The cooking stage in pulp production is a critical step that impacts fiber quality, pulp yield, and process efficiency. In this phase, wood chips undergo chemical treatment at specific temperatures and pressures to remove lignin, while preserving cellulose and hemicellulose. Cooking additives are specialized chemicals that enhance the cooking process by improving lignin and extractive removal, protecting fibers, and optimizing chemical use, ensuring consistent pulp quality and efficiency.
Pulp mills face challenges during cooking, such as incomplete lignin removal, which reduces brightness and raises bleaching chemical use; fiber degradation, which weakens quality; scaling and deposits, which reduce equipment efficiency; and raw material variability, causing inconsistencies. Inefficient cooking increases costs, lowers fiber quality and yield, impacts product performance. Cooking additives help solve these issues, boosting efficiency, pulp quality, and sustainability.
Properties and Benefits
Banmark’s cooking additives are formulated to optimize the pulping process and address key challenges with precision. These solutions include:
- Delignification enhancers, accelerating lignin removal while preserving valuable carbohydrates in fibers.
- Extraction agents, promoting efficient removal of extractives to enhance pulp quality.
- Selective separation agents, ensuring effective separation improving overall process yield and pulp strength.
These cooking additives improve delignification efficiency, reducing bleaching chemicals and costs while enhancing fiber yield and strength for high-quality pulp. They also minimize scaling, fouling, and maintenance downtime, stabilizing chemical recovery cycles for better operational efficiency.
Usage and Applications
Banmark’s cooking additives are versatile and can be applied across a range of pulp production systems and processes. They are compatible with:
- Batch and continuous digesters, where they improve cooking uniformity and chemical diffusion.
- Both kraft and sulfite pulping processes, ensuring adaptability to different chemical compositions.
- Softwood and hardwood pulping, providing tailored solutions for diverse raw fiber sources.
- Chemical recovery cycles, preventing harmful interactions that reduce recovery efficiency.
To maximize effectiveness, Banmark provides application insights and strategies, including dosage optimization based on process conditions. This enables mills to achieve consistent cooking performance. The goal is to dynamically adjust chemical feed rates, while compatibility with other pulping additives ensures seamless integration into existing systems for improved production outcomes.
