Excessive Chemical Makeup Due to Inefficient Recovery and High Potassium/Chloride Accumulation
What Is Excessive Chemical Makeup Due to Inefficient Recovery and High Potassium/Chloride Accumulation?
In the kraft recovery cycle, potassium and chloride build up in the chemical loop over time. High K/Cl ratios reduce causticizing efficiency, requiring more fresh NaOH makeup, and cause scaling and plugging. Unfair Gaps analysis identifies K/Cl management as one of the most underoptimized cost drivers in kraft mills.
How This Problem Forms
Financial Impact
Who Is Affected
Process engineers and mill managers responsible for chemical cost optimization at kraft mills benefit most. Unfair Gaps research shows mills with softwood furnishes and closed water circuits have highest K/Cl risk.
Evidence & Data Sources
Market Opportunity
Chemical recovery optimization for kraft pulp mills is a niche but high-value consulting and software market. Unfair Gaps methodology identifies mills with highest K/Cl accumulation.

Frequently Asked Questions
How does potassium/chloride accumulation increase costs?▼
High K/Cl ratios reduce causticizing efficiency, requiring more fresh NaOH makeup. They also cause scaling and plugging that reduce equipment performance — combining to drive 10–20% above-benchmark chemical costs.
How can kraft mills reduce K/Cl accumulation?▼
Strategic liquor purging combined with green liquor clarification is the standard solution — Unfair Gaps analysis shows optimized purge strategies reduce chemical makeup costs by $300K–$1.5M annually.
