Abstract: | A historical record of monthly chemical makeups for a North American pulp mill has been analyzed by time series methods. The analysis yields estimates for the reduction in sulfur makeup resulting from each of three separate pollution abatement moves: black liquor oxidation, blow heat recovery, and cooking liquor sulfidity reduction. Further analysis yields estimates of sulfurous emissions and of the substantially lower emissions which could have been achieved if sulfidity management had been incorporated in the program. |
