摘要： Oxidized white liquor is heat treated to increase the concentration of PSUV measured at 285 or 286 nm or PSVIS measured at 416 nm and the PSUV/PSGR or PSVIS/PSGR ratio, whereby the content of active polysulphide in the total polysulphide is increased which active polysulphide can be exploited to increase pulp yield in Kraft pulping.

摘要： An on-line automated analyser of macrocontaminants is described. The analyser is for a pulp and/or a white water stream, the analyser comprises: a pulp classifier separating a sample from the stream into a fraction of macrocontaminants; a contaminant chamber enclosing a contaminant cell receiving the fraction; an optical chamber comprising an optical detector connected to the cell capturing at least one detected image; and a control chamber taking the at least one detected image and conducting an image analysis to determine type and quantity of at least one macrocontaminant in the fraction. The method of analysis of macrocontaminants is also described herein, the method comprises: separating a sample from the stream into a fraction of macrocontaminants; producing at least one detected image by optical measurement of the fraction; and analysing the at least one detected image and determining the quantity and type of at least one macrocontaminant in the fraction.
