Excessive Chemical Makeup Due to Inefficient Recovery and High Potassium/Chloride Accumulation
Definition
In pulp cooking and chemical recovery, accumulation of potassium and chloride in the black liquor and recovery boiler requires large purge rates to prevent operational issues like superheater corrosion and reduced efficiency. This leads to ongoing loss of recoverable pulping chemicals (sodium carbonate and sulfate), necessitating continuous purchase of makeup chemicals. Inefficient recovery processes fail to optimize chemical circulation, resulting in sustained higher operational costs across mills, especially those processing eucalyptus or hardwoods.
Key Findings
- Financial Impact: $50-100 tons/day in caustic makeup savings potential (implying equivalent recurring loss without optimization)
- Frequency: Daily
- Root Cause: High potassium and chloride content in wood/liquor concentrates in recovery boiler, limiting purge efficiency and chemical recovery rates without advanced processes

Financial Impact
$40,000-100,000 annually in excess inventory carrying costs, working capital impact, and warehouse utilization • $50,000-120,000 annually in increased QA labor, recipe adjustments, and product consistency issues tracing back to variable supplier pulp chemistry • $50,000-150,000 annually per mill supplier (amortized across customer base) due to embedded chemical makeup recovery losses
Current Workarounds
Excel spreadsheet tracking supplier cost trends; manual emails requesting volume discounts or price breaks; WhatsApp coordination with suppliers about chemical surcharges • Manual inventory tracking via Excel; phone calls with suppliers to confirm batch schedules; stockpile buffer inventory to hedge against supply variability • Manual lab notebooks tracking cooking parameters; visual assessment of black liquor color and consistency; phone calls to supplier asking about recent recovery boiler maintenance
