Abstract: A method for pulp delignification/bleaching with peroxide comprising a treatment step with chelating agents in order to free the pulp from disturbing metal ions. Disturbing metal ions are deactivated by separating a liquid phase from the pulp after the treatment with chelating agents and the separated liquid phase containing chelating agents is treated with oxidizing agents such as ozone or peroxide. The liquid phase treated accordingly, preferably with peroxide, is returned to the pulp which in a subsequent step is subjected to a bleaching step with peroxide.

Abstract: A method of oxygen delignification of chemical pulp in two stages. The first stage is carried out in an upstream reactor vessel (3), in which a pressure exceeding 3 bar is maintained. The second stage is carried out in a downstream reactor vessel (4), in which the temperature is between 90 and 120 DEG C and where the pressure is adapted to the temperature. Heating of the pulp is carried out between the stages by means of low pressure steam.

Abstract: In a method of pre-pressing a formed web of finely-divided lignocellulosic fibre material prior to pressing the web to a finished state in the continuous manufacture of board material, the fibre material is compacted and pressed successively in an entry section (7) of a pre-press (6) subsequent to being formed into a web (11) and subsequent to a first compression and expansion. The web is compressed in this latter pressing process to a density close to the density of the web after the first compression, whereafter the web is allowed to expand to a controlled limited extent in a pre-press expansion section (9), and thereafter transferred to the finishing press. Steam (A, B) is injected into the web (9) when the web is located in the pre-press (6).
