The objective of this project was to define the potential odor contribution of selected process streams in the kraft industry that are routinely sewered. A procedure was suggested that can be used for this purpose. Use of a dynamic olfactometer and odor panels to measure odor thresholds determined by complete volatilization of the sample or stripping of the sample were unsuccessful. No correlation between odor threshold and reduced sulfur concentration in the gas stream as measured by gas chromatographic techniques could be obtained. Odor panels were employed using the head space analysis and the forced-choice triangle technique. It was shown that identifiable odor threshold values were more reproducible and judged more meaningful than simple odor threshold values. It was shown that independent of mixing techniques, odor intensities of kraft mill process streams were additive. This was demonstrated for an acid sewer containing first chlorination stage effluent, digester condensates, and multiple-effect evaporator condensates; and for a total mill effluent with multiple-effect evaporator condensates, decker water, and odor-free dilution water used as make-up.
