaces adjacent the corner or edge.

A Francis turbine runner including a shortened band length and a shortened blade length combined with a reversed runner blade leading edge having a junction of the leading edge with the band forerunning a junction of the leading edge with the crown in the rotational direction, and a bandless runner including a shortened periphery length and a shortened blade length combined with a reversed runner blade leading edge having a corner of the leading edge at the outer periphery of the runner that is in advance of where the leading edge joins the crown in the rotational direction. Additional feature includes an inverted trailing edge curvature design on the runner blade that further shortens the blade length.

The main objective of NeoCel project is to develop innovative and techno-economically feasible alkaline processes enabling the sustainable production of higher quality eco-innovative textile fibres from reactive high-cellulose pulps and integration of these processes with pulp mills. Targets for the development of NeoCel processes are: - wet strength of fibres higher than the wet strength of standard viscose, competing with cotton properties. - lower environmental impact than any other type of existing textile fibre - Reduction of production cost by at least 15% compared to that of best available technology (BAT) viscose The targets will be met through development of adapted pulps with high reactivity/solubility in alkaline water-based solutions, advanced dissolution process to maximize cellulose concentration, novel cellulose regeneration chemistry enabling both recovery of process chemicals and increased strength properties of the spun fibre, design for integration of textile fibre production with the pulp mill for minimized environmental impact, increased energy efficiency and reduced chemical consumption through system analysis using software models of theoretical mills. In NeoCel, a consortium with raw material processing companies, chemical suppliers, equipment producers, SMEs and world-leading research institutes has formed to develop the processes for large scale manufacturing of eco-innovative textile fibres. The consortium expects that a successful NeoCel project will enable creation of 75 000 new jobs and a turn-over increase of 9.5 billion for European forest products, textile and clothing industries within 15 years. However, already within 3 years, the consortium partners expect their joint turnover to increase by 170 MEuro
