Abstract:
A method for automatically monitoring liquor composition within a kraft process, the method comprising the steps of:performing capillary electrophoresis upon a liquor sample containing at least one ion to obtain data over time which relates to a predetermined property of at least a portion of the liquor sample, wherein the liquor sample is selected from the group consisting of black liquor, green liquor and white liquor;automatically identifying at least one peak within the data, said identifying step comprising determining those portions of the data which exceed a predetermined threshold and which form a respective peak;separately determining an area under respective ones of the peaks;automatically analyzing the peaks identified within the data to determine if a peak is unacceptable; andautomatically determining a concentration of a respective ion based upon the area under the peak which corresponds to the respective ion and which is acceptable.
