    • The invention relates to a system and method for washing and thickening a lime mud slurry. A filter 1 is used wherein the liquid volume in the filter vat is divided by at least one partition wall 19 into at least 2 independent vat parts and that these vat parts are fed with lime mud slurry in parallel, by individual supply lines from at least one lime mud storage tank 30a/30b. When a clean out operation of one independent part is activated, is the lime mud vat flushed out to the preceding lime mud slurry container 30a/30b, while all other independent parts are still in operation. By using this parallel operation could lime mud sedimentation in the filter vat be broken up at regular intervals, and a continuous feed of washed and thickened lime mud be made to the lime kiln, maintaining the structural integrity of the kiln.

    • The present invention relates to a method for pyrolytic decomposition of a material in a pyrolysis reactor (100) intended for continuous operation comprising supplying the material towards the pyrolysis reactor (100), pyrolysing the in the pyrolysis reactor in the absence of air, removing gas and residual products resulting from the pyrolysis process. The supplying step comprises: feeding the material through a first feeding means comprising a first feeding conveyor screw (3) arranged in a first supply channel and driven by a first driving motor (2) towards a second feeding means (6) comprising a second feeding screw conveyer unit (7) driven by a second driving motor (4). The first feeding channel is slanted upwards from an input towards the second feeding channel. The speed of the second conveyor unit driven by the second motor (4) is preset depending on the material to be pyrolysed. A material compression related feature in the second feeding means (6) is detected by a sensing arrangement (60), and detected current values are used for controlling the first driving motor (2) to obtain a substantially constant or desired degree of compression in the second feeding means (6).
