Modified batch pulping processes recycle the black liquor from the end of the cook to absorb the sulfur preferentially onto the chips. This absorbtion of sulfur, minimizes the soda type reactions during kraft pulping. The objective of this study was to study the impact of varying the sulfidity in a modified batch process from 15 to 45%. In a conventional kraft cook sulfidity has a significant impact on yield and pulping rates up to about 15% sulfidity.
