Chemical recovery systems functionalit is important for pulp mills, ensuring cost-efficient operations and supporting sustainability goals. However, their performance is often challenged by inorganic deposits, which can disrupt critical components and processes. Inorganic deposits form when dissolved minerals precipitate under high-temperature and high-alkalinity conditions. They are most common in areas like heat excahngers, where scaling lowers heat transfer and raises energy costs; recovery boilers, where fouling causes slagging and disrupts combustion; causticizing plants, where scaling hinders green liquor-to-white liquor conversion; and lime kilns, where deposits reduce the productivit..
The impact of scaling and fouling includes increased energy use, higher maintenance costs, reduced chemical recovery efficiency, and accelerated equipment wear, shortening system lifespan. Inorganic deposit control can deduce these risks and helpts to maintain efficient and cost-effective operations.
Properties and Benefits
Banmark’s inorganic deposit control solutions are engineered to combat scaling and fouling challenges in chemical recovery systems. These solutions employ technologies, including:
- Crystal modification technology prevents hard, adherent deposits by altering crystal growth.
- Threshold inhibition stops scaling at the molecular level by disrupting nucleation.
- Dispersing agents keep particles suspended, preventing buildup on surfaces.
- Compatible with high-temperature and high-alkalinity environments for reliable protection in tough conditions.
These technologies deliver measurable benefits, including improved heat transfer efficiency in evaporators and recovery boilers with lower energy use. They reduce the need for frequent chemical cleaning and unplanned shutdowns, cutting downtime and extending the lifespan of critical equipment by preventing deposit buildup. By stabilizing chemical recovery, they ensure consistent, high-quality pulp production while improving sustainability through better chemical reuse and enhanced process efficiency.
