The effects of steam stripping contaminated Kraft condensates were evaluated in relation to the removal of odorous sulfur-containing compounds. The investigation was carried out in a packed distillation column. The mill streams investigated were multiple effect evaporator condensates, waste heat evaporator condensates, and concentrator condensates.
Measured volumes of distillate were removed and analyzed for chemical oxygen demand by oxidation, and for component make-up by gas chromatography.
This study indicates that the use of steam stripping not only reduces the amount of sulfur-containing compounds, but reduces mill water requirements and the BOD load placed on effluent treatment facilities
