Abstract (en)
[origin: EP1944410A1] The method involves delivering a fibrous suspension (S) using material pumps (9, 10) by pressure increased for a process step. A part of the fibrous suspension subjected to increased pressure is derived as branch currents (19, 20) and is reduced to another pressure that is suitable for another process step. The latter pressure is reduced by turbines (5, 6), which uses mechanical power output that occurs during the pressure reduction. The mechanical power output is converted into electric current and is used for mechanical operation of rotors of the pumps.
