Organic deposits like pitch and extractives are a major challenge in pulp production. These substances, derived from natural resins and organic compounds in wood fibers, are frequently observed in pulp production processes that prioritize minimal water usage. Their hydrophobic nature causes them to form sticky deposits that impact critical mill equipment.
The effects of these deposits are costly and widespread. They clog washers, screens, and refiners, disrupting operations and degrading pulp quality with contaminants like specks and stickies. They also lower washing efficiency, reduce water clarity, and impact pulp quality. Contamination often leads to unplanned maintenance and downtime, driving up costs. Controlling organic deposits is essential for stable operations, better fiber quality, and improved mill performance.
Properties and Benefits
Our organic deposit control solutions are designed to address and mitigate the challenges posed by pitch and extractives in pulp mills. Using innovative, proven mechanisms, these solutions target deposition issues at their source:
- Dispersants: Stabilize pitch particles in process water, preventing buildup and deposit formation.
- Charge neutralization: Reduces the tackiness of pitch particles, minimizing adhesion to equipment.
- Fixation agents: Bind extractives to fiber surfaces, keeping them within the fibers and out of circulating water.
- Surfactant-based emulsification: Removes hydrophobic residues from machine components through efficient emulsification.
Implementing these deposit control solutions offers clear benefits. Mills experience fewer pitch-related disruptions, smoother pulp production, and less downtime for cleaning. Pulp quality improves and resource usage can be optimized with lower chemical usage.
