Abstract (en)
[origin: EP2085509A2] A method and system for determining chip pressure in a vessel (10) containing a slurry of lignocellulosic material including: sensing a total static pressure of the slurry in the vessel (10); sensing a hydrostatic pressure of the liquor in the vessel (10), and determining the chip pressure based on a difference of the sensed total static pressure of the slurry and the sensed hydrostatic pressure of the liquor.
