摘要： The method is for production of green liquor in association with a causticizing process during recovery of chemicals in manufacture of sulphate pulp. A smelt (14) of chemicals principally consisting of Na2S and Na2CO3 from a soda boiler (1) is provided. Weak liquor (15) that contains dissolved NaOH and CaO is provided. A dissolving tank (2) is provided in which the smelt (14) from the soda boiler (1) is dissolved in the weak liquor (15) it order to form green liquor (16). A solution of NaOH is added to the weak liquor (15), at a position before the weak liquor (15) is added to the dissolving tank, in order to increase the concentration of NaOH in the weak liquor (15) such that a fraction of CaO that is presently dissolved in the weak liquor (15) precipitates.

摘要： A filtering apparatus comprises: a pressure vessel; a plurality of filter elements arranged within the pressure vessel, the filter elements each having an upper end, a lower end and a side wall; filling bodies positioned within the filter elements; a first conduit for introducing compressed gas into the pressure vessel; a second conduit for transporting unfiltered liquid to and from the pressure vessel; and a third conduit for removing filtrate from the pressure vessel and transporting back-flushing liquid to and from the filter elements, the third conduit positioned proximate to a bottom portion of the pressure vessel and attached to the lower ends of the filter elements, such that the third conduit provides a support structure for the filter elements and the back-flushing liquid introduced via the third conduit fills the filter elements in a direction from the lower ends toward the upper ends, the volume of back-flushing liquid introduced into the filter elements limited by the filling bodies. A method of operating the filtering apparatus is also disclosed.
