Abstract: The process is for continuously cooking chemical pulp in a digester system consisting of at least one vessel for impregnating and cooking comprising an inlet into which a mixture of chips and process liquid is fed. The chips are impregnated at a predetermined impregnation temperature, Timp, and cooked at a predetermined cooking temperature, Tcook, after which dissolved pulp is fed out at the outlet of the digester system. The process liquid which is continually extracted is retained outside the digester system during a dwell time, t, of at least 30 min, without any heating above 140°, and thereafter returned to the digester system to a position which is substantially at the same level as the extraction, or downstream thereof, and thereby constitute part of the process liquid in the subsequent treatment zone. The process results in improved tear strength, beatability, bleachability and reduced color reversion, and increased yield across the digester.

Most filtration system include a first pipe array located above the rounded base which provide for backwashing of the upper portion of the tank, but leaves the base area below the first pipe array stagnant and subject to the growth of harmful bacteria.

The second array is configured to follow the contours of the base of the tank to give it a greater cross sectional area than a flat array. This configuration results in greatly improved effectiveness over that provided by the conventional single flat array.
